After a 3 1/2 year restoration I finished my bike. Its a numbers matching 1970 750S. I did everything myself. Even the paint. Some upgrades include modern style Cush drive single axle rear end. Pazon, Podtronixs, Mikuni, Rebuilt tranny with new bearings and seals, New pistons and rings , rebuilt head, new isolastics, new wheels and tires, basically EVERYTHING has been reworked, upgraded or polished. All original take off parts are saved including yellow tank and side covers. Thanks so much to this invaluable forum for so many helpful tips. Kem Poyner
