You tried jumping it, or starting it with a fresh battery, and it just clicks? Starter relay is bad, or your starter motor itself (most likely the relay). A way to verify this would be to push-start the bike. Put it in first and hold the clutch in while pushing it up the street. Dump the clutch with the ignition on and if it starts, or tries to, everything else is working OK.
I live up in Simi and if you like I could take a look at it but not for a couple of weeks.
