Start VERY FAT, and then go leaner - to ensure no detonation

Note: Please confirm the parts will be fit on your scooter/motorcycle before you place the order.

Carburetor jetting: You must set the carburetor jetting correctly by experiment. Put the main jet in, and run it full throttle long enough to get the plug colored. The best reading on a 4-stroke is a light tan, with perhaps some darkness around the edges. Some factory setting are so lean that they are bright white.
