Dirt bike carburetor



When it comes to dirt bikes, the carburetor is a very important component. It helps to mix fuel and air together before the engine intakes it. This process is what helps the bike run properly.

There are a few different types of carburetor that are used on dirt bikes. Some of these include the Keihin, the TMX, and the OKO. Each one of these has its own unique benefits and drawbacks.


The Keihin carburetor is a popular choice for many dirt bike riders. It is known for its smooth performance and fuel efficiency. However, it can be a bit complicated to adjust and maintain.

The TMX is a carburetor that works well if you are looking for something that will get the job done, but won't break the bank. This design is tough and doesn't use too much fuel while still maintaining performance.


The OKO has an air flow capacity of 1.9 litres per minute and gives riders eight different settings to choose from. This makes it a great choice for those who want to have more control over their bike's performance.


No matter which type of carburetor you choose, it is important that you take the time to learn how to adjust and maintain it properly. Doing so will help ensure that your dirt bike runs smoothly and gives you the best performance possible.


How to clean a dirt bike carburetor


It is very likely that after you have cleaned the dirt bike's gas tank, you will also need to clean the carburetor. The two are directly connected when it comes to gasoline flow, so when one is dirty, the other will be as well.


There are a few basic steps that you need to take in order to clean the carburetor:


1. Disconnect the gas line from the carburetor and remove the fuel cap. This will allow any gas that is still in the system to escape so you won't be dealing with a gasoline-soaked carburetor.


2. Remove the air cleaner from the carburetor by taking out the screws that hold it in place.


3. Use a screwdriver or other pointed object to remove the float bowl from the carburetor. This is where most of the gunk will be, so take your time and get rid of as much of it as possible.


4. Take apart the float bowl and remove any gunk that may be inside. You can use carburetor spray or other chemicals to help break down the dirt in the presence of an air stream, but you must take care not to let any of these chemicals get into your engine if it is still attached to the carburetor.


5. Replace the float bowl and tighten it in place using your screwdriver.


6. Spray the air cleaner with carburetor spray to help clean out any dirt or gunk that might still be inside of it. If there is a foam element inside of the air cleaner, you should open this up and remove any dirt that might be inside of it.


7. Replace the air cleaner and plug up the open hole with a rubber stopper.


8. Reconnect the gas line to the carburetor, replace the fuel cap, start your dirt bike's engine, let it idle for two minutes, then turn it off again.


9. Remove any plugs or screws that you used to open up the air cleaner and float bowl and put them back in place.


10. Reattach the air cleaner to the carburetor.


11. Check for any leaks where the gas line is connected to the carburetor and fix them if necessary.


12. Start your dirt bike's engine again and let it idle for a few minutes.


13. Turn it off and check the air cleaner for any dirt or debris. If there is any, remove it and clean the air cleaner housing with a brush.


14. Put everything back together and you're done!


How to adjust dirt bike carburetor


Carburetors are used to meter the fuel supply in your dirt bike's engine. They are typically attached to motorcycle gas tanks and if they are not adjusted properly, this can result in less-than-desirable performance.

The carburetor for a dirt bike is fairly easy to adjust because you will usually only have two or three settings to work with. You can access your carburetor by removing the gas cap and taking off your air cleaner.


1. Start by adjusting the idle screw, which is found underneath the float bowl of the carburetor. You will need a flat-head or Phillips screwdriver to do this.


2. Make sure that your dirt bike is idling properly and then adjust the idle screw accordingly.


3. The idle speed screw should be adjusted next, using a flat-head or Phillips screwdriver again. This will help control how fast your dirt bike's engine runs. You may even need to use both eyes to get this right because it requires a great deal of visual accuracy.


4. Once you have the idle speed screw adjusted, use a flat-head or Phillips screwdriver to adjust the throttle stop screw, which is located inside your throttle slide handle. This will control how far you can open up your throttle and adjust it so that when you let go of it, it snaps back into place quickly for a smooth ride.


5. After you have adjusted the throttle stop screw, adjust your idle screws with a flat-head or Phillips screwdriver to adjust how fast your dirt bike idles. You need to do this so that when you let go of your throttle, it picks up speed slowly and evenly on its own. If it's too high or too low, it can cause problems with your dirt bike's performance.


6. That's it! You have now successfully adjusted your dirt bike's carburetor. Make sure to recheck all of your adjustments after you have ridden your dirt bike for a while so that they remain consistent.
