I bought a 1975 Goldwing cheap in 1983, it had been thrashed unmercifully by the previous owner, and looked it. It had RD Yamaha mufflers welded to the Honda headers, horrible king/queen seat, ugly barn door fairing, etc etc.
I spent my $2K tax refund (back in the days when I used to get one) replacing the complete exhaust system, seat, paint, battery tires etc, then found out there was a major problem with the charging system. Replaced the alternator rotor and stator, regulator/rectifier, then the starter motor crapped out. This wing must have been built on a Friday, it was just one thing going wrong with it after another.
Sold it and bought a 1975 Kawasaki KZ900, which was a much better bike all round. I'm sure a "good one" would be a great long distance tourer though, as long as you stay on freeways with only long sweeping bends, and stay away from the twisties, they're not big on handling either. Cheers, Terry.
