How to Clean a Carburetor on a Motorcycle in 7 steps


A carburetor is a crucial component of a motorcycle's engine, responsible for mixing air and fuel to create the combustion necessary for the engine to run smoothly. Over time, carburetors can become clogged with dirt, debris, and varnish, leading to poor performance and decreased fuel efficiency. Regularly cleaning the carburetor can help maintain optimal engine performance and extend the life of your motorcycle. In this article, we will guide you through the step-by-step process of cleaning a carburetor on a motorcycle.

Materials Needed

  • Safety goggles
  • Latex gloves
  • Clean rags
  • Carburetor cleaner
  • Compressed air
  • Small wire brush
  • Small container for soaking

Step 1: Preparation

Before you begin, it is important to ensure your safety. Put on safety goggles and latex gloves to protect your eyes and skin from any harmful chemicals. Additionally, gather all the necessary materials mentioned above.

Step 2: Remove the Carburetor

Locate the carburetor on your motorcycle. It is usually positioned near the engine and connected to the air intake. Carefully remove any cables or hoses connected to the carburetor. Take note of their positions to make reassembly easier later on. Using a screwdriver or wrench, loosen and remove the bolts or clamps holding the carburetor in place.

Step 3: Disassemble the Carburetor

Once the carburetor is removed, carefully disassemble it by removing the float bowl, jets, and other small components. Place the disassembled parts in a small container filled with carburetor cleaner. Allow them to soak for the recommended time specified by the cleaner manufacturer.

Step 4: Clean the Carburetor Body

While the carburetor parts are soaking, clean the carburetor body using a carburetor cleaner and a small wire brush. Pay close attention to the small passages and orifices, ensuring they are free from any obstructions. Use compressed air to blow out any loosened debris.

Step 5: Reassemble the Carburetor

Once the parts have finished soaking, carefully remove them from the cleaner and dry them with a clean rag. Reassemble the carburetor by placing the jets, float bowl, and other components back into their respective positions. Make sure to follow the correct order and orientation as noted during disassembly.

Step 6: Reinstall the Carburetor

With the carburetor fully reassembled, carefully reinstall it onto the motorcycle. Reattach any cables or hoses that were disconnected earlier, ensuring they are securely fastened. Tighten the bolts or clamps to hold the carburetor in place.

Step 7: Test and Adjust

Start the motorcycle and let it idle for a few minutes. Observe the engine's performance, paying attention to any irregularities or issues. If necessary, make adjustments to the idle speed and air-fuel mixture screws to achieve optimal performance. Refer to your motorcycle's manual for specific instructions on adjusting the carburetor.


Cleaning a carburetor on a motorcycle is a task that requires attention to detail and proper technique. By following the steps outlined in this article, you can effectively clean your motorcycle's carburetor and maintain optimal engine performance. Regular maintenance and cleaning will not only enhance fuel efficiency but also prolong the life of your motorcycle. Remember to always prioritize safety and consult your motorcycle's manual for any specific instructions related to your carburetor.
