How To Rebuild A Motorcycle Carburetor – If you’ve bought an old motorcycle for a DIY rebuild project or want to revive a classic V-twin motorcycle that’s been sitting in your garage for years, carburetors are all varnished and need a thorough cleaning. Learning how to rebuild carbs on a motorcycle can take some learning, but it saves time and is cheaper than replacing them with new ones.
By following a few basic steps, dismantling and rebuilding a motorcycle carburetor is relatively simple, and it’s more rewarding when the bike runs smoothly afterward. Before you begin, take several precautions: Wear safety glasses and safety gloves and work in a well-lit and clean area. Here’s what you need to do to rebuild carbs on a motorcycle:
How To Rebuild A Motorcycle Carburetor
Get your motorcycle service manual and read through it to understand the exact steps you need to take to remove and disassemble the carbs from your motorcycle. To remove the carbs, disconnect the attached lines, loosen the screws used to tighten the manifold clamps, remove the air box and push out the carburetor rack.

The most important thing when learning how to rebuild carbs on a motorcycle is to take things slow and keep things systematic. Also, make sure you have a dedicated work space before you start disconnecting the carburetors from their racks and working on each one individually.
With your rack carburetors off the bike, begin disconnecting them by simply unscrewing them from the rigid mounting plate. In most cases you will find 2 or 4 screws holding each carburetor in place. Before you can get to each carb, you may need to remove the throttle rod and throttle shaft. Make sure you have separate containers for each carbohydrate in your workspace.
This is important because you want to keep all of the internal components of each carb with the body you disassembled. Remove any rubber parts and set them aside before using any type of cleaner. Learning how to rebuild carbs on a motorcycle is an important step, especially if your throttle discs work with a rubber diaphragm.
Be careful when removing the throttle slide, as the rubber diaphragm can stick if the bike has not been used for a long time. If the chip is stuck, you can soak it with penetrating oil or use a heat gun to apply some heat. This makes the throttle slide plates and drive trays east to rotate. Access and removal of most jets is possible from the bottom of the carburetors.

Remove any plastic or rubber carb floats and O-rings before using carb cleaner. When it comes to removing the air and pilot screws, turn them individually until they stop and count the number of turns. When you reassemble the carburetors, set the same number of counts for proper installation of the screws.
Remove the carb jets being careful not to dislodge them or break any legs or struts with the carb body. Use carb cleaner to gently loosen any varnish fusing components. Check to see if the jets on your carburetors can be removed or not, just to be sure. Your service manual should guide you on how to rebuild carbs on a motorcycle.
After removing all the necessary components, you can dip the carbs in a recommended carb cleaner to remove the varnish. After a short soak, remove the carburetors and wipe off any excess carb cleaner, then spray each pass with the recommended spray carb cleaner. For shorter paths, use thinner wire. Again, safety is paramount when handling carbohydrate chemicals.
If your carburetors have been cleaned, it’s time to rebuild them. During the disassembly and cleaning process, you should have already noted any worn or damaged components so that you can get the right replacements. To make this process easier, it is advisable to purchase aftermarket carburetor rebuild kits.
