Re: Two 66cc engines side by side?
I also toyed with twin China girls idea too. I bought the engines and two OCC chopper motor mounts. The mounts were trimmed and were meant to bolt onto a universal mounting plate. The engines were side-by-side and 1/4" apart from each other. A common jackshaft was to connect both engines' drive chains. Then, a jackshaft sprocket would connect to the rear 36t sprocket.
i scrapped the project because it was too wide. Also there were too many engine controls, two throttles, two clutches. Looking back in retrospect, the chopper motor mounts would need heavy gusseting. Vibrations would've been horrendous.
I'm glad someone else is trying to build twin Chinas.
