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?

      Issue with 89 Yamaha moto 4 250cc
      By Need-help-with-quads
      So I have an 89 Yamaha moto 4 250cc and when I ride it, itll get hot after like 10-15 mins and then will just die and turn off.
      It's has new carb rebuild, new air filter, new battery, new spark plug so I don't think it's a crack in the spark plug
      Can anyone help me?

      86ccord's Big Bear 250 Build!
      By 86ccord
      Starting this build thread to keep up with everything on my build and hope to motivate someone!
       
      I picked up this 2008 Yamaha Big Bear 250 2 weeks ago. A guy that I hunt with parked it at the hunt club for a year or so before I asked him if he wanted to sell. He said " fill my feeder and throw some batteries in my cameras, and you can have it". Sounds like a deal to me! 
      I have attached some pictures of how it sat under a tarp in the woods and when I got it home and cleaned up a little.

      1988 LT80 Crankcase Full of Oil
      By JohnnyB
      Greetings, 
      Have a 88 LT80 that been sitting for a couple years. Bought a new piston, cylinder and head. Installed these, rolled it over and it quickly locks up.  Took carb apart. It was full of what appears to be 2 cycle oil. Cleaned it, but keeps locking up and 2 cycle oil continues to seap from exhaust port.  When i installed new cylinder, I noticed crankcase was full of oil.  I'm now wondering if that oil is what's getting sucked up into cylinder.  Should there be no oil in crankcase?  If that the case, how is crank and rod lubricated?  Sorry, never worked on a 2 stroke. Thanks!
