Oil in air filter

Anyone else getting oil in their air filter?

I have after a long hard ride with friends had it happen a couple of times - very small droplets gather at the bottom of the air filter case.


I have asked a few people who have advised me that it is normal for Harley's to do this as the 'crank vents through the filter inlet?'


As my bike is running fine I have accepted this explanation but really don't know why it does happen.
