Default 2018 ZR 8000 catches Fire

Guess I’m one of the few who’s sled caught fire.
Was riding this past weekend across the lake and stopped for 5 minutes for my buddy to catch up. When I restarted my sled it started to smoke , so I shut it off and saw a fire starting near the exhaust. Luckily we were able to put it out. It’s at the dealer now and I hope Arctic Cat comes good for the repairs. Hopefully all that is damaged is the side panel and belly pan. Plus two sets of gloves that melted while putting the fire out.
Apparently there is a flash update recall which I never received notice of.
Anyone else have their sled catch fire?

Yes the recall is a year old. After the recall, certain conditions like lake running when you stop it will stay at high idle for a while to cool exhaust down. Shutting it off after some lake running is not great for these. I let mine idle down before turning sled off and I think if you do that you'll be fine. I wonder if they'll cover it since you didn't get recall done, good luck.

Mine idles high when I stop regardless of what kind of riding I was doing, longer if running hard. No flames yet.

If Cat doesn't cover the panels your insurance will cover the damage

The best thing for these sleds and I did it as soon as we got them both is to vent them. I know lots will say that with the new clutches and designs they aren't belt blowers and the clutches don't get real hot. I vent all my sleds just because I saw great improvements on the first ones I did and I believe part of the exhaust flames and backfiring which obviously can turn to the sled catching fire is do to too much heat on the exhaust side. It builds up after you stop so the venting almost eliminates the heat problem. The 19 RR has never flamed and very rarely backfires with the venting and the 18 High Country is better than new but still has issues but not nearly as bad. I agree slowing done just before you stop and letting them idle a bit helps.

Can you post some pictures of the venting. I was thinking the same thing but was surprised that I didn't see a lot of vent options. I also wonder how the short extension on the can and deflector contribute. Mine has the precision efi flash so no high idle but it will flame if I don't burp the throttle after a long pull.
