[cross country]

We were out in the field last night with 2 F8's breaking in our sleds. I have about 65 miles on mine now.

I was coming across the field after some WOT runs and my buddy flagged me down, there was some major flames blowing out my exhaust and when I stopped and turned it off we had to throw snow on the underside to get the flames to go out.

I know they are over fueled during the breakin period but fuel blowing out the exhaust seems a little excessive.

Anyone else have a "flaming F sled"

Nothing like that on my new sled, but I did have that happen on my F7 after a VERY long WFO run on the river. Was prolly 30 mile stretch and was WFO for 25 of them.
When I pulled into the parking lot and waited for the rest of the sleds to show up, my one buddy noticed the flames. Raw fuel in the pipe + excessive pipe heat = flame-atude

Mine did it a few times and looked at my plastic under the Snow pro sticker and its melted pretty bad. Calling Cat today

sounds like an air box mod may fix the backfire problem

I was cleaning mine up today 45°F. and noticed my plastic is melted, I think more from run-on after shutting the key off. I'm taking it into the dealer for a check-up. I'll let them adjust the oil pump and blow it up.
