I bought a new 09 Road king Classic, drove it stock for the first summer,(7000 miles) installed a stage one on the second year (SE air box, V&H monster ovals, and a TFI unit,(also put 7000 miles on it that year). drove the 3rd year and again put about 7000 miles on it with no issue's. Now last year I only put about 4000 miles but noticed small amounts of oil dripping out of the air box. Is this something I should be concerned about? I remember my first vehicle a 77 Ford half ton, I drove it hard for 7 years and it started to spit oil into the air box through the PCV valve filter, and it turned out to be caused by base pressure from compression slipping by the wore piston rings, but I had over 100 thousand on it. Starting to think about summer riding again and went to my local dealer today and order some true dual exhaust headers. can't wate for June and the first big trip to laconia with the buds.
