97 yamaha big bear starter issues

Recommended Posts

Hi. I sunk my 97 big bear in a water hole up o the seat. I drove it home after it being in a swamp. Drove it twice since and then it wouldn't start at all. I since drained the gas, oil twice, and changed the oil filter. also changed the spark plug and air filter. It fired up on two occasions only by the pullcord.(electric start has a grinding noise at first then it starts clicking noise). Ran o for about 20 minutes each, ran very high and wouldn't throttle back too much. Electric start did work before the water hole.

any help would be great to get this thing started again!

the carb probably has dirt in it, i would take off the carb, take it apart and clean it, taking out the jets and making sure everything is clear of debris ...

Thanks. I soaked it already. I will take it all apart this time. Also do you know if when I take off the spark plug wire, then pushing the start button, should I have spark in the wire? if so then There isn't any spark. Is this related to the bike not starting? thanks again

U might need to rebuild ur starter motor. They go out because the brushes where. You should be able to find a rebuild kit.

If you take the starter out and look into the motor can there should be two gray pieces of metal. Those ride on the motor shaft. They will be held to the shaft with a spring or some kind of spring steel. If those are gone you need to rebuild it.

Thanks. That would explain the gray metal filings that were all over the oil filter. Good thing i changed the oil and filter. Is getting the kit the thing to do? Is it that much for a new starter? I also noticed the ground wire that goes to the motor, is bare and smokes when i hit the electric start. Thats when the grinding noise starts. It would make sense that it sounds like the starter is trying to work. Also tried crossing the solenoid and it makes the grinding noise for a second then starts clicking. Any ideas ? Thanks

A good rule of thumbs is to never leave a wire bare a specially in water.

A new starter is normally pretty price for a little motor. Normally a rebuild is way cheaper if you can find one. And the grinding probally means you need new brushes.

thanks. I rebuilt the starter. cleaned the carb again. put it all back together. Now pushing the start button, it now makes a humming noise. trying to cross the solenoid just clicks. checked the voltage on my battery to the solenoid, and to my starter all is fine there. any suggestions?

Does it still start with the pull? That doesnt seam right. However how old is your battery. The voltage doesnt always matter. My battery would charge but i couldnt get it to start the solenoid would just click. I got a new battery and it fired right up. If your battery is old you might need a new one. I know that is pretty obvious but there are some simple things you dont think of

Hey everyone. so again no luck today with all the tips. took things apart and cleaned them, battery was charged up to the best it could be. 12.8 volts from 12.3 and 550cca up to 660cca. I think that is the cranking amps(not my area). local dealer told me the battery needs more than what mine is putting out to have the starter relay work. So its still just making a humming noise or buzzing sound from the starter relay when I push start button. Also will not turn over from the pull start. Any Ideas?

Now the pull start wont work? That throws a curve ball. It may be partly electrical but not fully. Last time you shut if off did it die or did you personal shut it off

I think your right. Found a ground wire( i think) that had the casing melted off and the bare wire was showing. Last time i hit the start button it heated up and seperated. I since spliced together and tried the start. Again just the same buzzing sound.

      Hello everyone! I recently purchased this quad for a mere 300.00 and it is pretty clean for the year. I bought it from a guy who bought it in a storage unit. He didn’t know anything about it. I got it home and noticed it did not have an ignition coil for the spark plug. I bought the ignition coil, a new battery, new CDI box, new starter relay, new safety neutral relay, new carb and so on... I got it to turn over, but when I pull the plug and check for spark I have nothing.. it has a non factory starter button that works when I push it and turns the engine over no matter if the key or stop switch is on or off..not sure what that’s all about, but it does turn over..just no spark at the plug. Any help would be greatly appreciated! Thanks!

      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!

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      I have a Yamaha Big Bear 350 and the reverse doesn’t work, it shifts from low to high easily but it won’t go back to reverse. I’m new to this stuff, so I’ll take any help. Any ideas?

      Hello all, 
      i just rebuilt the top end of a 99 Bear Tracker 250 and it can’t get it to hit off of gasoline or starter fluid. Occasionally it will backfire. Right now I’m just trying to get it to fire off without the carburetor like I’ve done a thousand times before with other engines. Usually there is no response, but occasionally I get a backfire through the intake. ISeems like it’s out of time, but I don’t see how that could be possible. 
      Here’s what I know:
      1. compression 120psi
      2. all timing marks are lined up after numerous revolutions. 
      3. Strong spark. 
      4. Valves adjusted correctly. 
      Thanks in advance.
