sounds like it unless you were running hard for a while, i would not suggest changing the ratio unless you have been in the carb recently and done some other work to the engine, i would give the carb a good cleaning first, watch out for the tamper screws in the top of the slide the are loc-tite is put on at the factory, as a last resort check the mix screw on the bottom at the motor side of the carb factory setting on these is usually 1.5-2 turns out from lightly seating bottom, the units do run lean naturally though

      1998 Big Bear running lean, real lean.
      By Bobbywolf
      I am working on a basket case for a friend.  It is a 98 Big Bear (YFM350FWB).  It came with a parts machine which is a 96, which I am coming to find out is VERY different from his machine.
       
      Anyway, first thing is first.  I checked compression, 150psi.  Valves are set correctly, and the engine is in time.  I cleaned the carb, and there was some junk in the passages.  It is a chinese carb, which I figured from the lack of markings or lettering altogether.
       
      The bike runs.  It idles ok, but breaks up badly under acceleration.  Pulling a new spark plug shows it is running lean.  White strap, with no black whatsoever.  So I have the carb adjusted with the mixture screw out way too much (about 5 turns), and the diaphragm needle lifted to the top slot.  It is still not getting enough fuel (or too much air).  It backfires through the carb, and cannot get above idle without carrying on.  The carb boot is in good shape, so it isn't pulling any air there.  I did test this as well by spraying ether around the boot when running, looking for intake leaks.
       
      Anything big I am missing here?  I am starting to believe that this chinese carb is the issue.  This quad came with the original carb, which I would like to rebuild and use, but the mixture screw is totally stuck, and stripped way down in its recess.  
       
      Thanks for any assistance.

      Running engine without rear axle 2005 500 scrambler?
      By p5200
      I'm assuming, it's alright to test the engine after adjusting valves without the rear axle installed? Can someone please verify this? I'm waiting on axle parts and wanting to get that done while waiting. Thanks! 🙂
