1973 Yamaha RD350 Liquid Cooled Engine Upgrade

This 1973 Yamaha RD350 is a father-son project featuring a rebuilt Canadian-spec liquid-cooled engine with less than 50 miles, a 6-speed gearbox, and numerous performance upgrades including Mikuni carbs, Factory Pipe exhaust, Ohlins rear shock, and FZR600 disc brakes. The build includes XS400 forks and wheels with new Shinko tires, an SRX600 swingarm, and a CDI ignition upgrade, all finished in bright yellow with iconic Yamaha decals. It has a clean California title, runs strong with no leaks, and starts easily, though the XS650 gauge cluster does not reflect true mileage.
