Thanks Jon for loading picture, new on here and will try to figure it out, if not to bad for me.
Anyway I bought this from my foster father back in 1976 and have carried it all these years, Yes it does have a serial number of 9000S9.
I taking a wild guess and saying the (S) might mean special & the 9 is number of frame, surely there are not 9 thousand of these frames or there would by more of these floating around.
I had to do a repo from a shop in Michigan
as they wanted this bike to disappear into their greedy paws,
Foster father came to help on a house I'm building about 2 years ago now,
he took it back up to Ohio and had a guy Tom Bibish get it running. All I can say is TOM is a non caring individual and if I can figure out how
to get pictures loaded easier you can all see just how sloppy this guy's work is.
