I would try the bike out before making too many mods. Learn how the bike works. Then start adjusting. Probably wouldn't need it. Are you going to be doing a lot of trail riding? If you are, another option other than the new timbersled ski in a snow hawk ski. I can trail ride all day with that. May not perform as well in the powder though. I know two guys running a hawk ski and they like it on their timbersleds.
