Anyone had this issue? Was making a loop in Canada, and it went right in the trail.. trail thankfully I was right by the road.. 850$ tow bill just to get back to the truck.. Center believe this happened on a like new sled.. My first Arctic Cat.. Should I just put stock piston in? Or go with something stronger? Don't want to bore it out. Just keep it stock

Stock piston is fine.
Replace cylinder if damaged.
Did you melt it down or smash a piston?
Smashed, poor warm up OR power valve may have made contact.

Definitely wasn't warm up because it was about 90 miles into that day... Unbelievable.. I thought it ran out of gas, but it was running on 1 cylinder

I mean poor warm up practices taking out a piston.
Do you know if it burnt down or broke a piston?
Exhaust valve cables fallen off will see it drop a cylinder as well.

Also noticed a couple stops before it happened, the sled would have a slight backfire /pop when I shut it off..

I don't know,I would start it in the morning and let it idle for 5 minutes or do before I would take off. But I would put a few miles on it before I would run it harder.. I just had the compression checked and it was only around 30..ill have a cat dealer look at it when I get home

backfires i believe are pretty common, we did a rally last weekend when it was like -2 C and every sled in our group was popping when we shut them off

When it's warmer and your'er riding hard, if you don't let the engine idle down before shutting it off, unspent gasses in the pipe go boom.
