How long was it idling for? NEVER leave any bike, especially a race bike, idling for any extended length of time. It could've got hot, and started to seize? Depends how long you left it sitting though. If it was only idling a short time before stalling, like Matt96xr6 said, check your clearances. If it got too hot, dump your oil too. :D

The '03's have been known to break the kick starter assembly, which could conceivably jam up the entire works by locking up the clutch hub. If the starter doesn't feel right, it could be worth looking at.
