Holy S**T, I have owned this FP3 for 3 years and never knew about this. I ride pretty hard so went from standard to aggressive after 2 rides went to Race 1:1...Some of my Bro's could not keep up. Def recommend doing this for those that want to run their bike the way it should be...i'm prob a few years late on this..but hell..this runs solid with some V&H 2into1 Pro Pipes.
