I think what I would like to do with this engine eventually is to build some kind of Cycle-car.
I have had this idea floating around in my head since before I got into motor bicycling. I actually got into motor bicycling so that I could gain some knowledge hoping that building this would maybe be the next step.
I put some pics below, I really like the 3 wheeled versions.
I want to mount the engine on the rear, behind the driver, most of these show it on the front.
The diagram is almost exatly what I want to build.
I even found an old Popular mechanics artical on how to build it!
