I have a 1981 CB750 Custom and the charging system I know is going bad
could it also cause a high rpm miss?
I've checked the plugs and they are in excellent shape I'm leaning
toward the carbs need work,I'm interested in what others may
think......

Yes!  It's one of the symptoms of the charging system going bad/voltage
dropping off on these models.

Your charging system problem is most likely the rotor.  You can get
rebuilt ones on Ebay for decent prices.

Before replacing the rotor, make sure the brushes are not worn out,
and also make sure the slip rings are polished and shiny, not all covered
with black and corrosion.

Brushes on these need replacement every 20K miles or so.
