Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

I did a compression test on my 2005 Bombardier Traxter 650 CVT and it's 75 PSI. service manual only talks about leak down test. No specification for engine compression the manual. What does 75 PSI tell me? Thank in advance.
A little history of this machine. 640 miles. Picked it up about 2 years ago, not running. Probably the computer. Tested all circuits and confirm it was the computer. Long story short, I watched a Youtube video and fixed the computer. ATV now started and runs. BUT, it tops out 20 MPH. I cleaned the carb 3 times also using a Mikuni carb kit after the second time. Slide in carb is going up and down. Only adjustment for fuel is at 1.5 turns out. NGK Sparkplug had soot on main part but brown on the electrode. Champion sparkplug is brown. I check CVT clutches and they both appear to engage like they suppose to. Checked valve clearance it's 0.00, I can't get any feeler gauges in-between. I check timing chain I believe it's in the correct position and hasn't skipped. I removed muffler plug and drilled into muffler to try and make sure it wasn't plugged.

I WANTED TO UPGRADE THE CARBURATOR ON MY 1992 BIG BEAR 350, SO I ORDERED A NEW CARB FROM EBAY. ACCORDING TO THE WRITE-UP IT WAS A GOOD FIT FOR BIG BEARS FROM 1988 TO 1996. WHEN I REMOVED MY ORIGINAL CARB I NOTICED THAT IT WAS DIFFERENT FROM THE NEW CARB MY CARB HAD TWO THROTTLE CABLES THE NEW CARB ONLY HAD ONE CABLE. HOW CAN I MAKE THIS CARB WORK ON MY TWO CABLE THROTTLE? -

1996 4x4 Timberwolf rearend width. Can someone with some knowledge of these machines answer this question for me please. Are all 4x4 timberwolves this narrow in the rearend? These tires are so close the right one actually rubs the muffler. Thinking about seeing if there are any spacers out there for it. I need at least an inch more clearance.

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!!
Dave
