I've lurked here. I've used your links to PDFs of Honda manuals. I figured I'd sign up.
This '75 ran kinda almost when I got it for a bargain price a few years ago. Once sorted out, its reliability has just been stellar. Last year my "main" bike was getting some new innards when I needed to be elsewhere so this one has done thousand-mile days several times.
Now THIS one needs some new innards, but not much. The valve seals leak on 3 and 4, and the head bolt covers were spraying a bit. But it's opened up and I'm inspecting and measuring and I figured I'd eventually have a question. It's a solid bike and deserves a freshening-up.
EDIT: I have the same internet antenna as the NY billionaires down the road, but that doesn't mean I have decent service. Your phone certainly browses faster than anyone here. Just don't expect lots of photos from me or expect me to have seen any videos. Thx.
