Hi.

The air cleaner case has 2 ducts coming from or into it one goes to the carb.

The other duct on mine is not connected to anything other than where it comes out of the case. It has an open end about 1 1/2" dia ending under the gas tank with a crankcase breather connected to it.

Where should it connect to ??? (cannot see it in the service or owners manual) nor can I see any suitable connection point.

      What is the best way to remove the carb on a 2000 quadmaster 500? Does the gas tank need to come off first?

      By dkgg5755
      This thing came with a cheap aftermarket carb on it the problem I'm having is it won't start with choke installed into carburetor it will start and get run without it installed then bogs out after about 2 min run time I've checked timing , compression, checked valves for proper clearance , also did a smoke test for air leaks found none.

      2007 Yamaha Grizzly 350 carb mixture screw
      By Louznmemind
      (Question is at the end if you want to skip my blabbering) I got this unbelievably well taken care of Grizzly 350 in for a carb clean, it belongs to an elderly couple that bought it brand new in '07. Apparently whoever has been doing their oil changes for them never checked the air filter..
      Obviously it got debris in the carb, it would still run but only idle with slight choke. I've taken it apart and cleaned it, have new o rings, gaskets, etc. As far as the mixture screw is concerned, I'm assuming I obviously need to remove the plug. I'm mainly a lawn equipment guy, I've worked on slide carbs in the past but never an unmolested one with the plug still intact. I hate to mess with it as the carb had very little debris but I'm sure the o ring needs to be replaced at minimum. Finally, the question: what's the best way of removing the plug? I DO NOT want to mess up this carb..

      Help with 1987 Yamaha Big Bear YFM350FWT Carb
      By ResQ91
      Hi Guys!

      New member and could really use your advice. I would have to believe this has been an issue for others but a search here came up with nothing......? (Probably me not doing search correctly)
       
      I have an 87 Big Bear 350 YFM350FWT
      The OEM Mikuni BTM carb is shot and would rather replace than rebuild.
      It is no longer made and I have had good luck with NICHE carbs so I ordered a #K-CRB-0006 This was what they said was replacement when ordered. This Carb only uses 1 Throttle cable. The Slide is linked so it uses one. (OEM had 2nd cable coming through top to move slide)
       
      Problem is when I ordered a replacement Cable from NICHE (#C-CBL-0061) the Cable wire is a little short, not allowing Throttle to return all the way down to Idle position. I called NICHE and they are at a loss. Haven't gotten back to me after 2+ weeks.
       
      What would you recommend other than a carb rebuild?
      Can I just use 1 of the OEM cables (It is the right length) and snip/disconnect the other that went to top of Carb for Slide?
      Or ??
       
      Thanks in advance for any advice you have!!

      My carb is kaput.  Cannot be rebuilt.  Anyone know of an aftermarket carb that will work or a source for used carbs for this model and year?  Any info appreciated.
      Thanks ahead of time.
