im tuning a air cooled zip and have chosen to get the following: STAGE 6 RACING 70CC PIAGGIO AC kit S-Line Evolution Crankshaft Delorto 21mm carb MHR malossi torque spring (Purple spring) Malossi Variator Chrome Pm 360 I don't know which gears are best to get for the bike, what do you guys think?
Exhaust is a shit choice, and i'm guessing you are on about a gear up, generally stage 6 is the easiest (pre-pressed)
