I had the same problem on my 06 ultra with a K&N filter, after a long ride a few drops of oil would appear on the little womens jeans. I tubed the breather vents into the intake, figured the vented mist goes in there anyway. Problem solved. Did that about 10K miles ago. Plugs never changed or showed oil.
Yes this will work BUT many here KNOW that the added Junk (moister and oil) will add to the build-up of carbon and can be an earlier Death to a good running motor.
I have NOT done my 09 King yet (venting to the ground under bike) BUT want to when I find the time to get off it long enough besides Just changing the fluids...
Nice here In SE Az.:s

You the MAN,
I have the same little markings and must admit that I do ride it a little harder a times. You think I can expect it to get more noticeable as the miles grow? We need to meet up for another ride some time this year! Our local HOG Chapter's doing Tombstone but the YF and I will be unable to make the ride this year. Thought about you WAY over there anyway! Still got those sparklely shades? Ride Safe! Steve
