I just installed another engine in my 75, and i guess removing and replacing the exhaust (with old gaskets) made it quieter for me too. I have had all kinds of new noises, and the reason i had to replace it in the first place was a thrown rod, so i am paranoid. Carb is very common, and the right side seems to always magnify sounds. Perhaps it's that fuel pump hanging out on the end with all that surface area...
To put your mind at ease pull your oil filter cover and look for fine metallics.
Or else primary chain noise could be with the oil getting thinner at warmup.
It must be pretty warm down where you are, and i've wondered why the gl states the same oil grade regardless of outside temp. (at least that's what i've seen.)
Though that rusty holed muffler you used to have is gonna change up your carb settings. You could open some of the carb sync vacuum screws and see if the knock changes a little.
My 2 scents. (gas and dead bugs.)
If Goldwings were whiskey they'd always be served neat.
