hey guys I need some advice on tuning my 150cc 2stroker. I'm still in the middle of the basic fabricating stage but for space reasons I need to work out what type of air filter I want now. I want to fit either a cone filter or a pancake job, but don't know how these will effect the bike. The original bike didn't have much power to begin with, and I'm hoping to modify the exhaust off something like an RD to fit the bike. (currently has a guzzi silencer, don't ask!) anyway I don't know all the science behind engines and hope some of you guys can help. Will I need to change the getting in the carb, and/or the mixture screws? is there a basic calculation used to work out cc x filter+jets+exhaust=improved performance? I don't expect to make any real power gains, its more to do with not sacrificing what little power I have to achieve the look I want, if that makes sence? cheers
