Ok crazy Question,99 grizzly 600.I should know this answer.. we were riding to in 12 inches of snow on the trails..everything froze up...snow packed everywhere..I would be running the road 40-45 mph for a miles or so to get to the next trail and it would stop running,shut off..I did drain the bowl and it still stalled.happen a few times in between trails..I let it sit a few minutes and would run great for a few more miles..it never stalled on the trails though.at the end of the trip I noticed the hose going to the gas cap was plugged(I couldn't suck or blow though it)..vapor locked????? I tried to plug it again when I got home and revved it up in the garage but,it still stayed running never stalled..oh it got worse .I hit a rock and bent the bead up about 3 inches..what a hit...needless to say I rode home on a flat and a stalling problem..should have used the sled today thanks guys BTBG
