Hey guys! I'm getting back into the whole snowmobiling thing and I would really appreciate some help with setting up my clutching. I bought a 2004 800 mountain cat and will be riding Iowa and heading out to the mountains this winter. My question is...what would be a good selection of springs, weights, and helix's that I should keep in my toolbox and when or what altitude they should be changed? The only mod the sled has is a mrbp can. Any help would be great! Thanks!
