2003 Yamaha Big Bear 400 idle problem

Recommended Posts

I have a 2003 Big Bear 400. It is cutting out when idling. I cleaned the carburetor, changed spark plug, and reset the valves. It runs fine at higher RPMs but when it is idling it cuts out and dies. I adjusted idle speed but it only revs up to higher rpms than what it shoud at idle.

Water in the fuel or some bad gas? Did you run some Seafoam and or Stabil through it to see it that settles it down?

      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!

      doesn't idle at times but sometimes when it does as soon as I touch the throttle it just shuts off, what could possibly be the problem? I thank you very much for any help, 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!

      I have two 2003 Suzuki Ozark 250s, both 2-wheel drive.  Last time we rode them about a year ago, the red one was not running well, didn't want to idle, backfired a lot.  The green one ran fine. 
      Fast forward...I ordered a carb kit for both of them, thinking the red one has some trash in a jet.  Both of these ATVs have had little use and I've always ran the gas out after use (put an inline cutoff valve in gas line).  I pull started the red one to verify it was still running bad.  It will start and idle, but as soon as you give it any throttle, it dies instantly.  Give it a little choke, dies instantly.  Took the carb apart and it was spotless.  Went ahead and cleaned all the holes with carb cleaner and blew everything out with compressed air.  All new jets, main jet holder, and needles.  Put it back on and nothing changed.  Starts, idles (not for a long time), but dies as soon as you give it gas.  Same happens when you put the choke on.  It does the same thing when I try to run it turned to prime on the petcock as it does in the on position.
      Not an air filter issue.  It is clean and it does the same exact thing with no filter on it.
      Thought maybe there was a float issue or maybe a damaged diaphragm, so I took the carb off the green Ozark and put it on red.  Started up and initially ran normal and revved for about 10 seconds and then started doing the same exact thing.  Starts, idles (not for a long time), but dies as soon as you give it gas.  Same happens when you put the choke on. 
      So...not the carb
      Thought maybe vacuum petcock was bad, but there's no gas in the vacuum line going from petcock to carb and gas flows freely when on prime.  I even plugged the vacuum line at both the petcock and carb end and tried to run it with valve set to prime.  Gas flows freely, but does exactly the same thing.  I unscrewed the screw at the bottom of the bowl and gas flows thru carb and out bowl drain line when petcock is set to prime.
      So, I'm assuming petcock is good?
      Checked spark plug and it wasn't fouled.  Reset gap, didn't help.  Will swap plugs between Ozarks tomorrow but I don't think that is it.
      Anyway, that he history and now you're all caught up.  Scratching my head.  Valves? These were bought at same time and have had little use.  Suggestions?
      Thanks!

      I was riding my 400ex one day and when i shut it off to put it in the garage i tried to start it put again to drive it into the garge and it wouldnt start.I put a compression tester on it and its like 30 psi with out throttle and 0 psi WITH THROTTLE.
      when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out 
       
      Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
      When i try to pull start (push start/roll start) it made a not normal sound  and wouldnt stay running.
      If my bottom end is blow why would it still turn over fine,
      Are my valves siezed or not working properly 
      or is my timing off causeing valves to not open in correct order with fire 
      PLEASE HELP all help is appreciated
