Does anyone know what rpms this thing should be running at? I want to figure out my clutching after the motor is rebuilt. Thanks

I have searched the forums and found old replies about this ranging from 7500 rpm's to 9500 rpm's. I need something a little bit closer than that. Comet says to use a White spring (82lbs engagement to 160 lbs at shift) (rate=65) and 46.5 grams tip heavy weights. Kinda seems like that wouldn't at up to many rpm's at the top end. Any thoughts?
