Before I buy a bike in California here is what I usually do, assuming there is no pink slip/ owner title.
I first go to my local AAA office and tell them I'm thinking about buying a bike and here is the Lic# or Vin number. If I forgot to pay my membership, I'll ask a friend with AAA(America Automobile Association) to check it for me. This can only be done by walking in the office!
Three things may happen:
1-They tell me there is no existing registration/ no record. Great! This means no back fees or previous owner problems. I can register it under my name or fix it up and sell it with no worries! I sign a paper that says Joe Doe sold it to me for $50 or whatever, about $70 later I have a new title and Lic plate. I win!
2-They tell me there is record= non-operation permit, old back fees or parking ticket fees. Usually there will be fees to pay, I'll weight my options and decide if it's worth it or not. I buy cheap, so usually it's worth it. Or I might buy to just part out. You heard me!
A non-running bike that looks like it has been sitting for years normally means: the previous owner lost interest in it, otherwise he would have reported it stolen! I might try and locate the previous owner, if I have an address. Usually PO is not at address! I win!
California only keeps motorcycle records for 6-7 years before it drops them from their central computer. It will stay in the computer longer if it's stolen, has a non-operation permit or maybe parking tickets.
3-They tell me it was stolen. I'll ask how long ago! hahaha! I'll report it!
