Bully Clutch says to break in the new clutch you are to "engage" the clutch and bring the temp up to about 250 let cool and repeat at 50 degree intervals until you reach about 400 degrees. My question is what exactly do they mean by "engage" the clutch? Should it be enough RPM 's to spin the axel and tires while setting on the stand until you reach the temp or setting on the ground with no roll?
