Oil in the air box

[Duck07]

Hey guys Duck here again from TouringAZ and I have a quick question...I was taking apart the bike for some maintenance and painting and I noticed I had oil all over the throttle cables...I took off the top to the air box and I have a small pool of oil at the bottom under the filter as well as the filter is all wet with oil...I know you oil them but this looks like straight oil from the bike...I have no idea what or were this is coming from can anyone help?
