I feel the pain, of the OP, specifically in my ears. However, if you own a Harley Davidson you must understand that the bike has valve train chatter. I started with a Honda VTX 1300 and it was quiet, but it wasn't a HD. Harley's are a snowflake, each one is different. I have a 2014 Ultra Limited CVO and it is much different (better) than my Honda. When I first bought it new, it was relatively quiet, but not as quiet as my Honda. However, the valve train chatter is noticeably louder now, especially after changing the cam to a SE585 and every other component from the SE high capacity oil pan to the SE rocker arm to SE parts. If you begin to see abnormal oil consumption or your fuel mileage has changed considerably, then you should take notice.
