I have seen a cheap ($100) pocket bike engine, a 3pd autoclutch with left side drive, that could probably bolt up to a 44t standard sprocket. My only problem would be mounting. Can anyone help?
Here is the ad: pocket bike frame with running 110cc motor
The engine looks pretty standard, and is probably a Lifan-Type Honda 110 copy, (which I have seen people mount on old Honda Super Cubs). If anyone can help with a way to mount, post here.
