Don't you guys think that any good thief would be parting it out or changing the vin right away? Who the hell is going to steal a bike and then go ride it around with a hot vin, looking exactly how it did when they took it? Good luck, but it's probably being stripped right now... probably some fool who wrecked his own gixxer 1k and wanted a new one to put his vin on, change the body work a little and bam.. new bike for the thief.
If you keep it locked in a garage though, that is scary. How did the thief get inside? There might be some chance he left fingerprints.. very longshot, but the police can dust for em.. might work if it's obvious where he came in through, if it was a forced entry they know right where to look for prints. Someone who also watches you come and know - in order to know what is inside of that garage, and know when it's there. Could even be some bastard living in your complex who did it, or phoned in to the thief to let him know it was there for the taking. Sounds shitty - hope insurance covers it fully!
