I recognize this bike. I restored one about a year ago and sold it. It was hard to peg the year because the catalog site didn’t go back that far. I dated mine to ’79 which I ‘think’ might have been the first year of the 1000. It’s not as spectacular a bike as the later 1000’s, but it is a real workhorse, do-anything bike. That’s what I remember most about it. Although I found the brake boss mounted racks a bit squirrelly.
