Did you just do an oil change? Chances are you have too much oil in there. There is what is basically an overflow valve that goes to the airbox. If the oil pressure is too high (due to too much oil, and then expansion from heat). The oil then drips out of the drainage hole in the airbox. Pull out your oil filter and you will find a small puddle of oil in there, as well as you air filter having a nice coating on it. To fix the problem, drain your oil into a clean container, then refill only until it gets to the correct level on the site glass.
