Anybody know the stock h.p. on these? Are they pretty fast? What other sleds would they beat? Top Speed? Im just curious cause i picked one up a little while ago.I cant wait to ride this winter.Another thing i was wondering is I was thinking about re-gearing for more low end. Ive been hearing that if I drop a tooth on the small sprocket i will gain more low end and keep close to same top speed.Is this true?Does anybody know the stock gearing and width of the sprockets?Sorry about all the questions im just trying to get some info before i tear into it.Thanks for any info.
