look in the how-to section and they have a clutch kit write up on there, should be the same principle for the most part from that 4wd to a 2wd bike, not hard to do as well, i did mine bymyself without taking the entire clutch out, did it with it connected to the bike, got very frustrated a few times but just stuck it out...also i dont even notice that much of a difference with it on the bike now, and i ended up breaking 2 bolts in the process of doing it
