Mine was an 82, 750, with Hitachi Carbs, and and electrical problems that would have made Lucas blush.
After pulling the head-light, and fighting with enough wires to light the Rockefeller Center's Christmas Tree - that the previous owner had obviously fought with before - I took it to a shop, and let them deal with it.
Other than that, and having to push-start it most of the time, it was a wonderful bike.
Oh, yeah...When I traded it in, the dealer's shop mechanics weren't very happy when I PUSHED it through the doors. It was the first time I ever heard a group of guys groan in harmony (not a pleasant sound).
