I sprained my right knee over the summer and as a result sold my '73 850 on to a new owner. I picked up a '76 GL1000 GoldWing in really good condition to be able to ride without having to kickstart. I've joined a couple of GoldWing forums for advice & knowledge. Over on one of the forums, a Dutch owner of a '75 GL1000 recently restored it, chronicled on this link. Admittedly, the bike was in pretty good condition when he started, though I believe he said it had been under cover for 32 years. And only down in the middle of the post does he reveal that he's doing this at age 71. I thought that some of the folks over here might appreciate the effort.
