XP
I got a 2008 rev xp and i love it. i didnt have it stuudded last season but bought studs for this season im going to put them on my self. you have to buy the woody studs that are designed for it. they only recomend 84 for my sled any more they wont warranty the track. If you want some other ideas i work with goodwinn performance. They have alot of testing on the new xpand i value there opinion. if you do mostly powder riding than i wouldnt bother studding it save your money.But if you do mostly trail rideing than go ahead nothing is cheap thogh.
This is what im doing to my sled this summer.
Clutch kit,Jetting down on the carb by 2 sizes, check my oil pump setting, studs, drill out the outside of skis so i can have dual carbide runners.
any other questions feel free
