If you are starting from scratch and are set on using a bike engine, a large capacity shaft drive unit has to be the best.
� All that needs to be done, engineering-wise is to connect the bike shaft to whatever axle you plan to use, obvious eh?
If you already have a good chain drive lump and are set on using it, you have three options:-
1)� Convert an axle by fastening a sprocket to
���� the diff inside its housing.� It will run with
���� no oil and it will have to be tensioned.
2)� Find a bevel box from a shaft driven bike
���� and reverse it, then machine and bolt a
���� sprocket to that, driven off the output
��� sprocket on the engine.
3)� Turn the engine sideways and weld the����
���� drive shaft to the output sprocket.
��� There could be problems with cooling if��
��� the lump is air-cooled and also with the
��� exhaust which would have to be
��� routed differently.
