Here’s what I came home to...

Mini Bike & Go-Kart Parts

Very nice Dave !

All the hard to find parts are on there too...gas tank, sissy bar, exhaust extension, TC cover.

And I've never seen that model Roper with lights !

That looks like a keeper to me.

Enjoy it.
Great find. You got a good friend who knows you well. I have its little brother, basically the same bike with a 4 hp small block and engine mounted gas tank.
And yes there were sold as street legal and are advertised as such in the catalog. I have a copy of the original owners manual which lists DOT mandated stopping and acceleration data.
