Im running an 08 Nytro with a 162, Undertunnel exhaust. About it for performance upgrades. Anyways im running stock clutching except for a GWG in the primary and an Arctic Cat yellow (10*) in the secondary. I need like 500 more rpms. My clutches are both very cool. What should be done to get a few more rpms? There currently are no rivets in my weights. 8000ft +. Also im loosing about 600-800 RPMS from trail to steep and deep this about what everyone else is seeing?
