this is in behalf of a friend of mine that has a 2005 road king that has only 15000 miles on it that all of a sudden he's getting alot oil being taking into his air filter through the breather tubes , now i know having to much oil in crankcase can cause this by experiencing this myself, but that was checked and he put 1500 miles on it since last oil change and never added a drop of oil and it just stared doing this , anyone ever had this problem?
