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? -

Hello I’m new here and was wondering is anyone knew of good replacement part numbers for front struts and rear shocks for this atv? I think I’ve found a new rear shock, that looks like the original but there is no dimensions or anything and was wondering if there are any afterMarket new front struts available. I know it’s a long shot but any help would be appreciated.

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.
