You know what's funny is that I make my own music videos from the trips that I go on and the footage has audio as well. I noticed that my rebuilt KX5 has a very "four stroke" grunt sound when I am lugging it and a "two stroke" scream when I am on the pipe. As I watch some of the videos, I catch myself wondering if the audio is messed up... really dig the KX5 and its versatility.
