yamaha big bear 350cc what year do i have??

[mike91]

I’m just wondering what year bike i got? it seems the vin has been rubbed off i got it from a auction here in Australia engine starts but seems has a dirty carb wont idle well

and also has a problem I put it in gear and makes a grinding noise but does not move it the neutral light goes out but then when I change gear it grinds more in the higher gears as well I’m guessing the differential is stuffed so wanting to buy new part for it will start the pull down next week

this is the first bike I have worked on used to dealing with cars

Looking at the parts diagrams it is a 1996-99 Kodiak 400. I'm going by the front fender and guard. I don't know why it would have the Big Bear decals on it though.

This appears to be about a 2000 big bear. The big bear and kodiac are very similar. I looked up some pics of big bear atv and seen one looks like it but different color  and it was 2000 model.

Oh just got through rebuilding a Differential. It cost about 350$ in parts. The problem was the ring gear/axel was stripped out. Had to have all new bearings, seals, axle, and ring gear in differential. Since you have to tear it all down you might as wheel replace the wheel bearings. If you do tear into it make sure you take all spacers that space ring gear , pinion gear and mark the from witch side they came off. It make a big difference when you go back together these have to be back where they came from.

If the OP is still around, maybe look for an engine serial.
