I have just moved my sled out to Jackson, WY. I am having problems with clutching. I have a PSI engine 600 bottom with 800 jugs with PSI pipes the engine is strong I had it in MI with stock 800 clutching for under 3000 feet. But here the clutch engauges at 4000 and the engine will not rev over 7000 I have reduced the weight on the drive clutch (which raised engaugement rpm) I have already changed jet size. Do I need to reduce the weight and spring on the drive clutch? Do I need to mess with the driven clutch? Any suggestions
