Anybody here mess with Mopeds?

I have an unheardium (little bigger than a moped) stuffed out in my cargo container. It's an AMF years Harley Davidson Baja 100. Never seen another one like it nor is it listed in the picture books for Harley's. It's super tall and a two stroke. Been in storage since the early 80's. Has electrical for licensing and street use and an outer and inner rear sprocket with a dual master link to split the chain to further change gearing.
