Back to reassembling the '80 so it can be sold as a survivor. I switched out the fork tubes for a set that were a whole lot less rusty.
Realized that to pass Ontario fitness, it would need a chain guard, so back to the parts storage, selected one that i was not saving for a project and determined that it cannot be installed without removing at least the shock, but better the wheel. Turns out the axle is frozen into the hub and all manner of special oils, balms and pursuasion would not free it. Fortunately, being a Special, there are the stops that can be removed so the wheel can come out with axle intact. Apparently it was designed so that the wheel could come off without removing the exhaust system, but by then, I had that removed as well as the fender, grab bar, taillight and so on. Once on the concrete, the axle, properly supported, drove out, but took the sproket side bearing as well, and the axle was still stuck in that. Back to the shed for another wheel.
But all is well, I am now back to where I was 2 days ago.
Tomorrow, figuring out why the clutch cable will not adjust. Bet it is in the side cover mechanism, but there is lots of help on the site about clutch adjustment!
