I'm in the process of changing mine right now. I took off the centre plastic panel inside (partly to ease access to the front clutch cover bolts, but I also had to replace an exhaust gasket that requires pulling the front header off), and took the battery cover off too. Once you do that it's easy to get at the clutch cover to get it off, but now I'm stuck wondering how to get the belt off without pulling the clutches. Not a ton of room to work with in there. Hopefully someone who has changed a 1000 belt will chime in!
