Subafly-
That's the carb vent hose. It's job is to make sure that hte carb bowl remains at atmospheric pressure so that fuel will flow. When it get's blocked off, the engine starves for fuel and runs like crap. There's a mod (T-Mod) to fix that, but that's another story 'cause it ain't your problem today.
If stuff is coming out of it then your inlet valve is definitely stuck (or the floats are gas-logged and won't float anymore) and she's floodin' like the mighty Mississippi. Best bet is to remove the carb and give it a good cleaning.
You may be able to get away with removing the float bowl and jiggling things about a bit, or you might even set thing right by tapping the bowl with a screw driver handle. But, it's a 10 year old bike. If the carb is in a state where the inlet valve is sticking, the rest of the carb probably isn't that far behind.
While you're waiting for your Clymer's to come, you might want to look at this site:
