Leaking Fluid - any ideas?

So I just got my whizzer back from the shop undergoing a brake replacement. I'm not very well versed in working with motorbikes so I have a little trouble assessing what is going on with my bike. Anyways, I picked it up Saturday (today is Tuesday) and after riding it home and parking it, I noticed a leak underneath it. I thought nothing of it until that night when I moved it again and the puddle was much bigger. It's a neon-ish yellow fluid leaking near the carbeurator, but could be coming from the gas tank I think?

Any Ideas?

Did you stick your finger in the yellowish fluid? Smell it? Taste it?

It's Oil coming out of your engine breather which is a common problem on your motor.

Smelled the fluid, didn't taste it - had a cup of coffee at the time!

So, oil coming out of my engine breather huh... I'm going to explore around and see if I can find a schematic of the engine and hopefully not screw up anything too much.

Any ideas if this is an easy fix?
