Nothing broken, and the lower piece of the forks is not too bad - but it was as I thought, the threaded stud inside it was Very rusty; I assume it was that rust that was giving me problems. But, I do have to find another set of wheels for a '72 CB500 - the ones I have are rusted over, and no good. Anybody got any they'd be willing to part with?
