Great info Lee. Thanks! I will connect the GS911 tomorrow and try to find that function. I assume the servo buddy keeps the valve fully open all the time. Any noticeable change to low-midrange torque?
Well in my case none of that stuff is on my bike so that is why I use a Servo Buddy. Since I have aftermarket pipes I have no cat or flap.
You can use the servo buddy and remove those items and the bike will not throw codes.
Again I have read of the pivot being frozen, the exhaust pipe being crudded up,and the cables frozen,
I notice none, zero, zip difference.
People always attribute the flap to back pressure but a lot of it's intent is to make the bike quiet at idle and low RPM to pass DB noise test's from what I have been told.
With no flap when you start my bike instead of the flap being 1/4 or what ever there is nothing so it is at it's loudest right at idle. No complaints from anyone around me on some recent rides. I was in front of someone who would have been honest no mater what.
I mean you can get real deep and get into cam overlap, and exhaust wave reversion and all the other science that goes into a exhaust, and valve opening and closing blah blah.
I know I would not buy a set of OEM headers to have it work and that is a fact.
