I had a Hondamatic for a summer. I traded a Suzuki 175 dirt bike for it. The lady that owned it wanted to get rid of it because it had a leaking cylinder gasket. I replaced the head and cylinder gaskets and put new rings in it and got it back on the road. It was the only street bike I had at the time but it was slow. Just judging by my 'seat of the pants" dyno the 550K I used to have was faster. I don't miss the Hondamatic in the least but sure wish I still had that 550K.
