Went for a ride yesterday and the '11 Summit started doing some crazy stuff. The snow was deep and heavy, and whenever i hit full rpm's on a climb the front end would start to vibrate like mad. The best way to describe it is it felt like the track was chewing down on roots. If I back off on the throttle a bit it would completely stop, so I could feather the throttle to get up slopes. The exhaust note also sounds different, with a strong smell. Almost as if it's burning oil, but oil consumption is etec normal.

I had the top end and crank done last year, and have had some intermittent problems with getting full power on climbs since then. The machine pulls like a beast on flats consistently. Motor mounts are tight, clutches appear to be turning spinning smoothly.

Any ideas?

When was the last time the drive belt was changed?
