Gary, where are you running? I do ECTA and Bub.
Bub rule book says 'Production class motorcycles shall not be modified from Original Equipment at time of
manufacture. i.e., frame, forks, gas and oil tanks, seat, front and rear lighting, fenders, wheels, brakes, air intake box and (unmodified) exhaust system.
Ecta says 'shall be equipped with full lighting equipment, frame, forks,wheels, brakes, gas and oil tank (if OEM), fenders and seat. The motorcycle must appear identical in all respects to the production model it represents'
Both groups require manufacturers documentation so they can compare to your bike.
If you are running for a record make sure your bike looks exactly like the pics in your documentation, repainting does not disqualify you though. There are some minor things you can do, check the rule book for exceptions.
Hope this helps
Bob
