you can make an uber v , with a medium from from 99 with no mods to the frame at all but medium frames before this date and all large frames need you to re position the shock mount hole on main frame , this can give you a true 6 inch plus rear travel, mines a medium 99 so no mods just the swingarm needed , all small frames can be made into an uber lite , which is just the jekyll/raven rear swingarm and gives you 4.5/5 inch of true travel as they only have a small tab shock mount. they really do make a great bike
