I had always admired the ill-fated Yamaha TX 750 for its styling and innovative engineering. Unfortunately the factory had not foreseen the disaster that would occur when they designed a counter balancer which whipped the sump oil into a froth which in turn resulted in poor lubrication and engine failure. Yamaha nobly stepped forward and sent many complete engine overhaul crates to dealers across the US. Sadly, by the time the corrections had been implemented in the ’74 models, the reputation had killed any chance of recovery in the market.
I bided my time and eventually was lucky enough to find a healthy ’74 model and a very fine original ’73 model with excellent original paint, chrome, upholstery, and aluminum and a seized engine. Since my preference is for the ’73 styling I chose to rebuild the top end of the ’74 engine with NOS standard pistons, rings, and a careful valve job so I could have a beautiful and reliable bike to enjoy for vintage events. As a mechanical restoration would dictate, all fuel, ignition, charging, braking, chain and sprockets, lighting, etc. have been replaced, rebuilt and tuned carefully. The front tire is a new rib Avon Speedmaster, the rear is a Dunlop K-70 which both look the part. The chain is an O-ring. The chrome on the mufflers is excellent original with no trace of bloat or belling. The sound is a delightful gentleman’s authoritative tone. One might feel obliged to wear a linen suit while riding this bike.
The final picture is this bike's June 2019 appearance at the AMCA Nationals in St. Paul, Minnesota.
