The issue seems to be the combination of 2 different events, that caused this. First, the bike sat, with unknown aged fuel, for a long period. Second, during that period, you say you moved, and likely the bike was moved in a manner that stirred up all of the loose and microscopic rust particles in both the tank, and possibly the float bowls.
When you attempted to start the bike, these migrated into the low speed circuit. drain the bowls. Unfortunatly there is NO additive that will disolve the grit in the idle circuits, to get this part fixed requires disassembly, and agressivly blasting the circuits out using Gumout, and air. The Idle, if it was idling back before the storage, at the correct rpm, will return to where it was, adjusting the idle adjustment now will not acomplish the goal.
simply removing and reinstalling a tank on a bike that sat will stir up the gack enough to cause this syndrome. I always drain fuel into a can/jar/clear pop bottle when I replace the tank after a removal, to insure I get out the sludge that sits at the bottom removed before hooking the fuel line up to the carbs.
