Doug, I really don't have but that 1 single - the 1966 S90. My 1973 DT3 Yamaha Enduro is single, but probably not what you were looking for. Bill knows I have a soft spot for the old Hondas. I've managed to find exact copies of the S90, CL175, CB350, CB500 Four, of those I had growing up. I've restored and collected several more since, but those will always have a special place.
Good luck this weekend on getting it started.
Regards,
Gordon
