He's got reed.spacers, pipe, geared down 1 tooth. Says he's gonna spank my sled fro start to finish. His is a 136'' longtrack. Mine has a new track turned backwards for better grip.with 144 woodys studs. Also has new belt,.and fresh clutches. Any need to worry? I already wooped his 04' xc 700. But people say this year sled is very fast. Only made it one year
