Impound lot: visit weekly.
Put ads in craigslist advertising it was stolen in the wanted an motorcycle for sale column.
Put out flyers in the local coffee shops, college dorms.. whatever.
Be patient,, it may take a few weeks to show up..
Also all readers should take photoes of their bikes, and record the vin, frame and engine nos. in their records.. the police will need those infos when your bikes inevitably get stolen.
