On my 999 there are 2 hoses coming out of the front of the tank. Are they supposed to connect to anything on the bike or do they just pretty much hang there ? Can the just be removed leaving just the nipples exposed ?

For US models, they are connected to the Charcoal cannister.
For euro models, they just run tubes to the bottom.

Don't remove the tubes. It's for over-fill. You don't want to spray your bike with gasoline. Just Y the tubes and run them to the bottom, that way excess fuel leaves the bike with out touching the bike

If you are trying to figure out if your lean burn issues are related to the kinked hoses you can disconnect them for a test ride, but don't run the bike with no hoses. As pointed out you'll be puking gas on your bike.

If the hoses are kinked and causing a vapour lock just replace them with hose from a auto parts retailer.
