Im currently riding a 08 Tomos LX, with a 22 tooth rear sprocket, up-jetted to a 58 jet, added a uni air filter and of coarse the biturbo exhaust. Is there anyway to tune the bottom end of the pipe? Im topping out at about 40. I've heard about the clipping the clutch springs, is there any other method?
Or am i better off down-jetting and just putting the stock pipe back on?
