Hello All, I have a 1999 Yamaha Big Bear 350 4x4 trying to get fixed up so my grandson can go out in the woods with me. We have owned it over 10 years. It got harder to start, until it finally would not. Replaced the carb. Right afterwards, it started and ran nicely, but after turning it off, would not restart. Tonight I used starting fluid and ran, then died. Adjusted the idle up a little, used more starting fluid and ran great. It idled about 15 minutes. Turned it off, and restarted. Ran it around the yard about 5 minutes. Turned it off, and would not restart. Any ide

Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all. Nick

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 ha

I picked up a 1997 Yamaha Big Bear 350 2X4 a week or so back in non running condition, apparently they said it needed a new carburetor or a battery, I cleaned the carburetor thoroughly and got it running on idle and without choke now and it shifts into all the gears even into reverse. Aside from making me bounce a little when trying to start out with a bit of throttle the shock suffice to say needs work. Anyways I made a video of it running and would like your opinions on it, as to how it sounds while running. It seems like it has a little whine I'm not sure why that is maybe someone can tell

1987 YFM350FWTB 350 4x4 Big Bear when going uphill will sometimes act like the clutch realeases then re-engauge all at once. Seems to maybe be little more often if the engine is at about 1/2 throttle instead of at lower rpms. I have the Factory Service manual and checked the external clutch adjustment screw as ok and the H/L/reverse shifter lever linkage as adjusted correctly. It appears to be maybe a internal (inside the case) clutch issue or ?? This is the type Big Bear that has the manual shift lever on the left front fender and has the manual foot shifter lever with 5 speeds

My old Big Bear nearly left me stranded but I managed to limp back to my garage just before it died. Now No Spark. I’ve changed the obvious, inexpensive and easy parts- spark plug & coil without any luck. Ive stripped it down and traced all of the related wiring, checking as many connections as I can but no luck again. Next I pulled the cover and accessed the stator housing to inspect and do some resistance testing to ID a possible short. Here are my readings: Source coil- 325 ohms Pickup coil- 225 Can anyone tell me if these are good numbers, and if good,

I have a 1988 Big Bear 350 4x4. I had to take apart my front brake pistons and thoroughly clean them. The internal gaskets appear new from when I had bike shop I thought do a brake repair. Seems like they just replaced gaskets and didn't bother cleaning or clearing any of the trash from system. I put everything back together and try bleeding system and pumping up brakes. The front piston on both sides will just barely build up and it does hold and when I bleed them I get a solid stream of fluid so don't believe there is any blockage. Also to note the bleed valve is after the rear piston on eac
