Post New pipe. No more bottom end power.
So I just installed the Gianelli reverse exhaust pipe and the 5g rollers that came with it (had 7g previously that came with my NCY CVT kit) and the increased top end power is great but the bottom lagging tough. Scoot used to take off like a banchee before the pipe. Do exhausts really affect the low end that much or am I missing something?

BBK (came jetted for this from original owner), NCY transmission kit (5g rollers and 105mm clutch), Gianelli Reverse pipe

Couch to springs need to be stiffer you changed the power band with the pipe so it doesn’t make power till higher rpms

I am experiencing the same thing, granted I went from a stock pipe to a C16. You are saying a Contra spring would help? Or do I need some different clutch springs?
