recently bought a '00 GS500. After getting it home and starting it up, after about a minute of idling, I noticed a puddle under the bike. After doing some investigating, I found that the leak was from a tube that comes out of the top of the engine, out the top of the valve covers. When looking over the bike when running before the sale, it never had any leak on it at all. This fluid that comes out of the cylinder head breather is a dirty clear fluid, first believed to be gas with a little bit of oil in it maybe. If anyone can help me out with what might be wrong or how I can fix this myself, it would be greatly appreciated.
 
Its the drool tube. Your engine evaporates moisture out of the oil and mists the oil itself. Both are vented out of the engine.

Some bikes vent from the crankcase to the air box, then to the drool tube. Your tube may be disconnected from the air box.

Most bikes have a cap on the tube that keeps the condensation trapped until you drain it at oil change.
 
The tube that comes from the valve covers is a breather tube.
I'd say it was condensation. When the engine heats up, the condensation inside starts to steam off. It cools back into water in the breather tube.
Check the oil, if it looks milky or you see water, change it.
If it looks ok, run the engine up to temp and then run it a bit more to boil out the condensation.
