-Also, the valve opens and closes with no issues by hand.....when I disconnect the cables to the butterfly and rev the motor, it still only turns the servo partially, not the whole way like when I put 12 volts directly to it.
-My theory is that the ECU is not sending sufficient power to the servo motor and therefore, it is not opening up the ex valve completely.......

The valve should start to open (Lift off the seat)at 4K RPM and open fully at 8K RPM
You need to check the voltage at the servo motor at 8K to verify your theory.
Also, check all the connections from the ECU to the servo motor for corrosion
Just thought of another possibility, the resistance value is not in the manual, but if the servo assembly was taken apart prior and if the feedback resistor gear was not set correctly then the wrong feedback voltage could be getting to back the ECU.

-Maybe a stupid question, but WFO should put the butterfly locked in a clockwise position resting against the stopper pin, right?
reason that i ask, is that the manual refers to a closed flapper valve at less than 3000 rpms, but shows a picture of the butterfly locked clockwise (Which I am under the impression is wide open), and fully open flapper valve when above 8000 rpms, but shows a picture of the butterfly locked in a counterclockwise position??????

Did you have any issues or questions adjusting it?
So are you saying that if you turn the valve full CW and start the bike it moves back CCW with small rev's? (way below 4K)
You should see the butterfly finding and pushing against the CW stop with revs under 4K.
