starter chain slack?

what's acceptable slack? Looks to be about 20mm slack and just about to rub along the bottom.

btw, I like how the rotor of my 1966 CB77 has "Cb72" stamped on it

Dana, looks about normal, as does the "CB72"

Agreed. If the chain moves with the engine running then there's a problem with the starter clutch.

All rotors are CB72-stamped.

The one in my CA77 was rubbing on the bottom. I picked up a NOS RK chain and I'm going to use it when I reinstall the starter. The rubbing is on the slack side and only happens when the starter is running so I would think it's really no big deal other than a sign of stretching (or maybe sprocket wear).
