I recently installed the Burst series air cleaner kit on my "12" Ultra. I have noticed a few different times that oil is dripping out of the bottom onto the cam cover . When I run my hands down at he bottom of the air filter there is a lot of oil and grime. I had the bike tuned with a new SERT after I installed the new air filter kit and the bike runs fine. What can be done to prevent this or control so it does not keep making a mess after I have cleaned.
