A common problem that plagues carbureted motorcycles is the tendency to develop a clog during extended periods of inactivity. Clogs are caused by the slow degradation of fuel, which turns into a greenish sludge that clogs the carburetor's fuel jets and passageways. This effectively strangles the carburetor and prevents the motorcycle from being fueled properly. Cleaning a clogged carburetor can be a tedious job, especially when it comes to clearing the tiny jets. Fortunately, the job can be made easier with the right tools.
1
Pour an equal amount of water and cleaning solvent into a metal pot or container. Place the container over a hot plate or similar heat source and bring the solution almost to a boil.
2
Disassemble the carburetor and carefully remove the clogged jet from the carburetor.
3
Remove any rubber O-rings that may be attached to the jet and submerge the jet into the warmed carburetor cleaning solution. Allow the jet to soak for 10 minutes.
4
Remove the jet from the cleaning solution and rinse it thoroughly with clean water. Allow the jet to dry naturally.
5
Check that the jet has been cleared by blasting compressed air through the jet. If the jet is still clogged, pass a small, stiff wire through the jet and soak the jet for another 10 minutes.
6
Reinstall the jet into the carburetor and repeat as necessary.
