It was a joke.......... I didnt know Kawasaki made a 3 cyl engine for bikes what year did they do this?. I knew of the Triumph Rocket III I dont keep up on Jap bikes much.
They made two a 250 triple and a 400 triple I had both. Main problem was rain if you had no mud flap on the front guard then the middle cylinder kept cutting out because of the plug getting wet. I can't put an exact date to it but I think it was late 70's early 80's.
