Everyone says I should get a race manual if I want to start working on my sled myself. I have friends that know all about sleds but getting their time is a pain in the "edit for bad language" so I darn it, I want to do it myself. How detailed is the race manual??? Does it show how to rejet and take clutches apart. Ive seen clutches taken apart before, tore down my old MXZ 440, but these new clutches are something else. Theres no snap ring. So Im just wondering how useful one would be for a guy like me before I purchase, thanks.....
