I have a 2006 sporster 1200L with 10 thousand miles on it. I am having trouble with oil blowing out of the air cleaner. After about 150 miles the side of the bike is covered with oil. We have tryed running it a 1/2 quart low on oil that did not help. So we put on a big sucker air cleaner that helped, not as much oil on the side of the bike but still there. Not sure what next the bike runs great and no smoke out the tale pipe.
 
The only way to prevent this situation entirely is to install a crankcase breather system to vent the crankcase to the exterior -I.e. to the ground or a catch can!!

I did this on my 2008 Ulta with a 120r Crate motor and it worked awesome!!
 
Sportsters are noted for oil coming out of air cleaner, especially after highway speed running.
+1 on aftermarket kit to vent to ground or jar. If you vent to ground, be aware of location of vent tube - do not put anywhere near rear tire.
Maxi pad on inside of air cleaner will help. Remove and replace at every oil change
 
The vent will help BUT another thing is don't fill you oil full. Keep it bout 1/2 qt low. Have done this for too years with no problems including blowing out the air cleaner.

Besides for the good info already here.
Think the Sportsters require a 30 micron oil filter???
Not sure about the oil routing on a Sporty, but depending on that routing, it's possible that if you have a 10 micron/wrong filter it could contribute to the issues you are having.
 
if you have the the 2 breather tubes behind the air filter use a auto vacuum "T" and route it back into the intake
