well, i don't want to do anything w/ piston. but i'll try the smaller jet. and i'll try the modification on the airbox. what about the airbox cover that's just round and has no "box". would that be even better?
i don't want to drill anything. i'd like a bit more speed. but gaining another 2mph at the risk of wrecking a cylinder or something just isn't worth it to me.
i know the sprocket will give me more top end. but i don't want to loose to much acceleration. so i'm looking for easy mods that can let me keep some bottom end.
thanks for the suggestions.
