Several threads already exist discussing this oil leak. Search
"air filter oil leak" will get several hits.

Go to the dealer and have the parts guy pull up the exploded diagram of the SE air cleaner kit.

There are two little rubber thingies that fit on the oil breather nipples and will direct the oily effuse from the oil breather into the airflow going into the breather. This should stop the problem.

Buy two, they are about $10 each.

Other fixes include running a half quart low on oil, and not "getting on the gas" until the oil has reached full operating temperature.

Also search, "oil carryover" or "puking"

You can use sanitary napkins and change them every month or so. Some Evos and Twin Cams puke oil, there are a whole host of reasons for this.

Every 28 days on average

Is it motor oil or the red K&N oil?
Is it a Sportster or a big twin?
Ness Big Suckers have this problem on some Sportster's, not sure if they corrected it on later models. I have not had any issue's with them on either of my TC's.
