Your best bet would be to look at a repair manual, or contact a Yamaha dealer for the info. Stock pilot is 42.5 and stock main is 95. 1 1/2 to 2 turns out on the pilot screw is a good place to start. The middle slot is a good place to start with the needle clip postition. See how it runs and make one adjustment at a time to get it dialed in. Pay attention to what your plug looks like while you are getting it tuned.

      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!!

      1989 Yamaha Moto 4 sputtering after new carb
      By jashadams
      Hey all back again with my 1989 moto 4 250.
      After putting a new carb on it it's really sputtery, it has new gas and I'm wondering what to tune on the carb to make it idle better. I've attached a video to describe the issue more. The bike is still work in progress but I think the video gets the point across. Thanks!

      Need opinions on whether I should pull carb on 2005 Scrambler
      By p5200
      Hello folks, my machine wound up with I think water in the tank etc. It runs but speeds up and slows back down randomly. When not running I don't see gas dripping  from the drain nipple on bottom of float bowl and drain screw is closed tight. With normal idle speed I see no leaking. When the idle speed increases quite a bit on it's own, gas appears to start slowly dripping from float bowl drain nipple? I'm wondering if the carb is flooding and the gas is actually coming from higher up and just appears, to be coming out of nipple but, is actually running down the sides of the nipple? I put a kit in the factory Mikuni carb last year after sitting for a while and I think the gas in the jug I used had drawn moisture. I plan to pull the carb tomorrow and clean everything out. I was just curious if anyone else thinks it's probably something in the carb and is, acutally a flooding problem? Thanks Folks! 🙂

      2006 700 carb just died(electrical)
      By STLJ
      Hope everyone is having a great weekend,
      While riding my quad just quit, I mean dead. No life on the dash, no crank and obesity no start. 
      Had a quick look under the plastic, batt reading 12.7v power at the key switch.
      Changed the power pack, still no luck.
      Anyone else have similar problems?
      I don't see a fuse box/panel, is there fusible links in the system? If so where di I start looking?
