This moped has grown from boy to man in 4 weeks. I welded in a top tube to make the top tank fit, and welded a solid bar across the foot pegs after the original one snapped in half. painted it all up, and reassembled with express parts from 3 different models. I hacked the stock header and welded an expansion chamber on to it. ...................................................................................The Specifics: 1981 Nc50 with a Nx50 belt drive transmission. fresh fat slicks. 70's Yamaha dirt bike tank. 70cc Dr kit with custom intake and a 19mm crab.
