1993 Yamaha Big Bear - Starts/Runs w/Choke

Recommended Posts

I recently purchased a 1993 Yamaha Big Bear 350 for $300 from a guy at work who could not get it running, getting rid of old fuel and changing the plug it fired up, it has a new carb rebuild that was done before i bought it, problem i have is that it only starts and runs on half choke, even in the -15 celcius canadian weather today. im not sure where to start on this, any help would be great, thanks.

just let it soak 24 hours. then after in another bucket with warm clean water, swirl it around and then spray it with carb clean. the pine sol is ok with all the rubber fittings too. i cleaned my carb to what i thought was perfect before, but never was right. after the pine sol treatment, it works great !!

yeah, sounds like a full carb clean is in order - too many people think yanking it apart and spraying it down is the same as a rebuild. Make sure the pilot jet is clear - if you don't have a jet cleaner set (K&L makes a nice one) a single wire from a wire brush is typically small enough to poke through.

      My father-in-law gave my boy a 1999 350 Big Bear. It's been sitting in a barn for a bunch of years. It runs great! My boy has been riding a couple weeks now and it has developed a squeal coming from the front end when you get off the gas at speed. No noise during acceleration. At first I thought brakes. I took it for a ride and I don't think it is the brakes. I feel it is the front prop shaft U-joints, front differential or one/both axles. I pulled the fill plug on the differential and I can't find anywhere how much gear oil should be in there. My gut says up to the fill opening. It doesn't have a manual. It's wet in there, just don't see any gear oil.

      #1 Should I fill the differential with gear oil up to the fill opening?

      #2 How do I check or know if the u-joints are bad? That looks like a "Big Bear" of a job if they don't need to be replaced.

      #3 What else could it be? I don't think it is the front bearings. I jacked the front wheels off ground and no play in the right wheel. Very little play in the left wheel, looks like the lower control bushing is where that play is coming from. The rubber CV boots look original but all still intact. Wheels spin easily without any noise.

      Thanks for any help!

      Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎

      Looking for anybody who can point me towards a free service manual for 1998 Big Bear 350. I found the sticky thread but all the links, from 2012, no longer work. If anybody has one please let me know. Thanks

      My ATV started making a rubbing and clunking noise. I took the skid plates off and found that the front u-joint on the shaft that connects the front axle to the transfer case is toast. My manual does not reference this repair. Looking for instructions.

      Somehow I lost all of my spark on my 350Big Bear, its a 1990. It ran well for maybe 3 days! Thought it was the carb. Cleaned it 4 times. It was losing power at midrange. Got worse and worse. Finally nothing!
      Are these good coils? I was thinking I could swap?
