My sled along with my buddies sled are only maxing out around the 7800 RPM range on clicker 6. Both are stock sleds with just a can added, both are around the 2500 km mark with the new top end rebuild and new reeds. Sled's run great, they just don't hold the nice high numbers they used to on clicker 4. About a month ago i was always between clicker 3 and 4 and my sled would hold 8100-8300 and that is a huge difference. when the sled holds those numbers, it screams and climbs amazingly well. now it feels like 3/4 throttle, it's really frustrating. I don't know much about clutches and how to tune them, but has anyone else run into this and what have you done?
