Looking to do some clutch changes. 8bu weight 17.2 inner,13.9 outer. 14.5 rollers, blue/white/blue primary spring. Stock 47 deg helix set at 6&1 with white/white spring. Ride 3000'-8000' and hitting rev limiter on take off, and pulling down a bit on longer climbs. Do you think this is enough finish?
