Just been through this getting my 2011 8V registered in NM. The plate under the tank is not the "official" VIN location. It is on the neck. It takes a good flashlight and two people. Start by looking from above. If you turn the handlebars just right and hold cables and wires away as much as possible you can see part of the VIN #. Then get on your back underneath and do the same and you will be able to read the rest of the numbers. PIA! Was lucky here to be able to a private for profit tag office. The employees are much more motivated than at the state offices but cost you more. They were willing to go through the contortions.
