Clean a Motorcycle Carburetor in 4 Easy Steps

One of the main cause for all sorts of problems with your bike is a dirty motorcycle carburetor. A carburetor regulates the amount of fuel and air going into the cylinders. Cleaning a carburetor can be a tricky process but it can help you to save lot of money in the long run. The fuel will start to breakdown when the engine sits for a very long time. So it is very important to replace the fuel in the tank before you start your engine after the carburetor is cleaned.

Earlier carburetors were used on a large scale on older motor bikes and they are still used on many motorcycles today. The carburetor can be considered as the most misunderstood mechanical part on a motorcycle and if the carburetor parts are not set properly then it will be the main cause for the bike to run badly. The correct ratio of air and fuel is very important for the performance of the engine and a strange device called carburetor controls this ratio. Cleaning a carburetor is a simple task and the steps are as listed below.

1) Removing your carburetor

First of all, it is important to drain all the gas that is present inside the carburetor into the catch pan and then discard it very safely. In order to determine the best way to remove the carburetor, one can check the owner’s manual to have a better understanding.  Taking out the carburetor will be easier for some than for the others. You can also track the fuel line down to the carb and remove the hose. Loosen the screws in the clamp and slightly twist the carb to remove it. Keep a proper track on all the wires that you disconnect so that while reinstalling it will be easier.

2) Disassembly

When the carburetor is out of your engine and drained properly then you can take it apart piece by piece. Keep a proper check to where you are taking the parts out and to put them back in the right order. Check for the corroded parts that are to be replaced. One can also use a toothpick to force the dirt out. Also check your service manual as there are many bits and pieces that need to be replaced.

3) Cleaning

Before actually you take it apart, it is advised to use some degreaser and a stiff brush to clean it thoroughly from outside. Set your carburetor on a clean towel and remove the float bowl using a screwdriver. Now, clean the bowl with a rag and the carb cleaner. One can also use the air compressor to clean out the passageways. Be sure to get all of the passageways and holes. It is advised to use your safety goggles and keep other things away while shooting with this stuff as it can cause unbelievable pain if it gets in your eye.


When everything is clean it is now time to put it all together. If you have paid a proper attention during disassembly of the parts or you have kept the parts well organized then rebuilding the carb will not be a difficult task. Also make sure that when screwing in the jets don’t over do it and do not use force while putting the carbs back together. Be sure that the bowl gasket is in place and make the necessary adjustments. Use a carb synchronizer and your motorcycle manual, with the help of your patience you will be able to get it done!

After this procedure the engine will have greater power and feel more responsive. When you start your bike  your carburetor will give your engine a whole cleaner run!
