The oil is coming from the crank case vent reservoir which is a little rubber "cap" (for lack of a better term) that catches the small amount of oil vapour that comes out of the crank case. It is located in the air box and needs to emptied on a somewhat regular basis.
Since you said your bike is new to you it probably wasn't emptied in a while, was full, and leaked out into the airbox.
Take that cover off and take a look you'll see what I mean. It's located near the bottom
