Moped Army

This info has helped to relieve my anxiety about getting my moped registered and dealing with the DMV. I purchased a Motron 2 days ago and prior to making the purchase, stopped by the DMV to see what needed to be done, as the seller told me over the phone, that he had no title, the bike had no plates, etc. The DMV gal gave me a gang of forms to fill out and said to bring the bike in for inspection...

The 230 form will make this process very easy. I do have a couple of questions though:

I was looking for the VIN on the bike and the only thing I have is a 4 digit number on the metal plate below the handlebars. Could this be the VIN???? I just got back from the DMV to see if the bike had been registered sometime in its 30 years of existence and using this 4 digit number, I was told nothing came up. The lovely DMV lady did not say if this was due to the number I had being wrong, or because the bike was never registered. SO - Should I only fill out sections A and D of the 230 form or still do section C as a transfer of ownership???

I want my contact with the DMV to be a minimal as possible and want to send in the 230 form today or tomorrow so that I can be riding legally before the winter sets in!!

Thanks!!
