Sputtering and running like a dog - please advise

[SLEDSTART]

I would do a few things......gas line antifreeze is first. Just to eliminate the water in the gas thing. I have had it happen 3 or 4 times and it sounds like the same symptoms.

Second, check your airbox for snow ingestion. If the sled has been outside in the snow for a while the 2 vents at the front of the hood let snow fall down into the snorkel and it'll run like crap. Had it happen on a day with a deep snow fall. Once the snow is in there it's tough to get it out.

I doubt it's your donuts. I JUST changed mine at 10000 miles.

TORS will show a code so I doubt thats it.

I would not ignore the doughnuts. Mine were completely gone after 6000 miles. It also will damage the flanges on the exhaust. Replace them as regular maintenance. My sled never backfired until it was too late. By that time it was trashed in there.

One way to eliminate the TORS from the equation,
open hood find the black wire together with a black
with white stripe wire at the carb rack, unplug them
and then plug each harness into itself and reride.
that will unplug the TORS. if it still misses your
problem is elswhere.
