Like Ridin said, either get a clutch removal tool or a bolt. If you go the bolt route, you'll need a 3/4"-16 bolt and something to press against the crankshaft. I have a 96 Sporty 400 as well and just pulled my clutch a few months ago. I used the bolt method and a 3/8" drive 3" extension with a shallow 11mm socket attached to it. The other thing you'll need to do is brace the clutch with a pry bar, regardless if you buy the tool or make your own. Is really a lot easier than it sounds once you do it one!
