Question about 2003 Harley Davidson XLH 883 Sportster
All Harley engines built after 1994 have been what we call "head breathers". In other words, the crankcase ventilation has been routed into the breather through the heads. The requirement of the crankcase pressures being released into the intake system is the results of EPA anti-pollution regulations. Harley moved the vent from the lower crankcase to the heads to decrease the amount of oil blown out by the ventilation system. But, there is a certain amount of oil mist present in the expelled air. The mist will collect in the breather over time and will eventually drip out of the air cleaner. Regrettably, this is a fact of life with a Harley engine and it's design and it is normal.
Now, you can clean the air cleaner on a regular basis to keep the oil out of the air cleaner or you can purchase a kit that exhausts the crankcase pressure (and the oil mist) somewhere other than the air cleaner. I thnk Kuryakin has a kit.

warm the bike up ,then if you look in between the rear wheel and the engine case on the left hand side of the bike (if you are sat on it ) on the underside you will see a black plate (part of the frame ) and it will have a black hose on it secured by a jubilee clip , remove the jubilee clip place a oil drain pan underneath it and pull the hose away from the frame and the engine oil will drain out .
hope this helps
