Provided your motorcycle is running lean, one end to excogitate is to rejet your motorcycle carburettor. Putting in larger jets Testament administer you worthier performance and a smoother drive in situations that thirst for a richer compound of fuel. Principally with Harley Davidson motorcycles, carburettor rejetting can be accomplished easily by the backyard mechanic.
Instructions
1. Positive tune your motorcycle before rejetting your carburettor. Provided it's much running very thin, you can interchange the co-pilot jet as a first off operation
2. Remove the bowl at the base of the carburetor by unscrewing the screws holding it in place. Unscrew the pilot jet inside, but be careful not to strip it. The jet size will be on top.
3. Use a screwdriver to remove the main jet from the brass jet needle holder, which is also called the emulsion tube.
4. Put in a pilot jet that is one size larger. Replacing it with a jet two sizes larger will make your mixture too rich.
Reinstall the carburetor on the motorcycle and retune it to finish the rejet procedure. The sizes are in increments of 5.
6. Put the bowl back on, and align the accelerator pump shaft and rubber boot.
7.5. Tune the slow/idle settings before replacing the main jet. Replace the main jet with one size larger.
