Oil Out of the Air Cleaner...

Oil Out of the Air Cleaner...
So, I get some oil out of the air cleaner when I ride her for any length of time at speed (I was cruising at just under 80 for about a half hour...). I've heard a couple different theories, but I'm not sure that I have a problem, per se, or that I really need to do anything about it other than wipe the small trickles that accumulate on the rear header and on top of the cone from the dripping.
Still, I hate to leave well enough alone... I am contemplating a re-route to either a catch can, or to a mini filter. Don't think its enough to fill a catch can over one "season," but I had one on my Buell (and on my old race bikes) and feel much better about that than a straight atmospheric dump (only just so)--in any event, much better about it than feeding it back into the intake stream. I have an Arlen Ness Big Sucker Air cleaner, which may be contributing to this "issue."
In reading about it, I've read quite a few Twinkie owners do some sort of mod to accomplish this and some people even sell a "kit" to re-route. Are there any evo owners here that do something similar? What did you do to keep the oil off the rear header/from dripping? TIA!

big power motors are not driven like a stock one every one turns the throttle and what we do in the shop, is to send the vent fittings to a T all with 3/8 hose to the end of the rear fender bottom - and let it vent away from anything on the bike
one guy took the hose and layed it over the top of the tour pack - that is not exactly how i had envisioned the install of the hose but it works for him i guess

You don't have a problem as such, other than the symptom of EPA regulations that require engines to ingest their own fumes, which then condense inside the air filter housing and make a mess. My lovely S&S 107" does it too, so you are in good company. On my original engine I installed a small air filter on the breather hose and located it under the seat - where it also made a mess! John's suggestion will probably do the same over time. Choose your poison......
