If you're looking for a start to your winter projects, I have a 1973 CB350 frame and swing arm for sale.
Also, I have a CL350 roller, in rough shape, no seat, no pipes, dented tank. If you're interested, email me and I'll get the year of mfg. from the head stock sticker. I'd say it's a 50:50 project between rebuild or breaking it for parts. No ownerships, got them horse trading over the years.
Email if interested: pwcowan285@gmail.com
Thanks,
Patrick
