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!!

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!

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! 🙂

I got my no spark issue sorted out, got it running on the old aftermarket carb, but it didn't want to take throttle even after cleaned it, didnt really want to waste time on it, so I order a new one which is on its way, so not much to post here, but I wanted to start a new thread. I am stating to clean up the plastics thought I might as well do that while they are off, they were a mess tree sap, bird dropping, mold and what ever. Washed them good and got all off so I could see the oxidation , decided to wetsand with 600 grit waterproof sandpaper, and used Armour All instead of water. I figured it could put some of the moisture back in that was lost from sun exposure.
Working fairly well I will keep going finer on the grit and see if it will polish
