Supermotard Vintage Mini

My buddy Len has this cool Rupp that he plans on putting Supermotard tires and rims on and touring the winding roads of the Smokey's brushing up on his skills before he commits himself to the race circuit. He has made many modifications already . The front suspension is all tricked, out and I know the gas cap is off an old Norton. He is waiting for the Supermotard tires and rims to arrive from the fabricator, he has a half helmet and bubble goggles that he cinch's to his head with an vintage elastic cord, I'll try to get more details... Any ideas and suggestions for his success are welcome. JW
