Default Oil leaking

Just curious what your guys thoughts were on oil leaking back out through the air filter. I have heard of others having this problem but I'm not sure if looking at the crankcase hoses is the problem solver here. Thanks!

What year model and miles? There are several reasons for this. The problem I mostly run into is bad umbrella valves in the rocker box. Late model Harley s stock from the factory from about 93 up do not have crank case breather hoses and breath through the heads into the air filter box.
