my 99 mxz 600 is revving to about 8700 rpm with the epi clutch kit at #3 clicker postion. Peak power is 8000 for this sled. I changed the clicker position to #1 and it still revs about 8100-8200. When i hold it full throttle from a dead stop the rpms shoot to about 8200 then come back down to 8100. After awhile they climb back up to 8200. The gearing is stock and I have an 11/4 track on it.
