I think that transmission would be difficult to adapt a bicycle. The shaft that carries the output sprocket is too close to the case. My chain drive reduction that came with the Gasbike $199 four stroke kit has a shaft that reaches inward from the case about 3". Even then the engine mounts on the left side of the engine are almost flush with the left edges of the seat and down tubes. With that sprocket on the cheap reduction you'd have to move the engine quite a ways to the right making it difficult to clear even the widest crank even if you bent it outward. In fact I had to heat and bend the wide one piece crank about 1 1/2" wider on each side to work with the Gasbike kit.
