Great idea. You could look into buying a wrecked big twin for the drivetrain and title, and theres companies out there like drag specialties, CCI, and Paughco that make and sell frames and frame kits that come with numbers on them and certificates of origin. Check with your state on whats needed to do a kit built bike, similar to a kit car in registration i am sure. But if you have a title for the vin on the engine block, and certificate of origin with the frame numbers, it shouldent be too hard. I remember complete roller kits minus engine and trans in the drag specialties catalog years ago. They had options as far as wheels, forks, fenders, tanks etc, some kits came with wiring harnesses too. Frames, and sheetmetal all came raw steel or transport primered, a veritable blank canvas for how you wanted it to be.
