my sled goes like mad when it's on the trail but as soon as i go in the powder it seems to bog out any suggestions??

its cause of the snow loose snow you have less traction and on hard packed snow it will get more traction same thing happens to me or it might be something will your sled? thats my .02 cents

for max power your jetting needs to be correct, if you are not experienced at reading plugs, i would suggest having someone who is help you. other things to check would be the clutching and gearing.

well i got a 600 summit, and i had the same type problem i think you have. The sled used to blow a spark plug then i would run on one cyclinder, luckily nothing bad happened, anyways i got a new set up plugs i ran 8's rather then 9's, and got it leaned out, so far i never blew a set of plugs.

NLBurden · 01-16-2008, 03:42 PM
