vent hoses.. what it leaks..

I was putting my bike cover on my 2009 CBR600RR and felt oil like stuff on the kickstand. I cuss a bit and inspect... Looks like the middle vent hose is leaking something? Feels like oil and doesn't have much of a smell so i'm a tad confused? Was pretty sure one was for fuel.. but... this doesn't smell or feel like fuel. But it's all over my kick stand!

Has 1600 miles on it now and I just took it over from a guy who never did anything to it. I was planning an oil change but got lazy today.

Any ideas?

You have a fuel, coolant and oil overflow down there, its actually very common nothing to worry about.

But why would the oil randomly overflow? Reminding me I need to get off my butt and change it?

The 2 larger lines are actually Fuel tank drain hose and Fuel tank breather. The smaller hose is the Coolant overflow.

Fuel maybe coming out of the drain hose if you are filling your gas tank right to the brim.

Tenjin proably right. I pull off my sprocket cover today and there was alot of old chain lube on the cover and some of it looked to have dripped onto the hoses.
