I too had a CB350 for a while but never saw 60mpg, I tended to average 45-50mpg, the thing with synthetic oil is that alot of it will ruin the wet clutch of a motorcycle if it has friction modifiers in it, so just a word of warning, I've replaced two wet clutches for this reason.
But you are right, the CB350 has constant velocity carburetors, so a slight twitch of the throttle would make it open up the diaphragm and thus open up the needle for the main jet in the carburetor, dumping in extra fuel.
