    It could be something stuck in the float valve causing it to flood. Also, make sure that the float doesn't have fuel in it, causing it to sink. This will cause your mixture to go extremely rich, hinder performance, and leave an oily mess.

    Check your case gasket and that all the case bolts are still in place as well as head torque. If the oily mess isn't from the exhaust it must be something loose.

    Great feedback, RIOT are you running the breakin oil mixture still? Mine would blow oil underneath during breakin, then leave a quarter size drip under the exhaust when parked. It slowly got better then went away when It was OK to switch the oil mixture.___Or___ by chance is your mixture in your gas storage can incorrect?
