Need help with a tuning kit, how do you tune your scooter, which kit should I choose, and all general tuning and modifcations questions are for in here.
Hey guys, Race rapido 225, open carb, what is the ring gap tolerance and what sort of mileage have people been getting out of a set?, done over 3k on mine. Any thoughts? Cheers, Bob
I'd say maximum gap for a good running engine,something around 0.55-0.6mm ( 0.025’’=0.6mm),I have ran Rapido engines with 0.8mm gap but they were lacking power. I've only used 1mm Wiseco rings. 3K plus miles with open carb,doesn't sound bad.
Thanks lads, just starting to notice a little loss of power on hills, still drives fine tbh, just wondering if they get to a point when they weaken after a particular mileage.
Not the easiest thing to say, some factors that can affect piston ring life, use of filter,chamfered ports,size of the ports,running in period,riding techniques.
