After my bike sat for about a month it is running on 3 cylinders (other than some backfiring out of the 4th). Also, when It was sitting in the garage warming up I noticed quite a bit of fuel leaking out of the exhaust on the dead cylinder under the bike. It seems like that carb is just dumping fuel into that hole. Has anyone else had an issue like this? Anything I can try before I take the carbs off of it and tear into them?

This certianly sounds like a stuck open needle valve. Sometimes a hard rap on the float bowl will cure it. Plastic headded hammer or the end of a screw driver has done it in the past. BUT----- if it's really stuck or has dirt in the needle valve you may have to pull the float bowl---- much bigger job.
Good luck,

You can also try and open the drain line, then turn the key on to cycle the fuel pump and see if you can flush any accumulated crap out of the bowls. Did you check for good spark on that cyl too?
