CB550K - engine rebuild (partial or full)
Erny:
Ignition is another story, I'll check that too.
But first (and this is topic of this thread) I need to fix mechanical issues:
- camsharft/rocker issue
- potencially address lower compression issue
- rattling noise - primary/cam chain, tensioner
- gear box issue
Note: as pointed by K2-K6 an Trigger, stuck sprocket carrier does not "help" primary chain, so this needs to be addressed too.
Bryanj:
What gearbox issue do you have? Had quick reread but could only find it as issue
Erny:

K2-K6:
I remember that one, about the gearbox, that is.
In view of the cush drive possibly being stuck as recently discussed, I would be inclined to work on the wheel first as it can have quite an effect on gear change quality.
If you open it, the cases, and can't find any internal problems with the gearbox, it will leave you not knowing what could be wrong. It would be extremely useful to you for diagnosis to make sure the wheel is as good as possible first.
At least you can be sure you've eliminated the cush drive. They can have a surprisingly large effect for something that doesn't appear to do much.
Certainly you can re-test and see for yourself if you feel a significant change without touching the engine.
Erny:
With all respect - I realy cannot imagine how stuck cush drive can cause this??
