McQueen I spent close to three weeks trying to find a bike in the greater LA area, scouring as far as Bakersfield, SD and the inland empire. There just aren't a lot out there and when they do pop up, they are snatched up quickly.
Eventually, I had a non-running 75 750F with 18k miles shipped to me from Denver for around $1200. Bike is actually in great shape rust/condition wise, but is currently in a million pieces going through a complete rebuild. Having a running bike is great, but if the thing is beat to hell, I wouldn't do it. There are deals out there to be had if you are patient.
