If you want to make it street legal it is a lengthy process and you must save all your receipts so that you can present them when you take it for inspection by the state police as they are the department responsible for D.O.T. compliance. It would need to have hi/low beam head light, turn signals, tail/brake light, a plate light, mirrors, horn and D.O.T. approved for on road use tires. It is over49cc/2.5 hp which does not allow for it to be considered a unlicensed scooter/moped for street use without an endorsement on your driver's license in any state.
Once you have made all the appropriate modifications to make it street legal you need to apply for a builder's title and this is where your receipts come into play because you have to verify every component on the bike's origin. As long as it passes road worthy inspection the police give you a form you take to the BMV and they will assign a VIN and you get a VIN tag that you then have to affix to the frame along with a motorcycle plate. The receipts also are how the insurance company will assess a value for coverage.
Now that all of that is out of the way it would probably be cheaper and faster to just pay your fine and then keep the bike off the motor-ways until you have made it legal and plated.
