John, what kind of clutch stall speeds are you guys running with the SR-Y? Good to hear you’re getting that much time out of the motors. Mine should be fresh for the next race. Are you doing rings or pistons in-between rebuilds?

No rings and pistons between rebuilds. I use Burris Castor and Burris Blend. 4oz of each per gallon. I run around 8,900, but I’m still using a Horstman wet clutch.
