I just bought a Yamaha Big Bear 350 from 1992. The previous owner has run it on regular engine oil and I have problems with the clutch slipping. I think that's the reason.
So what should I do?
- Just change oil and it will be OK?
- Clean engine/clutch + new oil?
- Or do I need a new clutch?
It is guessing the centrifugal clutch that slips. It has two clutches , it also has a "regular" clutch .
Anyone who has any experience of using wrong type of oil?
