How to Fix a Stuck Throttle on a Dirt Bike

If your dirt bike throttle gets stuck, there’s a good chance you’re in for a world of trouble. A stuck throttle can cause the bike to overheat and even catch on fire, so it’s essential to know how to fix it quickly. In this article, we’ll show you how to fix a stuck throttle on a dirt bike using a few simple techniques. We’ll also cover some common causes of this problem and how to prevent it from happening in the future. So read on to learn more!

Many dirt bikes suffer from a stuck throttle at some point, but if you take your bike to a great mechanic, it can be easily fixed without too much trouble. However, sometimes dirt bikes get stuck throttles because of dirt and debris caught in the carburetor’s slide assembly. If the debris is not removed by a professional, it will eventually cause problems, including a stuck throttle.

Summary: First, see if the throttle is stuck by trying to move it from side to side. If it’s moving freely, the issue may be with the cable or linkage connecting the throttle to the engine. If the throttle is physically stuck, you may need to remove the carburetor or air filter to get to the throttle cable. Sometimes lubricating the cable and adjusting the throttle linkage will fix the issue.

What Causes the Throttle to Stick?

Sticking throttles are a common problem on dirt bikes. Many different factors can cause a sticking throttle, but the primary cause is a loss of lubrication in the cables and bearings that control the handgrip twist. Dirt, dust, and mud can all create a loose fit for cables and linkages over time.

How often you wash your bike can also contribute to this issue since not rinsing off loose dirt from previous rides will allow it to bake onto the parts until they become caked with debris.

Most dirt bikes have rubber o-rings that help keep water out of the bearings. This helps prevent rusting when riding in wet conditions.

If you ride your bike through deep puddles or in wet conditions, some water will eventually get into the bearing housings, even if there are rubber o-rings. However, if there is already dirt in the housings, the water will mix with the dirt and cause the throttle to stick.

Tools and Materials

  • Socket wrench
  • Needle nose pliers
  • Flathead screwdriver

A Step by Step Guide on How to Fix a Stuck Throttle on a Dirt Bike

Step 1: Preparation

Before one begins, the first thing you need to do is gather all of your equipment. Some of the things required for this task are a socket wrench, needle-nose pliers, and a flathead screwdriver. The first tool needed is a socket wrench because it will aid in loosening the gas cap. In addition, this process requires needle nose pliers and a flathead screwdriver.

Step 2: Removing the Gas Cap

The next step after gathering your equipment is to remove the gas cap. If the throttle is stuck, you’ll need to use a socket wrench to loosen or tighten it. However, there are two key factors to consider before removing the gas cap: whether you can turn off your bike with grip tape, and what kind of dirt bike you have. Some bikes, like KTM dirt bikes, require more pressure than others when removing the gas cap.

Step 3: Remove Throttle Tube

After removing the gas cap, remove the throttle tube. This is done by unscrewing or loosening the bolts that connect it to the grip tape. Once this has been completed, take hold of your needle nose pliers and slip them between where the rubber cover meets with the rest of your dirt bike coming in contact with both sides. Once you have correctly inserted your needle nose pliers, twist each side until it begins to come loose or becomes disconnected from its spot on either side of your bike’s body.

Step 4: Free Throttle Cable

Once you have successfully separated the throttle cable from its designated location, there are just a few more steps before being able to fix your throttle. However, it would help if you were cautious before continuing as the throttle cable is now completely loose and can be turned by hand.

Step 5: Freeing Stuck Throttle Cable

Preforms another twist of your needle nose pliers to remove the rubber covering both cables.

Remove the Rubber Covering Both Cables

Once completed, carefully pull each end of this cover off until it becomes detached from both cables. Next, slip your fingers around the casing where the rubber used to be and turn each side of your throttle until you can separate it from one another again, free of charge.

Step 6: Wipe Down Handlebar and Throttle Tube

After successfully separating the throttle tube from its housing, take a few minutes to wipe down your handlebar and throttle tube with a paper towel or rag. This will allow you to check for any signs of dirt or other unwanted particles that may have been introduced to your bike’s system during this process.

Step 7: ScotchBrite Handlebar and Throttle Tube

Once you have finished wiping down your handlebar and throttle tube, take your scotch Brite pad (or any other buffer type) and rub down the surface. Ensure that you do not overdo this part, as one does not want to scratch their dirt bike’s finish. The goal is to remove all oil or grease from the surface so that there are no barriers between your grip tape and throttle tube.

Step 8: Apply Small Amount of Grease to Throttle Tube

Once you have finished rubbing down your handlebar and throttle tube, take a small amount of grease to cover the surface before attaching it back together. This process will allow you to easily twist your throttle in the future because it creates an oil barrier between the throttle tube and grip tape.

After completing this step simply reattach one end of your throttle cable onto its designated location on either side of your dirt bike’s body. Follow up by applying another small amount of grease into both ends of the pocket that houses each end of your throttle cable.

Then slide each end through, allowing them to meet with each other where they are meant to attach. Lastly, tighten or loosen bolts until they are correctly over the top two cables, ensuring that they line up. Once this has been completed, reattach the throttle tube and gas cap before giving it a test ride.

Step 9: Test Run

After following these steps, one should have successfully fixed their throttle. It is also essential to check the fluid level of your dirt bike before taking it for a spin. This can be done by removing

the gas cap and checking underneath where your fuel line attaches to the tank. If you feel as if you are unable to fix your throttle, there are ways in which you can send out for repairs or bring your dirt bike to a professional who specializes in such matters. These steps will help in how to fix a stuck throttle on a dirt bike.

Preventing a Stuck Throttle on a Dirt Bike

Keeping Your Throttle Cable Clean

Before fixing any dirt bike throttle problems, make sure that your throttle cable is clean and oil-free. Dirt bikes are meant for adventure — which includes some seriously dusty trails. Unless you want to burn through an entire can of WD-40, keeping your dirt bike’s throttle cable clean is extremely important when preventing sticky throttles.

Lubricate The Cables

After you’ve taken the time to clean your throttle cable thoroughly, you should lubricate it for future protection. Again, standard WD-40 or a similar oil is fine if you’re in a pinch — make sure that any excess oil is wiped off after you’re done applying it.

Adjust The Cables

If your throttle is still sticky after these preventative measures, it’s probably time to adjust the cable and fix a stuck throttle. How you do this will largely depend on what kind of dirt bike

Adjust the Cable

you’re working with. If your throttle has been sticking for quite some time, you may have to turn the grip on your throttle slightly to loosen up the cables. How far you’ll need to turn it varies from one bike to another.

Check The Cable Routing

If you’re having difficulty getting your throttle to snap back into place after it has been turned, something might be wrong with the cable routing. Dirt bikes are meant for off-road riding, and that means you’ll often have to carry your bike over rocks and logs. If your throttle is sticking and you’ve already checked the cables and adjusted them accordingly, check the basic structure of your dirt bike’s frame for any visible damage or obstructions.

Inspect The Throttle Lock Or Bar Ends

If your throttle is still sticking after checking for cable routing problems and making sure the cables are clean, lubricated, and adjusted accordingly, it might be time to check out the throttle lock or bar ends. How this problem is fixed depends on what kind of dirt bike you have.

Check The Carburetor

If you can’t turn your throttle, something might be wrong with the carburetor. If this is the case, make sure that it’s properly adjusted and not plugged up before taking any additional steps to fix a stuck throttle.

Frequently Asked Questions

What Causes the Throttle Stuck in the Dirtbike?

There are a few things that you can check to try and diagnose the cause of your throttle stuck in the dirtbike. One potential problem is faulty wiring or an issue with the throttle cable. If this seems like it could be the case, then you may need to have your bike inspected by a professional mechanic.

Another common problem is dirty air filters. These should be replaced at least once per season, but if they’re not being properly cleaned, debris and dust can accumulate over time which will affect how well the engine runs. In extreme cases, this may lead to stalling or even total loss of power while on track due to clogged fuel lines or misfire issues associated with fouled plug in some cylinders.

If none of these solutions seem helpful, then it might be time for a new throttle cable or signals module. Again, having your bike serviced by a qualified technician would likely provide better results than trying DIY repairs if there’s any suspicion that something more serious is behind your trouble pistoling off-road terrain!

Should There Be Play in a Motorcycle Throttle?

many experts believe that there should be play in a motorcycle throttle. This means that the travel and resistance of the throttle should fluctuate smoothly throughout its range so that the rider can adapt their speed accordingly.

Some people argue that too much stiffness or precision will make riding difficult and tiring, while others say that without some degree of control over your speed on a bike, you run the risk of getting lost or stranded. Ultimately it is up to each individual rider to decide whether they feel comfortable with varying amounts of play in their throttles

Why Does My Throttle Not Spring Back?

If your throttle does not spring back after pressing the gas pedal, there may be a problem with the cable or the throttle body. To test the cable, remove the air filter and disconnect the negative battery cable. Disconnect the throttle cable at both ends and press the pedal to see if the cable moves. If it does not move, there is a problem with the cable. To test the throttle body, remove the air filter and disconnect both negative battery cables. Disconnect the throttle cable at both ends and press the pedal to see if it moves. If it does not move, there is a problem with the throttle body.

What Causes Throttle Body Stick?

Throttle Body Stick is a condition that occurs when the throttle body on your engine becomes stuck closed. This can cause hesitation, loss of power, and reduced fuel efficiency. If left untreated, this issue can lead to major damage to your engine.

To avoid Throttle Body Stick, make sure that you regularly clean any build-up of gas or oil from the throttle body by using a vacuum cleaner or by flushing it with clean water. If the problem persists after following these simple steps, then you may need to take your car to a mechanic for inspection and possible repairs.


So, if you find yourself in a situation where your dirt bike throttle is stuck open or closed, remember these tips. Then, if all else fails and you can’t seem to fix the issue, take your dirt bike to a professional mechanic who will be able to help you get back on track (literally).
