Glad you liked it. The Pre-75 Minibike class is a hoot!
My bike is a Mini-Gote, probably late sixties vintage. It has a Briggs motor, K & N filter, different shocks and good pegs moved back on the frame. It also has fenders from a Trail 70. The rest of the bike is pretty original - front end, frame, wheels, jackshaft, torque converter, seat and sprockets.
Check out the second moto in a separate clip. In both you'll see ace Rupp pilot Matt C battling for the win... Briggs vs Tecumseh !
