Ok, if your starter turns the motor over, and it will run a little, then the starter is working and you have spark. Open the drain screws on the bottom of each carburetor, and see if gas drains out. If it does, you have gas in the carbs. Assuming you have compression, I'd say there is about a 99% chance your carbs are plugged up with what used to be gas, and will need to be removed, disassembled, and thoroughly cleaned. If the caps have been removed from the idle A/F mixture screws, remove the screws, and the springs, spray some Gumout in the holes where the adjustment screws were, then spray a little WD-40 on the adjustment screws, to lubricate the threads, and prevent the o-rings from getting damaged. Put the screws back, turn them in till they seatlightly, then back them out about 2 1/2 turns, and see what happens. Hopefully it will now idle. If not, you will have to go ahead and clean the carbs.
BTW, if the hose you put back connected to the back of the right side air filter housing, it was the carb float bowl vent hose. Go ahead and remove it, and blow into it. It should not be plugged. You can leave the end unhooked for now, it is supposed to be vented to the atmosphere. The air filter housing just serves as a holder for it. You can even get a longer hose, and run it out the bottom of the bike somewhere. Jerry.
