Port timing varies considerably from one motor to another.
The Plating on the barrel is very thin, if a barrel was to wear through the plating it is stuffed.
normally scoring of the barrel would be reason to replace it,
Ring gap is something I check on motors I build, but have not needed to adjust as it has always seemed sufficient.
