A couple months ago I picked up a couple of frames and motors on the cheap with several boxes of parts. Finally got around to looking at the years. One is an 83 and fairly complete with a decent motor but needs a lot of TLC. The other frame is painted puke yellow and looks to be an early XS1 with a newer 80s engine half bolted in.
If anyone is looking for an XS1 frame or parts, hit me up and I'll see what I have. Any reasonable offer won't be turned down. Can post more pics if needed.
