Thanks, that would make it three then.....Brief history, bought a DT80MX which was nice but seemed to be put together by Stevie Wonder.....Had a bad slipping clutch and on inspection had a DT 50MX Clutch basket assembly fitted which might have explained the problem.....Managed to obtain a rare now 80 mx completed clutch assy, fitted it but still seems to slip a bit......done all the adjusting I can but still slips....new friction plates etc etc. Just got some heavy duty springs which i hope will solve it. The mad thing is if you go on the Yamaha data system for parts it shows 4 friction plates which contradicts the Micro Fich which shows 3........!!!!!! Hence this post.
