Is there any law against it.
When you transfer registrations between states you could have trouble. For VIN verification in CT they did not want to take the stamped VIN. We spent 20 minutes while the inspector looked all over the bike and telling me that there is a sticker, he has to find the sticker.
I spent twenty minutes saying I had no idea what he was talking about
and pointing at the stamped VIN. They finally took it. When I moved to VA, no one cared or even checked.
