When you buy a new carburetor or upgrade your engine, the jetting will in most cases not fit the actual set-up of your bike, and you won't get the maximum performance out of your engine.

This Main Jet Set Polini with PWK / Polini CP type jets will help you with finding the best mixture for your engine and set-up.
