I'm going to check out a 1976 BMW R60/6 with a Thompson CycleCar hack. 46k miles on the odo. Owner says it's mechanically sound with no major issues. Asking $3k. I don't know anything about these old airheads and plan on taking it to my motorcycle mechanic to check out. After researching this bike, it seems like a fair price w/ the hack. Any thoughts on that? I'm looking for a sidecar rig so I can haul my 170lb Mastiff around with me. He's got some pretty serious separation anxiety issues, and I haven't been able to ride my bikes nearly as much as I would like. So I figure a sidecar rig will help me ride more while being able to bring my buddy along for the ride. Anything in particular I need to look for on this bike? Is it a fair deal? Any thoughts and/or opinions would be much appreciated.
