Revs that hang before dropping are typical of a lean mixture, put a few more miles on the bike and see if it still does this. If so, then you may need to tweak the mixture screws or look at your jetting.

And +1 for the carb sync. My bike was running like crap, and when I removed the carbs I could visibly see the sync was off, which meant that it was WAY-WAY-WAY off..!! Put the carbs back on the bike after a thorough cleaning and valve adjustment, and after the sync (so nice and easy after coming from an I4 and I3) the motor just started purring.

Now that you have a spare set of carbs, it would be good to have 1 set configured with stock jets, needles, etc....the spare you can use to experiment with tuning aspects.
