My buddy scored a 100-150 cc Lifan engine with a 428 sized sprocket on the engine. These are knockoffs of honda motorcycle engines.

He's already got a 40 pitch sprocket for the rear. I was thinking that we'd put a jackshaft in the middle, and step down from 428 to 40.

Ever seen 428 sprockets to buy? I don't know where to send him.

yeah ive onlt encounted 40 and 41, if you have some extra chain around try and see it the 40/41 will fit.
