:thumbsup: I will start by saying that I am one of those who loves the new intake filter system of the new bike. Also after adding an after market exaust I no longer feel the bike is plugged up. SO my question is. Does anyone have before and after dyno #'s of their intake mods?

As I recall, Ron from TUF racing posted up some numbers on the improvement from opening up the airbox several months ago...

As I recall, that involved an air box attached to one of his 60+ HP engines, which are considerably different in their air flow needs than the 50 or so HP stocker. It still wasn't a focused, before/after test of just the one mod, either as I recall.
