Hey all

[thednf]

Long time mechanic and tinkerer. Recently inherited an attempt at a motorized bike. Looking for help to figure it out most specifically what the manufacturer is so I can get info on the motor.

Here are a few pictures, as you can probably tell. I'm looking for parts or at least the manufacturer so I can find some and or any schematics or drawings for.

Looks like the basic generic 66-80cc

Most parts are interchangeable with differences in con rod length, piston pin height.
and cyl stud DIA, Inspect your engine
To your left you will see BikeBerry and Bicycle Engines.com they will have parts

There is no service manual that I'm aware of
