Good job try heavier weights other a lighter spring on your primary clutch

Are you over reving? If not you will need a primary spring with a lower starting rate and the same finish rate. If you just add weight to your clutches you will shift to high and lack performance and make lots of belt heat.
There was a thread on here last year that a guy put a apex motor in a 1000rzr search for that and he might be able to help you out.
