I have had this bike since 1974 and it has been several colors and shapes but has been like this since 1986 for the most part. The frame was stock but has been modified a bunch. The tank under the seat is a Falstaff Pony Keg and still has the tapper in it. The battery and other electric stuff are hidden inside. It still runs like a 900.
