I have a 75 CB750 - or rather some of it. It has a titled frame (title is from South Dakota) The motor is there, but stuck. I haven't tried to unlock it yet.
From my initial inspection, I think it's just locked up from sitting - but who knows. I've definitely started with worse.
It doesn't look to bad. No tank, I took the carbs for another project, no seat. You get the idea - project or parts bike at best. It does roll and I could put some of my leftover parts with it.
If somebody wanted to pay anything for it, I'd gladly donate all of the funds to the cause or you could donate what you can and I'd give you the bike. I'm in Denton, Texas.
It ought be worth $25, $50 or maybe even $100 to somebody. Anybody interested ? I'll even help you load it up.
