I recently bought a 97 Yamaha Mountain Max 700 triple. Been having issues with the idling and it backfiring. The only time it sounds like the sled is idling the way it should is when the choke is on, but when I shut the choke off and just let it idle on its own it sounds like its only running on 2 cylinders and sounds like crap and when I go to give it throttle it would backfire. Keep in mind there is no snow yet and haven't even rode it yet, just started it and noticed it isn't running the way it should.
I have read a lot of threads on here regarding same issues so I did take the carbs off and cleaned them(not guaranteeing it was a thorough carb cleaning though). also checked plug wires on coil pack end and at the spark plug cap. Tried checking spark plug caps with ohm meter and not sure what I'm doing cause nothing reads 5k ohms so probly doing that wrong. Also unplugged Tors system and hooked wires back into themselves and no change.
Now since I cleaned carbs and put back on when I start the snowmobile whether I have to choke on or not it does not idle well at all. Just sounds like it's running on 2 cylinders all the time and have to keep flipping the choke on and off to even keep it running. Any help or ideas?
