So, I was riding my bike earlier and noticed this bad sound coming from it whenever I would slow down.
I got it home and started checking things out.

Now, a little history on the bike.
Since I got the bike about five months ago, the coolant has been this nasty milky color. I never really thought about it being oil, I thought the fluid was just really old. The other day, I got my oil changed by a local cycle shop. They never said anything about the oil looked bad, and it seems like if it were a mixture, they would have noticed.
(I don't think at any point they looked at the coolant.)
Also, it may be completely unrelated, but since I've been riding the bike, it drips oil down the crankcase and has covered my left shoe in oil. It's a very small leak, but over time it's built up and ruined two pairs of my shoes.
Anyway, shortly after that, my radiator hose went out. The bike may have overheated a little, it was dark and I couldn't see the gauge.
I got a new hose, replaced it, and flushed the fluid.
Since then, it's been leaking the same milky colored stuff on the left side of the bike. Leaving fairly large puddles wherever I parked. I kept an eye on the coolant, it never seemed to go down, which was odd. I found the coolant was dripping out of the overflow hose, so I thought it was just because I would have the bike tilted to the left on the kickstand.


Back to earlier, I get home to check on the bike, check the radiator fluid, it's full to the brim of this overflowing milky solution. Look at the temp gauge, and it's over 3/4. I turn the bike off and check the oil, it was DRY. I cleaned and checked the dipstick several times, always came back dry.
I used a flashlight to look into the hole, I could see no oil, at all.
I'm thinking the oil got into the coolant, but if it was the headgasket, wouldn't coolant have gotten into the oil as well?

I read somewhere it could have something to do with the water pump gasket.

I really need help on this, Let me know what you think.

 

I think thats BAD!

 

Head gasket has gone, I'd say.
You need to stop riding it IMMEDIATELY or your engine won't be worth fixing.

 

Then wouldn't there be a similiar mixture in the oil?
Instead, it was just dry. No oil, or coolant mixture. There was nothing at all.

 

Not necessarily - depends where the gasket has failed.
I've seen both 1 oil in the water and 2 water in the oil.
Whatever you do, I'd suggest dropping all the water out, refilling and replacing the oil. Run it just to circulate the oil to the major components If the water gets to your bearings, and your crankshaft you're in for a full stripdown and new bearing shells. Not a good thought.
Then ask a mechanic but I suggest he'll give you the same bad news I did.

 

There are a couple of threads around here - but this is usually fixed easiest by replacing the oil cooler o-rings. This makes sense on our bikes because the oil cooler is housed inside a waterjacket that is filled with coolant. The coolant helps cool the oil. When the old o rings get tired and start leaking, oil can seep out into the coolant.

Get the proper parts, drain and flush both systems, and see if it comes back.

 

Here a link in one of the other threads like this where I posted the pics of the oil cooler system and how it interracts with the cooling system.

Anyone know how easy, or how much it would cost to have the Oil cooler o-ring changed?

 

get the header off, drain water and oil, pull it apart and replace - just unbolting things mostly.

 

+1 On AdrenalineJunky's response - usually it is just the O-rings for the oil cooler - the cost of these is negligible.
