My XM misfires, when at full throttle while tipped over on its right side in deep snow. (Basically doing a hard right hand turn out of a descent). It does it every time when in very deep snow turning right, leading me to believe that there is a problem, not a random thing. Anyone heard of other sleds with this problem? The engine sounds like its missing, no spark or fuel on one cylinder, and loses power for a few seconds until I straighten the sled up.
I thought that it could be the rev limiter, so I clickered down, no change. I thought my air box was getting plugged, but nope, still does it with clean screens. The only other likely suspect is that the exhaust is getting plugged up, but another XM doing the same maneuvers wasn't having any trouble. It could be a electrical thing, loose wire that loses contact, or a fuel thing, fuel pump grabs air and the injectors miss, but none of those things would be affected by deep snow, which is the only place it does it.
Anyone else having the same problem or have any ideas? Its not something I can reproduce for the warranty guys in Calgary to fix... it just partially ruins a deep powder day in the mtns.
