Ok, I bought an RM80 with a bad top end, turns out the water pump seal failed, overheated, and cooked the piston. Bored .5mm(was already sleeved), Wiseco forged piston, new Suzuki water pump impeller, bearings and seal. From the outside the clutches looked ok, but I know coolant does naughty things in there, and now the clutch slips at anything over 1/4 throttle. Changed the oil 3 times, marginally better each time.

Is there a way to fix without ripping cover off and R&R clutches and springs?

I was planning to sell this thing, but now its turning into a $$ pit, and its waay too small for me.
