Greetings,
82 cbx here. I seem to have a squealing tach cable /drive issue. I replaced the cable then lubed with dry slide and installed correctly. It worked for a while, then started squealing with an intermittent tack presentation like the cable end in the tach housing was skipping/slipping. No leaking at the valve cover fitting. Can the drive unit in the valve cover be at fault ( I have not had the vale cover off for some time) or is there a quality issue with tach cables?

Thanks.

Check the alignment of the speedo unit at the wheel. Once i didn't align it properly so the cable wasn't straight and it was noisy and tach needle was jumpy.
Drive unit can be taken out without taking the valve cover off but i doubt it's that. You'll most likely need to service your tachometer

Oh, and check cable routing too! There should be proper cable routing in the manual

Worst scenario would be that the holder for the tach drive on the cam bearing is damaged. that happens, when the valve cover is being removed without taking the drive out first.
