I have a 74 cb550 onto which I am putting a 78 cb550 head cover. The rocker shafts on this new cover are very worn, so worn that I can feel a groove with my finger. I am not sure if that is a problem or not, but it seems like it.
As far as I can tell I have 3 options:
Find new ones... which will probably take awhile.
Have them welded and ground... which will probably be expensive.
Have a notch machined on the opposite side of the shaft and mount them backwards... which seems lazy.
Any thoughts?
