The one shot I got of Rainey's GPZ 750 before the camera went on strike.
Honda came out blazing in 1983 winning the first 6 races of the new 750 sized Suberbike championship.
Kawasaki was running their air-cooled 2 valve against the new water-cooled 4 - valve V-4 Honda. They got Rob Muzzy to up the horsepower and then Rainey won the next 6 races and took the championship.
Check out the details, not a run of the mill Kawasaki. Twin plugs,dry clutch,etc.
