Changed the air filter at 80K and wow did this need done long ago. This is what the air box looked like. Water and oil

The T fitting from the two tubes coming from the bottom of the air box. This drains into the top of the engine case.

I am in need of an explanation as to where all this oil and water is coming from. Any help would be greatly appreciated.

The oil came from the crankcase as the engine breaths. An excess amount of oil can be caused by overfilling. The water comes from moisture in the air that enters the airbox, i.e. rain and condensation. Be sure to drain the condensation tube on the left front of the engine.

Suppose to drain the tube at each oil change

The air filter not only has to breath in, but it has to easily breath out when the motor it is turned off too. If running in a damp climate, the moisture in "wet air" gets sucked in while running. When the motor is turned off, there's an increase of "wet air pressure" in the air box and it needs to immedatly vent out and escape back into the atmosphere. Basically, the air pressure in the air box needs to quickly equalize with the atmosphere. The dirt show evidance of an extreemly dirty air filter that has the ability for a motor to suck air through it going in, but the slime is evidance that once in it is somewhat trapped and can't equalize quickly when turned off. Over time that wet air condenses from engine heat and mixes with oilish gases and turns to a milkish slime.

At the very least, all 3 vent tubes from the rear case to the air box should be cleaned. Also the breather tube that ends near the left valve cover needs cleaned also.

The white goo is from condensation and oil residue mixing. This is normal on a bike that is ridden in all kinds of weather. The filter was definitely over due. The hoses are not drain hoses, they are part of the crankcase ventilation system. Make sure they are cleaned out and wipe down the oil residue in the box. If you remove the larger hose from the engine, make sure and route it back on top of the radiator hose and not under it. ?

Glad these dirty air filters getting replaced. I've got 26K miles on 2003 and perhap next summer I'll pull the top shelter.

In the meantime, I'll enjoy some wine . . .

26,000 miles on the OEM filter? You might have your own stash of M&Ms, jtdunc. Or worse. If your 2 ram air intakes aren't screened. Mine at about 27,000 original. Always worth another look.
