Big Bear 350 leaking oil

Recommended Posts

Hello, 

I have a 1998 (i think) Big Bear 350 4x4 that is leaking oil out of where the front drive shaft goes into the engine. Below is a vid. I have the c clips off the U joint but before I knock it out I'd like some feedback. Any idea what seal this is? Can it be fixed with simple tools? How to repair? ECT... Any advice would be greatly appreciated.

      Oil is getting in the air box from crankcase vent tube, I put the two hoses that go to the air box together then something started to smoke on the front of the engine. There is a filter? In the line I blew that out.

      I just saw a video on TikTok where some guy took the rear end off an ATV and bolted on a roto tiller in place of rear wheels. I wish i saved that video to post here....good thing it was 4 wheel drive...lol but, it seemed to work.
      I'm not sure how he made it bolt on to the drive....

      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.

      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!
