looking for more power from 50

[ace75]

Hey guys, we have a 2010 50 with drr aluminum cylinder, 21 pwk carb 108 main and pod filter. Stock gearing and no clue if clutching is stock or not. The guy i purchased from did mx and we are doing mostly enduros. Any advice on clutching, gearing etc. What should I be looking for with clutching to determine if stock or not. It has a one piece pipe on it that I think is a stock 70 pipe ( thats what he told me). I purchased a Hetrick built 90cc engine from a buddy this year for the future and it came with a new Gen 3 pipe, should I try this pipe on the 50? Any pointers would be great.

An exhaust change could be huge, get a mach-1 50cc pipe no other pipe is close, then do your clutch adjustments to match pipe. We gained 10 mph just changing the pipe and clutching.
