Nothing seems to be binding in the drivetrain, and I have replaced all of the ball bearings with Avids. Any suggestions?
Is the timing at your motor at the last mark to the +. I was running up there yesterday and geared at a 3.4 with max timing for the first round, then went down to a 3,32 for teh second round. i was considering going lower for the mains that didnt happen. I never got above 145 on the motor temp.
