Bought this pipe new of a friend cheap, its the 72cc version. Would it work on my stock SA50 motor?
Im going Polini Contessa soon but IM really anxious to try it.
Im currently jetted at 78 would I have to rejet?

I bet it runs better than your stock pipe, but you wont see full potential till you bbk. you still might need to upjet. only one way to find out. don't be skerd. lol jk

Well I installed it and it sounds awesome.. Nice throaty tone. However it seemed to lost some low end torque, top speed stayed the same around 44.

The clip is lowered but haven't upjetted. Polini Contessa kit on it's way too help out.
