RE: Oil from the air cleaner
There are a few different cures, I have a catch can with the pipes routed into it mounted by the battery on the Buell.
If you do a search for 'Oil puking' it will come up with many solutions Im sure.
But I have been told by a few mechanics that having this waste fed back into the carb , and on into the cylinder is not the best for the engine.

RE: Oil from the air cleaner
Yes, there is a cure but it is a little bit more complicated than you describe. The Sportster is designed to allow the engine to "breath" air and a bit of oil mist through two hollow bolts between the engine and the air cleaner. This mist is supposed to be sucked into the carb and burned in the engine, thus reducing emissions. Unfortunately, some of the oil condenses on the air cleaner cover and drips off the cover to be blown back under your right leg. I cured it with a "crankcase breather kit" for about $32 from the Harley dealer. You can get them on the internet also but I did not see them any cheaper. The instructions say it does not work with the standard old "ham can" filter cover, but it does. I do not know about newer bikes. I put it on my 1992 and I had to bend the two brackets just a slight amount that hold the back plate of the air cleaner to make it line up exactly with the face of the carb intake. Not a big deal and the whole thing took about an hour. The only difference you see is a chrome, U-shaped tube above and behind the air cleaner that attaches to the two kit-supplied shorter cylinder bolts. A rubber hose runs from this U-shaped tube to let the oil drip onto the ground. They give you a tube about a foot long but I used a longer piece of fuel line and ran it down and aft so it hangs in front of the back tire. The drip is very little and I see only an occasional drop on my garage floor. No more blowby since I put it on.

This may be as simple as not overfilling your oil.
If you have the oil level at the full mark it will throw a lot more oil out of the breathers than if it is about half way down or less. Mine likes to settle right at the lower mark on the dip stick. At this level it stops puking so much and the oil level does not drop from there. You will find lots of references to the oil levels needing to be lower than the full mark. If you have it over filled use a turkey baster to remove some.
May be a simple solution to your problem.
