Cranking and cranking and nothing, what a pain! I hear you. I’m a mechanic and very shortly we’ll check your timing and we’ll be well on the way to figuring out what’s going out with your dirt bike.

When a dirt bike timing is off, you may experience the following symptoms:

• No start
• Runs but no power
• Runs but backfiring
• The engine won’t crank just clicks
• Kickstart won’t move

In this post, you’ll learn, why dirt bike timing is important, you’ll learn how to check and reset the timing on both a 2 stroke and 4 stroke motor.

What is Dirt Bike Timing?

Timing is important but you already know that. But what is meant by timing? An engine needs three ingredients in order to run:

1. Fuel (air and gas mix)
2. Spark
3. Compression

When referring to timing on a regular 4 stroke motor we may be referring to ignition timing or valve train timing and we’ll get into that in a little more detail below.

When referring to timing on a 2 stroke we are referring to ignition timing only, since a 2 stroke doesn’t have a valve train there are no valves to time.

Checking and adjusting timing is different depending on what type engine your bike has. Checking and setting the timing on a two stroke as said relates to the ignition timing. If you have a two stroke bike you can jump ahead to checking and adjusting timing here.

Checking timing on a four stroke is a little more work and typically when we refer to timing on a 4 stroke bike we are referring to valve train timing, since ignition timing for most four strokes is not manually adjustable. The timing is advanced and retarded by the CDI/ECU controller only.

Four stroke engines

The purpose of engine timing is to prepare the combustion chamber so that the conditions are perfect for ignition (explosion). If the fuel mix is wrong (too much air or too much gas), if the plug doesn’t spark at the correct moment or the cylinder doesn’t compress, the mixture won’t ignite and the engine won’t start.

Most engines are known as four strokes and this describes the timing of how the three main ingredients are added to the mix, if you like.

An engine (4 stroke) may be thought of as unit with two halves, the bottom end, known as the block with the crankshaft being the main component, and the top end known as the cylinder head with the camshaft being the main component.

The two halves must work in harmony in order for your dirt bike to perform. And to do that the two components, the crankshaft, and camshaft must be synchronized.

An assembly known as a timing assembly is employed and charged with the task of synchronizing (timing) both these components. Typically a timing assembly includes sprockets, a chain, guides, and a tensioner.

Let’s take a look at those four strokes (stages) briefly now.

First stroke – The rotating crankshaft causes the intake valve to open and the piston to fall which in turn draws the air-fuel mix into the cylinder.

Second stroke – The rotating crankshaft causes the intake valve to close sealing the cylinder and allowing the rising piston to squash and compress the air-fuel mix into the top of the cylinder (combustion chamber).

Compressing the mix, heats it through friction making the conditions perfect for combustion.

Third stroke – The rotating crankshaft passes x° BTDC (Before Top read Center) which triggers the ignition system pickup sensor which in turn fires the spark plug through the CDI and coil.

This is known as the power stroke as the explosion pushes the piston down the cylinder.

Forth stroke – The rotating crankshaft causes the exhaust valve to open and the piston to rise forcing the spent gases out of cylinder.

And the process starts over at the first stroke.

How To Check 4 Stroke Dirt Bike Timing

Checking the timing is not difficult, all bike engines will have a crankshaft marking engraved which corresponds to a camshaft sprocket marking. Checking timing then is as simple as making sure they align precisely.

Some components may need to be removed in order to access the timing marks, but usually, manufacturers fit removable covers.

I covered the process below, but note all makers will approach this slightly differently, some will be single cam, some twin cam, and some older bikes may not be OHC (Over Head Cam) at all.

Timing check steps as follows:

• Remove spark plug.

• Remove the side cover timing inspection cover
• Remove flywheel fastener access cover

• Set the engine to TDC by turning crankshaft CCW until mark 1 (flywheel mark) aligns with side cover mark
• Now check the cam sprocket marks 2 and 3 align

This is a typical see up but your bike may be single cam, but I think you get the general idea.

If your marks don’t align then timing will need to be adjusted. We cover that below, but just before we jump to adjusting timing we should ask why the timing is off in the first place. It may be a warning sign of other issues which I cover below, you can check that out here.

Checking & Adjusting 2 Stroke Dirt Bike Timing

It should be noted not all 2 stroke bike timing is adjustable but this is something you can check in your owners manual before going to the trouble of pulling off a side cover.

Checking 2 stroke timing is usually undertaken in one of two ways. Tools however are required to nail this professionally.

Head cover on – For this process we’ll need a dial gauge to check and adjust the ignition timing. It’s not a difficult task, just a little tedious and you’ll need the specs for your make and model bike. If you don’t have a dial gauge you’ll find one here on the Dirt bike tools page here.

I’ve covered that below, note the side cover will need to be removed also.

Head cover off – If you already have the head off, then a simple timing tool may be used to check and set the piston to the correct ignition timing mark. If you don’t have a timing tool gauge you’ll find one here on the Dirt bike tools page here.

I’ve covered that below, note the side cover will need to be removed also.

Checking timing with head cover off

With the correct timing tool selected for your engine, use the following steps to time your engine:

• Place the timing tool on the jug and rotate the flywheel CCW until the piston kisses the tool.

• Now check the timing mark on the flywheel corresponding to the stator base plate.
• If not, loosen the stator baseplate fasteners and rotate so the markings align and tighten again.
• Job done!

Check timing with the headcover on

This process is very similar but since we don’t have the same access to the piston we’ll need a different tool. For this, we’ll need a dial gauge.

The process is as follows:

Remove the spark plug and fit the dial gauge at the appropriate height.

• Rotate the flywheel CCW to TDC
• Now zero out the dial gauge
• Rotate the flywheel CW to the specified measurement

• Now check the ignition timing mark on the flywheel (orange) corresponds to the stator baseplate mark (green)
• If not, loosen the stator baseplate fasteners and rotate so the markings align and tighten again
• Job done!

The engine is set to the correct ignition timing BTDC.

Some bikes may have three timing marks and that’s super useful for the MacGyver types that like to wing it.

The 3 marks represent the window of adjustment available to us. It’s a case of adjusting, testing, and readjusting until it feels right, who needs a dial gauge tool?

Why does Dirt Bike Timing go Out?

Engine timing is serious business when it’s out a little performance suffers but if the timing is out a lot or if timing assembly fails it often ends in disaster for the engine (4 stroke motor). So why does timing move out of sync in the first place?

As with checking and setting timing, why the timing moves out of sync depends on your engine type.

Why 2 Stroke timing goes out

A 2 stroke ignition timing typically needs adjusting after a rebuild and is often forgotten.

Why 4 Stroke timing goes out

The most common reasons a 4 stroke timing moves out of sync include:

• Worn chains – stretch with age and poor oil quality
• Worn timing sprocket – wear and tear and poor quality oil
• Incorrect fitting after rebuild
• Failed or worn chain tensioner
• Failed or worn timing chain guide

If you find worn timing components you’ll need to go ahead and replace the tensioner, guides, and the chain. In addition, you’ll need to replace the side gasket together with cam cover gasket.

To replace the chain guides and tensioner we’ll need to do the following:

• Remove the top side cam (replace gasket)
• Set timing to TDC
• Remove tensioner
• Remove cam caps (star pattern)
• Remove side cover (replace gasket)
• Pull flywheel (need flywheel puller) careful of key
• Remove chain guide and chain

Replace chain and guide and rebuild in reverse order and set timing as per below. Careful to follow correct torque specs in relation to flywheel and cam caps. Replace side cover gasket, cam gasket and tensioner gasket otherwise we’ll be chasing oil leaks.

How To Set 4 Stroke Dirt Bike Timing

Setting the timing isn’t difficult, we’ve already covered how to access and check the timing marks. Setting the timing then requires a few more steps. We’ll need to remove the tank, covers, air box, throttle body/carburetor, etc, wherever else we need to access the cam cover. For the following steps, we’ll assume you have clear access to the cam cover.

They are as follows:

• Remove spark plug
• Remove timing covers
• Remove cam cover
• Set engine to TDC
• Note timing marks

• Remove tensioner

• Loosen cam caps (star pattern)
• Remove or rotate the cam to realign the chain on the cam sprocket mark
• Refit cam cap and torque to spec (star pattern)

Careful to follow correct torque specs when tightening the cam caps and cam cover. Set the tensioner and fit (fit new gasket) and check tensioner has fired.

Signs of bad dirt bike coil

Dirt bike troubleshooting

The post Will Dirt Bike Start If Timing Off? Run this test appeared first on ATVFixed.com.

A coil is a critical ignition system component and your bike won’t run without them. A coil works hard, and for the most part, they are reliable, but they do fail. You are in the right place, I’m a mechanic and very shortly, you’ll know if your dirt bike coil is good or bad.

The top four symptoms of a bad dirt bike coil include:

1. No start
2. No spark from the spark plug
3. Hard hot starting
4. Shuts down when hot

In this post, you’ll learn what the symptoms of a faulty dirt bike coil are, how to diagnose a faulty coil, and of course how to fix it.

Symptoms of Faulty Dirt Bike Coil

Here we’ll look at the most common symptoms of a bad dirt bike coil in a little more detail. But just before we look at them, it is worth knowing that coils commonly fail in one of two ways. The symptoms associated with each type of coil failure are different.

1. Total failure – (stops working altogether)
2. Fails when hot – (works when the engine is cold)

Common dirt bike faulty coil symptoms are as follows:

No start – no start is the number one symptom associated with total coil failure. That said a dirt bike may not start for a ton of reasons and so this common symptom isn’t conclusive evidence of coil failure in itself.
No spark from the spark plug – no spark at the plug is if you like the first solid clue we are dealing with an ignition system fault and of course, as you know the coil is a major player in the ignition system so we’ll already suspect we could be looking at total coil failure. But as before we’ll need to check that coil first.
Hard hot starting – commonly associated with a failing coil as opposed to a totally failed coil. This type of intermittent failure can be irritating to catch as it isn’t always present and in some cases doesn’t even happen on every hot start.
Shuts down when hot – commonly associated with a failing coil. May be intermittent or regular as clockwork when the engine heats up. I’ve covered this exact issue previously and you can check it out here – Dirt bike won’t start when hot

While it’s true the coil is a major critical component of the ignition system that commonly fails, it must be said it isn’t the only component of the system that can cause issues. The presence of one or more of the above symptoms is not conclusive proof of coil failure.

And so before reaching for a new coil, let’s quickly test it and we’ll do exactly that right now.

How to Test Dirt Bike Coil

Checking spark at the spark plug is among the very first checks we make when we suspect a coil issue. Testing the coil though can be hit and miss without the correct tools. In the field, we can run a MacGyver-style hack by grounding the spark plug on the engine and checking for signs of life (we’ll cover that below).

The problem with this type of testing is, that it doesn’t load up the ignition system. And loading the system up and stressing is exactly what we want to do when testing.

First, let’s cover the MacGyver hack for in-the-field spark checking.

Checking spark MacGyver style as follows:

• Remove plug cap
• Remove the spark plug
• Refit the cap
• Ground the plug on the engine
• Crank over the engine
• Check plug for spark

Two results are possible:

1 No spark at the spark plug – Check the grounding. (Grounding the plug means making the metal body of the spark plug make good contact with bare metal on the engine.) If the plug isn’t grounded correctly the plug won’t fire and that often leads to misdiagnosis. If you are happy with the grounding, the plug should be swapped out with a spare to eliminate it as a possible cause of no spark

2 The plug sparks – Great! But remember this type of spark testing doesn’t stress the ignition system and so finding a spark isn’t conclusive.

The correct test is the inline ignition system test and we’ll cover that next.

The inline tool is especially useful when searching for intermittent hot start issues as the engine will run with the inline tool in place and of course, the tools inspection window may be viewed for signs of spark failure as the engine warms up and approaches its failure point.

The inline ignition system test is as follows:

• Remove plug cap
• Connect plug cap onto the inline tool
• Connect the inline plug cap to spark plug
• Crank engine
• Check for spark

Two results are possible:

1 The plug sparks – If you have a spark when testing with an inline tester, your ignition system is good. That said, if you still feel you have an ignition system issue, you can check the following:

• Check the correct type of spark plug fitted (heat range)
• Check plug condition and gap
• Check for grounding ignition system wiring (Kill switch)

2 No spark at the spark plug – It is very likely your coil is the root cause of the no start but there are as said other components that could cause no spark. To produce conclusive evidence we’ll need to check coil resistance.

A DVOM is also known as a voltmeter, but we won’t be checking voltage, we’ll be checking coil resistance. You can find a DVOM I use here on the ATV tools page.

Coil Test

When testing a coil we’ll run three tests:

1. Primary coil resistance test
2. Secondary resistance test
3. Plug cap resistance test

Before running this test you’ll need to isolate your coil by removing all block connectors and removing the coil cap. Running a resistance test while the coil is connected to the bike’s wiring circuit won’t work. Resistance must not be executed on a live circuit.

1 Primary coil resistance test as follows:

• Remove all coil wiring
• Set your meter to resistance Ω
• Test the primary windings by placing the probes as per the picture

The resistance readings 1.16 to 2.64 are typical but your bike’s spec will likely differ, check your online users manual.

2 Secondary resistance test as follows:

• Meter set to resistance Ω
• Test the secondary windings by placing the probes as per the picture

The resistance readings 8.64 to 12.96 are typical but your bike’s spec will likely differ, check your online users manual.

3 Plug cap resistance test as follows:

• Meter set to resistance Ω
• Test the secondary windings by placing the probes as per the picture

The resistance readings 1.16 to 2.64 are typical but your bike’s spec will likely differ, check your online users manual.

If your coil is within your manufacturer’s spec, your spark plug is correctly gapped, and it is the correct type of plug (heat range) then you are all good on the ignition system.

If your bike fails to start, check the following:

Air filter – a blocked or mouse infested air filter is top of the list for good reason

Following correct starting procedure – choke, kill switch, etc.

Flooded engine – constantly attempting to start a hard starting bike may cause flooding.

Fuel-related issues – bad gas, fuel starvation, dirty carb, etc. I’ve covered a hack for checking for fuel issues quickly in this post – ATV won’t start. Sure it’s an ATV but the principle is identical.

Valve lash – the engine must breathe and the valves allow air/fuel mix in and spent gases out.

Timing out – timing is important, spark must occur at a critical moment.

Compression issue – poor compression will cause a no-start.

Other Causes of No Dirt Bike Spark

Here’s a shortlist of other root causes of no spark:

• Faulty stator
• Faulty pickup
• Faulty ignition
• Faulty CDI
• Kill switch short

Dirt bike troubleshooting

The post Signs of Bad Dirt Bike Coil – Top 4 signs appeared first on ATVFixed.com.

Stators are the unseen component, indeed most riders don’t even know it exists. Without the stator, we going nowhere, a stator is the birthplace of your dirt bike’s ignition system voltage.

All dirt bikes require a stator in order to produce voltage to run the ignition system, in addition, the stator provides power for lights, if fitted, and charges the battery if fitted.

In this post you’ll learn where a dirt bike stator lives and what it does, you’ll learn the symptoms of a faulty stator and finally, you’ll learn how to test a stator using a DVOM.

Where is a Dirt Bike Stator

The stator is fastened behind the left side aluminum cover of your engine (most engines).

It must be located there because it requires both a rotor and the rotating motion of the crankshaft in order to produce voltage.

What a Dirt Bike Stator Does

A stator is responsible for producing the voltage required to run your bike’s electrical system. Even bikes fitted with a battery and electric start only use that battery power to crank over the engine. As the bike starts the stator takes over responsibility for all the electrical demands, and in addition for battery-fitted bikes, the stator must also charge the battery, replacing spent voltage during the starting process.

But no matter if your bike has a battery fitted or not, it will require voltage to run the ignition system (fire the spark plug), and that’s the stator’s job.

So the stator is a really critical component, no stator means no spark plug activation and means no fun!

How Does it Work?

The stator consists of multiple coils of copper wire (bikes where a battery is fitted, coils are typically grouped together into three circuits) arranged in a circle and attached to the backside of the left engine side cover. When the side cover is fitted to the engine, the stator coil arrangement fits neatly inside a cavity on the rotor.

The rotor is fixed to the crankshaft and rotates as the engine is kickstarted or cranked over with the starter. As the rotor spins, magnets attached to the inner surface pass over the stationary stator coils and this excites the coils and produces voltage.

The voltage is however alternating current (AC) and must be converted to direct current (DC) before a dirt bike electrical system can make use of it. And to perform that function your bike is fitted with a rectifier. It rectifies the voltage, meaning it converts it from AC to DC.

For bikes fitted with a battery, a rectifier with an integrated regulator regulates how much voltage goes to charge the battery. Too little is no good obviously but too much is bad also, a faulty regulator will kill a battery by overcharging it.

Your bike’s stator likely also incorporates the pickup (most do). The pickup has a special function, it signals the CDI or ECU when it’s time to fire the spark plug.

A new stator will come with a new pickup.

Common Faulty Dirt Bike Stator Symptoms

Stators work hard, you already know that, so you won’t be surprised to know they fail regularly. Here are some common symptoms associated with stator failure.

• No start
• No start when hot
• Engine stalls when warm
• Engine misfiring
• Engine backfiring
• Engine won’t rev
• Engine no power
• Engine black smoke

How to Test Dirt Bike Stator

To test a dirt bike stator we have a couple of options. However, if our dirt bike isn’t running we have only one option open to us, the Static test. Let’s take a look at both of these right now and how to execute them like a pro.

You’ll need a DVOM tool in order to run these tests and you can check out the DVOM I recommend here on the AV tools page.

Dynamic Dirt Bike Stator Test

This test will suit you if your dirt bike runs and idles, conversely if your bike doesn’t run you’ll need to jump on down to the static test below.

In the dynamic test, we’ll unplug the stator wiring block connection and we’ll check AC voltage with the engine running (2500 rpm) using our DVOM.

The dynamic test is as follows:

Locate the stator block connector and disconnect.

With DVOM set to AC (~) voltage and the bike running check:

• A to B
• A to C
• B to C

As per the picture, typically the AC voltage reading between 15 and 60. Depending on spec and rpm, but check your makers’ spec.

Static Dirt Bike Stator Test

The static test suits a running dirt bike or a nonstarter just the same. For this test, we’ll use a DVOM set to resistance (Ω). We’ll be checking continuity in the circuit.

Continuity simply means we’ll be checking for broken wires within our copper coils. To do that, we’ll disconnect the stator wiring block connector. We use the DVOM to send a small charge through one terminal using the positive probe, and using the negative probe on a second terminal, we read how much of that voltage actually makes it through (if any).

The static test is as follows:

With the DVOM set to resistance (Ω) and the stator plug disconnected, measure the following:

• A to B
• A to C
• B to C

Typically a reading between .1 and 1 Ω is OK but check your makers’ spec.

In addition, we can check for a short to ground. With the DVOM set to resistance (Ω) and the stator plug disconnected, measure the following:

• A to G
• B to G
• C to G

No continuity means there’s no short.

The post Do All Dirt Bikes Have a Stator? A beginners guide appeared first on ATVFixed.com.

I’m a mechanic for twenty-five years, and bump starting engines is all part of the day job. If your dirt bike isn’t fitted with kickstart or even if it is, this post is for you. Very shortly you’ll learn a life skill and you’ll be tearing it up.

The top two ways to start a Dirt bike without using a kickstart include:

1. Hill bump-start
2. Push bump-start

In this post, you’ll learn the top two techniques for starting your dirt bike without using a kickstart. These techniques will work for all dirt bikes, however, fuel-injected bikes will require a functioning battery. we cover it all below, and we also some lesser-known dirt bike starting techniques.

1 The Hill Bump-start

The hill bump-start is the number one way to start a dirt bike without using a kickstart. It’s not only the easiest but it’s the safest technique also.

You’ll need a hill to perform the hill bump-start successfully. We’ll use gravity to propel the bike and rider downhill, then we’ll convert that motion into the energy we need to crank over the motor and start the engine. Sounds simple, right? Well, it is!

Tools you’ll need: Rider and a Hill

The Hill bump-start process:

Step One – Move the bike to the top of a hill – the steeper the better and somewhere the rear wheel will gain traction (a sealed surface is ideal, not a muddy trail)

Step Two – Turn the gas and ignition system “On”

Step Three – Straddle the bike, pull and hold the clutch lever, and place the bike in 2nd gear

Step Four – Push off and stand up (stand up on the pegs)

Step Five – When you’ve gathered sufficient speed, drop your weight (ass) onto the seat while simultaneously releasing the clutch lever (dropping your weight on the seat is important as it helps generate additional traction at the rear wheel precisely when it’s needed)

Step Six – Tear it up

For most riders, this simple hill bump starting hack works a treat. However, when it doesn’t, it is usually because of one of the following common reasons:

• The ignition system is not turned on
• Fuel not on
• The rider fails to gather enough momentum
• The rider fails to slam the seat at the correct time
• Bike flooded with gas
• Fouled spark plug
• Faulty battery (covered below)

2 Push Bump-start

The Push bump-start technique employs an identical starting technique to the Hill bump-start we’ve just covered above. But the push bump-start has a few extra steps that will require a higher skill level and some physical exertion.

This technique is used when the terrain doesn’t offer the rider the opportunity of taking advantage of a hill.

Tools you’ll need: Fit rider

The Push bump-start process:

Step One – Move the bike to a suitable space – a sealed surface would be ideal, somewhere the wheel can gain traction

Step Two – Turn the gas and ignition system “On”

Step Three – Stand on the left side of the bike, pull and hold the clutch lever, and place the bike in 2nd gear (note: some bikes may be challenging to push when in gear with the clutch pulled and held if so skip placing it in gear until you have built up sufficient momentum. This adds an extra degree of difficulty but not rocket science)

Step Four – Start pushing

Step Five – When you’ve gathered sufficient speed, through your leg across the bike and drop your weight (ass) onto the seat while simultaneously releasing the clutch lever (dropping your weight on the seat is important as it helps generate additional traction at the rear wheel precisely when it’s needed)

Step Six – Tear it up

Next, we’ll cover some of the common reasons this technique hasn’t worked. And you won’t be surprised to see that many of the reasons are related to the execution of the technique.

• Not gathering enough speed
• Taking too long to mount the bike and drop clutch
• Failing to coordinate weight on the rear wheel and dropping the clutch
• Faulty battery (covered below)

Other Techniques for Starting a Dirt Bike without Kickstart

Here you’ll find some other techniques for starting a dirt bike without using a kickstart. That said not all these techniques will suit all dirt bikes. To decide which options will work best, we’ll need to know:

A – If your bike is fitted with a battery and starter motor (electric start or not)

B – What type of fuel system your bike uses

Electric start

If your bike is normally electric start, you’ll have the greatest number of options available to you when it comes to starting your bike without a kickstart. The two most common types at the beginning of this post should have you covered, but in addition, you’ll have options such as Jump pack use, Jumpstarting, and crossing the solenoid. (all covered below)

That said, successful execution of these techniques will depend upon what components have caused your bike to fail to start on the button in the first place.

You can check out the electric start bike options here.

What Fuel System?

Most dirt bikes and all older bikes are fitted with a carburetor and more modern bikes especially higher-end modern dirt bikes will likely employ a fuel-injected fuel system. Either type may or may not have an electric start fitted.

The range of starting options, therefore, varies according to your bike’s spec.

Carburetor – carburetor bikes represent the majority of older dirt bikes and if your bike doesn’t have a battery fitted, it is a carburetor bike. That said, conversely having a battery fitted doesn’t make it a fuel-injected bike.

If in doubt, check your intake system. Although fuel-injected throttle bodies resemble carburetors in many ways they don’t employ a fuel bowl. If you find a bowl-shaped reservoir, it means your bike is fitted with a carburetor.

If in addition, your carburetor bike has an electric start, you can add the electric start techniques to the list.

Fuel-injected bikes – Fuel-injected bikes are sophisticated fuel systems that employ various electrical sensors – ATS (Air Temperature Sensor), Baro (Altitude sensor), TPS (Throttle Position Sensor), an electrically controlled fuel injector, an electric fuel pump, and an ECU (Engine Control Module (computer)).

While some dirt bikes are battery-less fuel-injected meaning they don’t need or have a battery fitted. A fuel-injected bike that’s designed to have a battery, won’t like to run without one.

A working battery is critical to many fuel-injected systems for obvious reasons. And while it may be possible to start some fuel-injected bikes with a faulty battery, it won’t run right until either battery voltage is restored or the battery is replaced. Certainly, fuel-injected bikes won’t like to run with the battery disconnected.

If in addition your fuel-injected bike also has an electric start, you can add the electric start techniques to the list.

Let’s go ahead and cover the various starting techniques open to each bike.

Electric Start Bike – Starting Options

No matter if your bike is carburetor or fuel-injected if it has an electric start you can use these starting options without using a Kickstarter.

• Jump starting – Jumpstarting is a process where we scavenge power from another bike or car (any 12-volt system) to start our bike. This works great if your bike has a battery that’s simply low on power, but won’t work if your starter or starter solenoid is at fault.

Jumpstart process as follows:

• ATV battery Positive (+)
• Donor battery Positive (+)
• Donor battery negative (-)
• Ground point

You’ll find a more detailed guide on jumpstarting here – How to jumpstart an ATV? (it’s an ATV but the process is identical)

• Jump pack – This is a process where we use a portable jump pack to start your engine. This works great if your bike has a battery that’s simply low on power, but won’t work if your starter or starter solenoid is at fault.
• Cross solenoid – This is a process where we cross the starter solenoid poles effectively bypassing the start button and solenoid. This works great if your bike has a fully charged battery and either the solenoid or start button is at fault.

If your solenoid is positioned close to the battery, avoid crossing the poles. Vented battery vapors could ignite from the arc caused by crossing the solenoid poles.

Crossing the solenoid as per the picture is a fast mechanics hack for bypassing the ignition system and testing the battery.

Be sure transmission is in neutral before crossing the solenoid otherwise the bike will lurch forward.

If the engine cranks over, it’s likely your solenoid has failed. I covered starter solenoid testing and fitting previously in this post – Dirt bike won’t start just clicks.

• Tow start – This is where a buddy pull starts your bike using theirs, you’ll need a tow rope and you’ll need to employ the bump start 2nd gear technique we covered at the beginning of this post.

Opsite footrest makes for a good towing point, and obviously, you’ll need to steer off-center.

• The belt-on-wheel technique – This isn’t recommended but in the interest of explaining all options, here it is. You’ll need a helper, a stand, and a ratchet strap belt. This is a process where you wrap a belt around the rear tire and place the bike on blocks and in 2nd gear (as per our bump-start technique at the beginning of this post) pull the belt to start the engine. The helper must be ready to clutch the bike as it’s in gear.
• Turning wheel technique – This one is highly dangerous, but we’re all adults here. You’ll need a helper and a stand. Placing the bike on stand and in 2nd gear (as per our bump-start technique at the beginning of this post) pull the rear type over using brute force. The helper must be ready to clutch the bike as it’s in gear and the puller must use extreme caution, getting a limb caught is a very real risk and not something I would recommend attempting.
• Wheel to wheel technique – Need a second bike, an experienced rider, and two stands for this one. Place the bikes on stands rear wheel to rear wheel.

This is a process where the experienced rider runs their bike in 2nd gear causing your rear tire to spin also. Releasing the clutch on your bike (as per our bump-start technique at the beginning of this post). You must be ready to clutch the bike as it’s in gear and on a stand.

• Wheelie technique – This is dangerous and I can’t recommend this one either. This will require a helper. The process is as follows. Apply the rear brake and tilt the bike upright onto the rear wheel. Place bike in 2nd gear and (as per our bump-start technique at the beginning of this post). While upright, push the bike forward, jump on and dump the clutch James Bond style!

Carburetor Bike – Starting Options

Here’s the list of starting options available to carburetor bikes, and as said, some carburetor bikes will also have an electric start. If that’s your bike, you can add the list of electric start options found above to this list.

• Tow start
• The belt on wheel technique
• Turning wheel technique
• Wheel to wheel technique
• Wheelie technique

Fuel-injected Bike – Starting Options

Since all fuel-injected bikes are equipped with a battery, you know you’ll need a functioning battery before she’ll run right. And as we said earlier, your bike may be an electric start also, and if that’s the case and it is for many fuel-injected bikes, you can add the electric start list of starting options found above to this list.

Fuel-injected starting options:

• Tow start
• The belt on wheel technique
• Turning wheel technique
• Wheel to wheel technique
• Wheelie technique

Riding can be a lot of fun, but breaking into the world of dirt bikes can prove more challenging than you might think. Those new to dirt bike riding often have many questions, and one of the most frequent questions new riders ask is, “are dirt bikes automatic?”

Dirt bikes can be automatic, semi-automatic, or manual. Automatic dirt bikes are typically smaller and less powerful than manual bikes, which makes them ideal for beginner riders and children.

Keep reading to learn more about the differences between an automatic and a manual dirt bike and whether an automatic bike would be the best choice for you.

Difference Between a Manual and an Automatic Dirt Bike?

Which type of bike should you get? It depends on what it is that you are looking for from a bike and that changes for each rider. However, knowing the differences between an automatic and a manual dirt bike can help you decide which bike suits you and your needs better.

There are four main differences between automatic dirt bikes and manual dirt bikes:

• Price
• Size
• Ride
• Safety

Price

One of the biggest differences between the two (aside from how they work) is their price tags. Automatic bikes are typically made for new riders and children and are not manufactured to perform as well as manual bikes. They are also smaller and do not feature a gearbox, which also affects the price.

A manual dirt bike costs between $5,000 – $8,000, while riders can buy an automatic dirt bike for around $2,000 or less. It is important to note that prices fluctuate depending on the brand and type of bike being bought, but automatic bikes are often much less expensive.

Size

Size is another significant difference between manual and automatic dirt bikes, as most automatic bikes are smaller and weigh much less than manual bikes. Manual bikes can be found in all shapes and sizes but are typically bigger because they sport a larger engine. On the other hand, automatic bikes are often designed for children and are smaller and less powerful.

In addition to their height, manual bikes tend to weigh more because of their heavy gearboxes.

Ride

The difference between an automatic and manual dirt bike is comparable to the difference between an automatic and manual car because, with both, drivers must learn how to switch gears while driving the manual vehicle. Unlike driving an automatic, which switches the gears for you.

Although it depends on the rider, most people believe automatic dirt bikes are easier to ride, and this is especially true if you are just learning to ride. Knowing when and how to switch gears can take time to learn and can sometimes become tiresome while on long rides. However, having that control gives riders an upper hand in some situations, such as on difficult terrain.

While automatic bikes might be better suited for new riders because they are easier to ride, most seasoned riders confess that manuals are more fun to drive overall.

Safety

When compared to most manual dirt bikes, automatic bikes do not accelerate as quickly, do not reach the same high speeds, and are not as difficult to drive, making them the safer choice. Furthermore, accidents are often not as catastrophic because of their lightweight design and slower speeds.

That being said, both automatic and manual bikes are motor vehicles that should be operated with care and riders should wear the recommended safety gear regardless of which bike they are driving.

Manual or Automatic: Pros and Cons of Each

Knowing the differences between the two engine types can help you decide which one you might find better suited for you or your family. However, if you are still on the fence about which bike to buy, knowing the pros and cons of each vehicle might make your decision a bit easier.

Manual Dirt Bike

As the name suggests, a manual dirt bike has a manual transmission. The gears that make up the transmission are controlled using a clutch, typically found on the left handlebar, and a foot lever, found by the rider’s left foot. Riders must learn how and when to activate both to drive the vehicle.

Pros of a Manual Dirt Bike

• Fast acceleration
• Better control is certain situations, such as rough terrain
• Cheaper and easier to fix due to fewer moving parts and no computer system
• Built for performance
• Faster overall speed
• Better for racing
• Larger – making them better suited for adults
• More fuel-efficient than an automatic bike

Cons of a Manual Dirt Bike

• Harder to learn how to drive
• More expensive to buy than automatic bikes
• Heavy
• More dangerous to ride
• Typically, not suitable for children or young/small riders

Automatic Dirt Bike

As the name suggests, an automatic dirt bike has an automatic transmission. Riders can find both fully automatic bikes and semi-automatic bikes, with the difference being to what extent the process of changing gears is automated. Fully automatic bikes are typically smaller and less powerful than manual dirt bikes and are a desirable choice for new riders and children.

Pros of an Automatic Dirt Bike

• Easier to learn how to ride and use
• Better suited for long rides
• Better suited for small/young riders
• Easier to control
• Less chance of breaking something in the engine while learning to ride
• Safer than manual bikes
• Cheaper to buy
• More versatile – can be used in a wide range of settings

Cons of an Automatic Dirt Bike

• Less acceleration power than a manual bike
• More moving parts in the transmission = more things that could break
• Less fun to drive
• Less performance
• More expensive to fix and maintain
• Less fuel-efficient
• Not as popular/hard to find in larger sizes

Should I Buy an Automatic Dirt Bike?

The choice between an automatic or a manual dirt bike comes down to what you want from your bike. If you are a seasoned rider who loves the challenge and performance that only a manual bike can offer, then you would probably be bored with an automatic bike. However, if you are a new rider, or do not feel comfortable with a large heavy bike, then an automatic bike might be a better choice for you.

Sum Up

Whether you choose an automatic or manual dirt bike ultimately depends on your riding experience, skill level, and personal preferences. While automatic dirt bikes are easier to ride and less expensive, manual dirt bikes offer greater control and a more immersive riding experience.

The post Rev Up Your Knowledge: Are Dirt Bikes Automatic or Manual? appeared first on ATVFixed.com.

Imagine ripping down a forest trail. Mud flying behind you as the wind whips past your ears. Freedom, control, and you alone with your thoughts. Although humans are social creatures, we need time to ourselves now and then to recharge our batteries.

Being able to hop on our machines and enjoy the solitude of a sun-splashed trail is arguably one of the best things about owning a bike, but should you ride a dirt bike alone?

Although riding alone is dangerous, riding alone unprepared is much worse. When going out alone, riders should pack extra essential gear, carry a cell phone with tracking capabilities, and tell someone exactly where they plan to ride.

Continue reading to learn more about riding alone, the most common riding injuries, and how to make your solo trip slightly safer.

Are Dirt Bikes Dangerous?

Dirt bikes can be dangerous, especially if the rider is inexperienced or ill-prepared. In fact, according to a 2006 study released by the CDC, an estimated 56,870 people were treated in a United States emergency room for injuries resulting from off-road motorcycle crashes in 2003, and at least 245 of those people died from their injuries.

Safety gear, or a lack of it, is one of the biggest contributing factors in dirt bike fatalities, and many riders simply do not take the precautions that they should while riding a dirt bike. For example, one 2010 study estimated that as many as 60% of dirt bike-related deaths resulted from riders not wearing a helmet.

This became a focus for many public health agencies around 2007 when dirt bike-related fatalities peaked, and many agencies began creating safety campaigns targeting younger riders. Since then, the number of injuries has steadily declined each year, but they are still high enough to remind us that dirt bikes can be dangerous machines.

What Are The Most Common Dirt Bike Injuries

Although quite a lot of research has been done to analyze the prevalence of injury for dirt bike riders, extraordinarily little research has been done on the exact nature of these injuries. The research that is available is a bit flawed because it only includes the injuries for which medical attention was sought and does not include those injuries that people treated themselves at home.

One of the most comprehensive studies done was a study published in 2004, which looked at the incident of injuries over a 12-year period. The authors looked at 1500 accidents, and this is what they found.

• Bruises were one of the most common injuries
• 50.9% of fractures occurred in the upper extremities, 38% in the lower, and the rest were to the spine, chest, and skull.
• 5.8% of spine fractures resulted in permanent neurological damage.
• 5.7% of the accidents resulted in head trauma, and 3% of these resulted in a coma.
• 60% of limb injuries were on the left side.

Below you can find a list of some of the most common injuries that dirt bike riders sustain, along with a link to first-aid sites for these injuries to help you better prepare for your solo ride.

Preventing Dirt Bike Injuries and Accidents

Technique and safety gear—are the two most important things when it comes to preventing dirt bike-related injuries.

Knowing how to use the machine is important, but your riding technique is what will keep you safe. You must understand how your bike works, how it moves, how it will react to different situations, and when not to push it.

However, riding technique is not all about skill; even the most skilled riders will get into trouble if they act irresponsibly. If your friend’s bike is too powerful for you, do not ride it. If you are drinking, do not get on a bike. Knowing your limits is just as important as knowing the limits of your bike.

If accidents were always avoidable, they would not exist, which is why it is important to have the right safety gear. Although you might have different equipment for different riding scenarios, you should always have a helmet, boots, goggles, chest plate, and protective clothing.

Additional gear, such as elbow pads, shin guards, and knee braces, can further protect you from some of the most common injuries. Neck braces might help prevent spinal injury, but some professionals have said they may actually do more harm than good.

Safety Gear Checklist for Riders

• Helmet
• Riding Boots
• Goggles
• Knee Brace
• Neck Brace
• Chest Plate
• Elbow Guards
• Shin Guard
• Dirt Bike Pants and Shirt (Jersey)
• Gloves

Tips For Riding Solo

Although riding alone is not highly recommended, following the steps below can help ensure your safety if you decide to venture out alone.

1. Check Your Bike

The last thing you want to do is break down in the middle of a trail. Checking your bike before taking it out can help prevent this. Also, checking the brakes and lights can help you avoid unnecessary accidents.

2. Bring Some Essential Tools

While loading yourself down with weight is not ideal, there are a few things that you should bring when riding alone. Make sure to bring enough gas, spare tubes, and patches for the tires, a small air pump, and any essential tools you might need to repair common issues.

3. Pack a Bag

Again, carrying a lot of stuff is not ideal, but bringing a small pack with you is essential when riding alone. Some of the things that you should bring with you include:

• Water
• Food
• Phone
• GPS Tracker
• First-Aid Kit
• Lighter or Fire Source
• Map
• Space Blanket
• Poncho
• Waterproof Bag
• Wallet/ID/Money

Basically, you should pack anything you might need if you break down, become stranded, or crash. Make sure you have some way to communicate with help and that you always keep it on you.

4. Map Out Your Trail

Adventuring off the beaten trail can be fun sometimes but should not be done while biking alone. Instead, you should research the trails beforehand, mapping out the route you plan to take. Include those in your plans if you want to check out a few different trails.

This is important for a few reasons. First, it allows you to let someone know exactly where you can be found. Second, it will help prevent you from becoming lost. Finally, it allows you to research the trails in a bit more depth to better prepare yourself for the terrain you will encounter.

5. Check the Weather

If you are planning a ride in an unknown territory, it is a clever idea to check the weather forecast for the entire day. Heavy rain could cause water levels to rise, and humid weather could cause heatstroke. Even a slight drizzle can change the trail you are riding on, so make sure you are prepared for any weather you might meet.

6. Tell Someone Your Plans

Even if you are just going for a quick jaunt in your backyard trail, tell someone where you are going and how long you plan to be gone. The last thing you want to do is spend the night injured in the woods because nobody knows where you are.

This is also when having a tracking device can come in handy because if you do not return on time, they can quickly find your location and check in on you. Keep your phone or communication device in an easily accessible place on your person so you can always reach it.

7. Know Your Limits

It is not a good idea to try a new jump or try to beat your high speed while riding by yourself. If you find yourself doubting or second-guessing a decision, stop and think it through more critically. The new trail might look like a fun adventure, but it could lead you off the side of a cliff. Being reckless with your friends is one thing; being reckless while riding alone is asking for trouble.

Sum Up

While riding a dirt bike alone can be exciting, it’s important to consider the potential risks and safety measures. Riding with a partner or group can provide additional safety and support, but if you decide to ride alone, inform someone of your plans, carry necessary safety gear and tools, and ride safely within your skill level.

The post 7 Safety Tips for Riding a Dirt Bike Alone appeared first on ATVFixed.com.

Whether you are looking for a way to get your child to unplug and spend more time outdoors or want to break into the world of motocross, there are many great reasons to buy an off-road vehicle. However, after deciding to buy an off-road machine, many people find themselves asking this age-old question, “Should I buy a dirt bike or a quad?”

If safety, price, and adrenalin are your main concerns, you might want to buy a dirt bike. Alternatively, if functionality and comfort are a top priority, a quad might be better suited for you.

Because dirt bikes and quads differ quite dramatically, it is important for shoppers to know what they want in a machine before deciding which one to buy. Keep reading to learn more about each off-road vehicle to help you decide which one is right for you.

What is a Dirt Bike?

According to the Oxford Dictionary, a dirt bike is “a motorcycle designed for use on rough terrains, such as unsurfaced roads or tracks, and used especially in scrambling,” but what separates a dirt bike from a motorcycle?

The biggest difference between a motorcycle and a dirt bike is weight and equipment. Dirt bikes are typically more lightweight, and they are not held to the same legal standards as a motorcycle. Although they can be equipped with these items (and they may be required for certain sports use), they are not required to have things like brake lights, headlights, and mirrors. The downside to this is that they are not able to be licensed and driven on main roadways.

Like motorcycles, there are different types of dirt bikes and which one you own will depend on what you want to do with the bike. For example, motocross dirt bikes have larger engines and are better equipped to handle jumps and corners, while a trail bike is better suited for longer rides.

What is a Quad?

According to the American National Standards Institute, a quad is defined as a vehicle that travels on low-pressure tires, with handles bars that control steering and a seat that is straddled by riders. You might have noticed that this also describes many other All Terrain Vehicles, so what separates a quad from other ATVs?

A quad is an ATV, but not all ATVs are quads—does that make sense? It may seem confusing at first, but the easiest way to identify a quad vehicle is to count the tires. The acronym “ATV” is an umbrella term that encompasses several types of vehicles, and those vehicles can have anywhere from two to four wheels. Quads are ATVs that have four wheels.

In addition to wheels, quads are typically used for more recreational, off-road activities. Many larger ATVs can be used for heavy-duty work purposes, or to carry passengers, while a quad is typically reserved for smaller jobs, fun, and typically only seats one or two people.

What Can I Do with a Dirt Bike?

If you are struggling to decide which type of off-road vehicle you would rather buy, it might help you to think about what you want to do with the vehicle.

There are many reasons why people fall in love with dirt bike riding. It offers people a sense of freedom and can be a fantastic way for younger people to get moving without needing a road license. Additionally, riding can be an effective way to sharpen your focus, improve your physical health, and tap into a tight social circle.

Even though they are not road legal, there are a lot of ways in which dirt bikes can be used. People of all ages can use these lightweight bikes to bomb around the yard with friends, explore thousands of miles of trail, or enter competitive motocross racing.

This sport attracts a lot of diverse people because there are so many ways to use a dirt bike. From the adventurist looking for a lazy ride through a local forest to the adrenaline junkie looking for the next big jump, almost everyone can find an activity they love doing with a dirt bike.

What Can I Do with a Quad?

Just like dirt bikes, there are many great reasons why quad enthusiasts fall in love with their machine, but it might surprise you to learn how differently each of these vehicles can be used.

Just like a dirt bike, there are many fun ways to use a quad. They too can be used for jumping and racing, although admittedly, dirt bikes have the upper hand in this category. Still, several young riders spend their weekends racing through the backwoods trails and getting stuck in deep mud puddles with their quads.

While dirt bikes might be better for competitive use, quads have the upper hand in leisurely riding. Although it is possible to take a dirt bike on a day trip through the trails, quads are better equipped for this. They can haul more gear and offer more comfort during a long ride.

One of the things that a quad offers that a dirt bike does not is utility. Quads can be used for household or work-related chores, and they are often used on farms and other outdoor job sites. People often use quad vehicles for landscaping chores, to haul heavy items, to move things around their property, to tow things, and for snow removal.

While we are sure it has been done somewhere, attaching a snowplow to a dirt bike would be quite difficult.

Reasons to Get a Dirt Bike

Safety

If asked which machine was safer, most people would say that quads are safer, but most people would be wrong. At least according to a study done by Johns Hopkins Medicine. In the study, it was concluded that crashes involving ATVs were often more dangerous than crashes involving dirt bikes, with those involved in an ATV accident being 50% more likely to die from their injuries.

The reasons for this are not exactly known, but researchers hypothesize that it might have something to do with the fact that 60% of bike riders in the study were wearing helmets compared to only 30% of ATV riders. In addition, quads are heavier than dirt bikes and result in worse injury when landing on the rider.

Finally, it might also be because riders believe they are safer and so they drive more recklessly. Whatever the reason, if you are looking for the safer option, you might be surprised to learn that two wheels are safer than four.

Price

In addition to being safer, dirt bikes are often less expensive. Since bikes are smaller, have fewer features, and use fewer materials when being manufactured, they typically come with a lower price tag.

While prices range dramatically depending on what type of bike you are looking for, riders can usually find a new bike for between $3,000 and $8,000. On the other hand, riders in the market for a quad are looking at a price tag between $5000 – $15,000. Furthermore, the cost of maintaining a dirt bike is much less costly than the cost of maintaining a quad.

Sport

Both dirt bikes and quads can be used for racing. However, dirt bikes are typically better suited for racing because of their higher speeds and maneuverability. Additionally, bikes are lighter than ATVs, making them better equipped for tricks and landings.

Socializing

Both machines offer a terrific way to socialize with friends. They can both be ridden with friends, and it is common to see large groups on day outings with both machines. However, dirt bikes tend to have a bigger circle of riders, and many people enjoy being a part of the motocross community.

Adrenaline

Dirt bikes tend to offer more of an adrenaline rush than quads because they are more difficult to ride. Riders must stay focused and ensure their body is moving with the machine in perfect unison. While quads offer more leisurely riding, dirt bike riders are constantly assessing the situation and making quick decisions. Plus, they are usually much faster than a quad.

Functionality

Although quads are more functional in terms of chores, dirt bikes are more functional in terms of storage. They are lighter than quads, which makes them easier to haul and store.

Fuel-Efficient

In addition to a lower price tag, dirt bikes are more fuel-efficient, which is yet another way that they are less expensive than quads. The reason for this is their lightweight design and less powerful engines. However, it is important to note that some of the bigger bikes, including motocross bikes, may not be as fuel-efficient as the smaller bikes.

Reasons to Get a Quad

Ease of Use

Do you remember the first time you took the training wheels off of your bicycle? You probably felt unbalanced and found yourself falling once or twice. Learning to ride a dirt bike is similar, and it can take months before an individual becomes confident on a bike. Quads, on the other hand, can be driven almost at once and often require little beyond the push of a throttle button. That being said, please remember that they are still dangerous and should be driven with care.

Functionality

When it comes to functionality, quads are the better choice and if you are looking for a machine that can provide fun on the weekends and help with chores during the week, you may want to get a quad.

Environment

Most quads are designed to be driven in a variety of conditions, while dirt bikes are a bit more limited in terms of the environment in which they can be driven. For example, most dirt bikes are not suitable for winter conditions, while quads can be equipped with snow tires. Furthermore, quads can be equipped with accessories that allow them to plow and move snow.

Comfort

It may seem obvious, but quads are much more comfortable than dirt bikes—especially during long trail rides. Bikes require a lot of physical core strength from riders, while quads basically require riders to simply sit on and steer the machine. Additionally, quads are typically designed with features that make day trips more comfortable. For example, they have more comfortable seats, may have a backrest, and have room to store things.

Longevity

Although dirt bikes are cheaper, quads tend to last longer. While a well-cared-for dirt bike should last between three and five years, a well-cared-for quad should last riders upwards of 10 years. Of course, this depends on how the machines are driven and maintained, but on average, quads will last longer.

Seating

Dirt bikes are designed for one rider, and although many quads are also made for just one rider, it is possible to find quads that can seat more than one person. This is important if you are looking for a machine that you can ride with a partner.

Comparing The Pros and Cons

There are many good reasons to buy both machines, which makes the decision all that much harder. However, to avoid making the wrong choice, shoppers should weigh the pros and cons of each vehicle and compare them against their needs.

Pros and Cons

Should I Buy a Dirt Bike or a Quad

When trying to decide between a dirt bike or quad, shoppers should think critically about what they want from their new toy. For example, it would not make sense for someone who wants a machine they can use to explore trails with their spouse to buy a dirt bike, just like it would not make sense for someone who wants to break into competitive racing to buy a quad.

Before shopping, sit down and make a list of what you want to do with your machine and compare it to the pros and cons list above to figure out which one would work better for you.

Riding is a great way to unwind after a long week and explore rural areas. However, you will have to buy a bike before you can start ripping up the trails. Like any vehicle, one of the first decisions you will have to make is whether to buy a new or used and each way has its pros and cons.

This article will break down the pros and cons of each choice to help you decide—should I buy a new dirt bike?

Riders who plan to use the bike a lot or competitively may want to buy a new bike. However, first-time riders or those who do not plan to use the bike a lot may save themselves a lot of money by buying a used bike.

Continue reading to learn about the pros and cons of buying a new dirt bike and whether buying a new one is a good idea for you.

How Much Does a New Dirt Bike Cost?

The price of a new dirt bike will vary depending on what type of bike you are buying, the size of the bike, and where you buy the bike. However, the average shopper will spend between $4,000 and $9,000 on a new dirt bike.

Below you can find a list of some of the most popular bikes on the market today along with their prices.

How Much Does a Used Dirt Bike Cost?

While it is a bit harder to pinpoint the average price of a used dirt bike, we can say that most bikes depreciate around $1000 a year. So, if you were looking for a bike that was around two or three years old, you would expect to spend between $1,000 and $6,000. However, this depends on how well the bike was maintained as well, as a three-year-old bike that was only driven a handful of times will cost much more than a three-year-old bike that was used in competitive sports.

The list below contains prices of actual used dirt bikes for sale online (2022). Additionally, we looked up the price of each one in 2022.

Why Are Some Used Dirt Bikes So Expensive?

The Covid pandemic has caused many changes in the world, but one of the weirdest side effects is how it has affected vehicle sales. Because of glitches in the supply chain, and the fact that many manufacturers were contracted to make other supplies, newer model vehicles are in short supply.

However, demand is still high, which has led many people to buy used products, which has caused sellers to raise their prices significantly. For this reason, buying a used dirt bike might cost you almost as much as buying a new one, so it is important to do your research before buying a used to ensure you are not getting a lesser-value vehicle for the same amount of money.

Pros and Cons of Buying a New Dirt Bike

Pros

• Clean Slate: Buying a brand-new bike gives riders the mental relief of knowing that they will have a while before any significant problems pop up. Whereas when you buy used, you could end up needing to make a major repair tomorrow.
• Build: When you buy a new bike, you are in control. You get to choose which options, add-ons, and features you would like to add to the bike. While this will cost you more, it can be a terrific way to build the bike of your dreams.
• Warranty: Most new bikes will be covered under some time of manufacturer or dealer warranty. However, most warranties are only valid for the original owner and therefore, even if you buy a used bike while it is technically still within the warranty period, it may be void because you are not the original owner.

Cons

• Expense: As with anything, you will pay more for a brand-new bike. However, with the recent pandemic skyrocketing the price of used vehicles, this may not be as close to the truth as it once was. In fact, there are several bikes listed on Cycletrader right now that are priced higher than they retail for brand new. Still, on average, riders can save a few thousand dollars buying a used vehicle.
• Supply: Speaking of inflation, the reason that used prices have risen so dramatically in the past couple of years is due to the supply of newer vehicles being slim. If you have your heart set on a specific model, it may be hard to find that model new.
• Damage: If you are just learning to ride, or just want something to beat around, buying used might not be a smart choice. New riders are bound to fall, which means they are bound to scratch, scuff, dent, or otherwise damage their bike. Although you will likely have a warranty, it may not cover damage caused by wear and tear.

Should I Buy a New Dirt Bike?

At the end of the day, the decision to buy a new or used bike will depend on you and your needs.

Who Should Buy New?

• People who have the money to invest in a new machine or have been saving up to build the bike they have always wanted.
• People who can afford to make payments each month.
• Experienced riders who have been riding long enough to know the best way to care for a machine.
• People who can afford, and will remember, to maintain the bike according to schedule.
• People who plan to ride competitively and need a good reliable bike.

Who Should Buy Used?

• People who do not really care about the make and model of the bike and just want something that runs.
• People living on a budget who cannot afford the price tag that comes in a brand-new bike.
• People who do not want to get into a payment plan and would rather buy something outright.
• People who are just learning to ride and may potentially damage the vehicle while learning.
• People who want a certain make or model and cannot find it in stock.

Sum Up

Buying a dirt bike can be a great investment for those who enjoy off-road riding, but it is important to carefully evaluate your needs and options before making a purchase. With the right research and preparation, you can find a dirt bike that is safe, reliable, and fun to ride.

• Evaluate your riding experience level and skillset to determine if a new dirt bike is right for you.
• Consider your budget and financing options, as dirt bikes can be expensive.
• Research the different types of dirt bikes available, including motocross, trail, and dual-sport.
• Determine the size and engine displacement that will best suit your needs and preferences.
• Test ride multiple dirt bikes before making a final purchase decision.
• Consider the maintenance and repair costs associated with owning a dirt bike.
• Take safety precautions seriously and invest in proper gear, such as a helmet, boots, and protective clothing.
• Understand the laws and regulations regarding dirt bike usage in your area.
• If you are a beginner, consider taking a dirt bike training course to improve your skills and gain confidence.
• Consider purchasing a used dirt bike to save money, but ensure that it is in good condition before making the purchase.

No fuel equals no fun. Not to worry, as dirt bike problems go, a lack of gas flow is one of the easier and cheaper ones to fix. You are in the right place, I’m a mechanic with twenty-five years experience and I’ll bet you’ll be riding shortly.

The top six causes of a lack of dirt bike gas flow include:

1. Blocked tank vent
2. Blocked gas filter
3. Blocked gas tank
4. Carburetor adjustment needed
5. Faulty fuel pump
6. Mechanical issue

In this post, you’ll all the common reasons a dirt bike isn’t getting fuel. You’ll learn how to diagnose your problem and how to fix it right now.

Dirt Bike Fuel System Types

Before we get into the diagnosis of the root cause of no gas flow it’s important to know which type of fuel system your bike has, not all dirt bike fuel systems are identical.

Dirt bike fuel systems come in two flavors:

1 – Computer controlled fuel injected system

2 – Carburetor gravity feed fuel system

Because these systems are similar but not identical, the possible causes of no gas flow are also slightly different in places.

What’s the difference between the two fuel systems?

Both systems employ some similar components:

Carburetor Gravity Feed System – These types of fuel systems are typically in all older bikes and employ a mechanical carburetor that mixes air with gas. The gas is fed to the carburetor from the gas tank using only gravity. And that gas is held in the carburetor gas bowl (reservoir) and stands ready to feed the engine as needed.

Fuel Injected System – This type of system as you know employs some of the same components as a carburetor type but it is a way more sophisticated system. It employs sensors, solenoids, motors, and a computer to mix air and fuel and delivery it to the intake system. Some dirt bikes may require a battery to run the fuel-injected system and others don’t.

It’s a pressurized system and uses an integrated gas tank fuel pump to both move the gas from the gas tank quickly and to pressurize it.

How to identify which type you have?

Not always that easy to spot the difference without removing some covers and components. Often it’s better to check your owner’s manual or google search your model.

Diagnosis No Gas Flow

Now we’ll get down to the nuts and bolts of diagnosing where your fault lies. We’ll run through each of the likely no-fuel causes and I’ll indicate in advance if it’s applicable to carburetor or fuel injected or both type systems.

We’ll run through all the easy-to-check likely causes first, no sense removing seats and covers unless we need to.

Blocked gas tank vent (both carburetor and fuel injected)

Gas tanks need to breathe, meaning as the gas leaves the tank it must be displaced by air otherwise the flow of gas stops. This is true for both carburetor and fuel-injected systems. As you know the tank is vented through the gas tank gas cap and attached hose.

Diagnosis – We start with this test as it’s likely the easiest test of all. Gas caps get lost and are sometimes replaced with a makeshift cap and for many, that’s where the problem begins.

The gas tank vent could equally be at fault so to eliminate both the gas cap and the vent hose from the list, go ahead and remove the gas cap and attempt to start the bike. If gas now flows to the engine, you found your problem.

The fix – Replace the gas cap and vent hose.

Blocked gas filter (both carburetor and fuel injected)

Gas filters are fitted inline, some at the gas tank others may be carburetor integrated. A filter’s job is to catch the debris in the gas tank and prevent it from reaching the engine’s intake system. Gas filters should be replaced or cleaned once a year, many aren’t.

Diagnosis – Locate the gas filter and check for debris. Clear inline filters are the easiest to check. Removing the fuel line downstream of the filter (carburetor side) and checking flow is a fast way to eliminate a filter issue.

The fix – Clean or replace the gas filter. When replacing clear bottle gas filters, the filter arrow points to the carburetor.

Blocked gas tank (both carburetor and fuel injected)

A blocked gas tank isn’t hugely common anymore, plastic tanks have removed the corrosion issue associated with metal tanks. That said, a poor flow from the tank may well be caused by a tank blockage. Re-gas from contaminated refill cans can easily introduce debris.

Diagnosis – Removing the gas cap and peering in likely won’t reveal much. The best approach is to remove the gas line at the gas tank and check flow. A poor flow means you’ve found your issue.

The fix – If you suspect tank blockage, you’ll need to remove the tank to clean it thoroughly. That will mean removing the seat, side covers and removing the gas lines and tank fasteners. Once removed, turning the tank upside down will remove the debris. Rinse out using fresh gas.

Carburetor adjustment needed (carburetor)

A fuel starvation issue may be caused by a maladjusted carburetor float. The float’s job is to help control and maintain gas flow in the carburetor bowl. As its name suggests the float floats on the fuel inside the fuel bowl. The bowl is a reservoir of gas that stands ready to feed the engine.

As the engine uses gas, the float drops which allows more gas to flow in to replenish the spent gas. If the float tab is set too high, the bowl won’t fill.

Diagnosis – Remove the gas bowl and check the float level. You’ll need a caliper and the float spec for your engine.

The fix – Adjust or replace the float and valve needle.

Faulty fuel pump (fuel injected)

A fuel-injected system employs a gas pump located inside the fuel tank. Its job is to pressurize the gas and move it to the engine. Fuel pumps work hard and do fail a lot. A failed pump is for some easy to identify as a fuel pump emits a buzzing noise when in operation. That said it is possible for a fuel pump to emit a buzzing noise but not build sufficient pressure to feed the engine.

Diagnosis – To test a fuel pump thoroughly we’ll need to check fuel pressure and to do that we’ll need a fuel pressure test kit. A good pump will typically build pressure in the region of 45psi.

There are still some tests we can do without a fuel pressure test kit but we will need a DVOM. We can check pump resistance and to do that we’ll need to access the gas tank. That will mean removing the seat, side covers, and air intake.

Test fuel pump resistance gain accesses to the injector and check the electrical connector is secure. Now go ahead and remove the connector and set it aside. Using the DVOM set to ohms (Resistance) probe both terminals gently and note the meter reading of about 6 ohms works. If you measure excessive resistance or open, you found your problem.

The fix – Replacing the pump isn’t difficult, You will need to be careful when removing the fuel line connector, often brittle and when fitting the new pump the O-ring seal will require some oil.

Fuel injector faulty (fuel injected)

The fuel-injected system employs a fuel injector to spray a fine mist of fuel into the intake system, without the injector activating we won’t get fuel to the cylinder. To test the injector, we can check it for resistance, and do that we’ll need a DVOM.

Diagnosis – Access the injector and check the electrical connector is secure. Now go ahead and remove the connector and set it aside. Using the DVOM set to ohms (Resistance) probe both terminals gently and note the meter reading.

A reading of about 12 ohms indicates a good injector, outside this, and you’ve found your fault.

The fix – Replacing an injector is a simple process. Remove the electrical connector, fuel line a couple of fasteners, and it off. When replacing the injector, lube the O-ring to aid fitting.

Mechanical faults (carburetor)

Since a gravity-fed fuel system relies on gravity and engine vacuum to draw gas into the engine, compression, therefore, may cause a fuel flow issue. A lack of compression to most engine owners sets alarm bells, but it should be noted not all low compression issues are serious.

Common non-terminal low compression issues include:

• Valve adjustment required
• Loose spark plug
• Head gasket leak
• Valve seat wear

Diagnosis – I’ve covered compression issues and testing previously and you can check that post, right here “Dirt bike with low compression”

Springtime is a fun time, or at least it was until you discovered your favorite toy didn’t make it through hibernation. Don’t worry about it. This is a common complaint, and as a mechanic, I see it a lot at this time of the year. This is something we can fix right now, and very shortly, you’ll have a big smile on your face!

A dirt bike that won’t start after winter likely suffers from stale gas and carburetor contamination. Draining the old gas, draining the carburetor bowl, and refilling with fresh gas will solve the problem.

In this post, you’ll learn why your dirt bike won’t start and what you need to do to fix it right now. I’ll also share some top tips for dirt bike storage.

Problem With Gas, Dirt Bikes & Winter Storage

The problem most commonly associated with dirt bike winter storage is stale gas. The problem is modern gas contains ethanol (E5 and E10), and ethanol gas begins to turn stale after about two months, but this varies depending on ambient conditions and how much exposure to the atmosphere.

In addition, ethanol attracts moisture which causes all types of carburetor issues.

Unlike modern cars and trucks, small engine kit such as dirt bikes employs an open-to-atmosphere gas tank. This allows the tank to breathe, which is crucial for fuel flow.

On the other hand, modern cars and trucks use sophisticated modules and valves that allow for a sealed gas tank. The advantage to a sealed gas tank is twofold; it protects the environment from harmful vented hydrocarbons and, at the same time, prevents moisture from entering the tank.

This moisture causes dirt bike fuel problems over the winter months.

How To Diagnose Dirt Bike Stale Gas

If your dirt bike has been sitting with gas in the tank over winter and that gas hasn’t been treated with a gas stabilizer, then you can be sure your gas is stale. To check, try removing a sample in a glass jar. Stale gas looks the color of pee. Still not sure?

Try the gas shot test. This test bypasses the fuel system and adds fresh gas direct to the cylinder.

To perform the gas shot, use the following steps:

• Remove the spark plug
• Add a capful of fresh gas to the cylinder
• Refit the plug
• Attempt to start the engine

Diagnosing the results

Two results are likely:

1 Engine starts or attempts to fire – Fires may be described as an engine that doesn’t start but tries to. You’ll know an engine that fires as it will puff smoke from the tailpipe as it tries to start. Under these test conditions, such an engine likely suffers from stale gas.

2 Engine makes no attempt to start – Likely an ignition system issue (lack of spark). I wrote a post about ignition system testing, and you can check that out here “Dirt bike won’t start when hot”

How To Drain Dirt Bike Stale Gas

In the workshop, I use a siphon to drain the gas tank, but removing the carburetor fuel feed line works too. Using a siphon is, however a ton easier; they only cost a few dollars, and a good siphon will lift oil, brake fluid, coolant, etc., so you’ll find a ton of uses.

To drain a gas tank using a siphon, open the gas tank cap, place the siphon tube into the gas tank, and pump the siphon. Easy!

Or remove the gas line to drain it manually.

To drain the tank manually, you’ll need a gas line clamp and a suitable container. Gas stinks; it’s best to drain the gas tank outdoors.

The draining process is as follows:

• Turn off fuel valve
• Remove gas cap
• Remove the gas line from the carburetor and place it in the container
• Turn the gas valve on and drain the tank

Most recycling centers will accept waste gas and oil.

After the tank has been drained, you’ll need to drain the carburetor bowl, which we’ll cover next.

Draining Dirt Bike Carburetor

All dirt bike carburetors employ a carburetor bowl. The bowl is a reservoir where gas and often dirt collects; draining the bowl helps clean the fuel system of contaminated gas.

The process is as follows:

• Turn the gas valve off
• Remove gas tank cap
• Gain access to the carburetor
• Located the carburetor bowl
• Locate the carburetor bowl drain fastener known as the bung (usually a small drain screw in the bowl base)
• Place rag under the carb bowl and open bung
• Open the fuel valve and add a small amount of fresh gas to the empty tank to help flush out the carburetor bowl
• Close the bowl bung

Top Tips For Dirt Bike Winter Storage

A dirt bike that’s stored correctly will start without issue come spring. Proper storage isn’t difficult and it requires little effort or expense.

Here are my top dirt bike storage tips:

• Change engine oil (4-stroke engine) – Removes internal engine moisture and acidic contaminants
• Use gas stabilizer in the fuel tank – See below
• Fill gas tank – Helps prevent condensation on inner tank walls
• Clean and oil air filter – Prevents trapped moisture and rodents
• Turn the gas valve off – Takes fuel pressure off the float and valve
• Inflate tires – Helps seal and protect tire walls
• Add oil capful engine oil to the cylinder – See below
• Set engine to top dead center (TDC) – See below
• Seal exhaust – Stuff tailpipe outlet with an old rag or plastic bag
• Remove chain – Remove the chain and seal it in a plastic bag with some oil
• Lift bike – Support chassis to lift tires clear of the ground
• Protect metal – Spray bike thoroughly (not rotors or pads) with WD40 or use Teflon coating (guards against corrosion)
• Rodent bait – Rodents love to eat wiring insulation
• Store indoors – Overwintering indoors is critical
• Breathable cover – A breathable cover keeps moisture trapping dust and dirt off the bike while allowing the bike to breathe.

Use gas stabilizer in the fuel tank

The gas stabilizer is specially formulated to repel moisture and keep ethanol gas fresh for up to twelve months. The gas stabilizer is strongly advised for your dirt bike; in fact, use it in all small engines, ATVs, Outboard motors, Tractor mowers, Chainsaws, etc.

The gas stabilizer is not a substitute for a two-stroke mix, so if your dirt bike is a two-stroke mix as usual then add the gas stabilizer. Mixing is easy; your gas stabilizer will recommend the mixing ratio.

A common ratio is 1/2 ounce stabilizer (about a tablespoon full) to every gallon of gas. Ride the bike about to help distribute the mixed gas throughout the fuel system. That’s it; your bike’s carburetor is protected from winter gumming.

Add engine oil to the cylinder

I like to add a capful of engine oil to the cylinder. Oil in the cylinder helps protect the walls from corrosion. The process is as follows:

• Remove the spark plug
• Use a syringe or funnel to add a capful of fresh engine oil to the cylinder
• Turn engine over to distribute oil

Set engine to top dead center (TDC)

Setting the engine to Top Dead Center closes the valves and seals the cylinder, which helps protect the engine cylinder walls from moisture and prevents sticking valves.

To set the engine to Top Dead Center (TDC), follow these steps:

• Remove spark plug
• Place a suitable non-metallic object into the cylinder to make contact with the piston crown (a pencil works fine)
• Using the Kickstarter or socket and ratchet, turn the engine over slowly so as to push the pencil from the engine
• When the pencil is pushed to it’s max from the cylinder, the engine is set to TDC
• Refit plug

Sum Up

It’s frustrating when you’re ready to hit the dirt trails on your dirt bike after a long winter, only to find that your bike won’t start.

If your dirt bike doesn’t start after sitting for a while, there are several steps you can take to troubleshoot the issue. From checking the battery and fuel to inspecting the spark plug and air filter, you can usually identify and fix the problem on your own.

Here are some steps you can take to troubleshoot the issue:

• Check the battery: If your bike has been sitting for a while, the battery may be dead. Charge it fully or replace it if necessary.
• Check the fuel: Drain the old fuel and replace it with fresh fuel. Stale fuel can cause your bike to have starting issues.
• Check the spark plug: A worn or fouled spark plug can also cause your bike to have starting problems. Remove and inspect the spark plug and replace it if necessary.
• Check the air filter: A dirty air filter can also cause starting issues. Remove and clean or replace the air filter if necessary.
• Check the carburetor: The carburetor may need cleaning if the bike has been sitting for a while. If you’re not comfortable doing it yourself, take it to a mechanic.
• Check the fuel lines: Ensure that the fuel lines are clear and not clogged with debris or dirt.
• Check the ignition switch: Make sure the ignition switch is turned on and functioning properly.
• Check the choke: Use the choke to help start the engine, but be sure to turn it off once the bike is running.
• Check for other mechanical issues: If none of the above steps work, there may be other mechanical issues causing your bike not to start. Take it to a mechanic for a diagnosis and repair.
