Re: Bimodal exhaust - can it be modified?
Turn the knob to hold the valve open then take one of the ends of the spring and move it two positions. If it stays open you are good. If the valve does not stay open, put the spring end back to the original position and go two places in the opposite direction. Very easy, and doable with just hands.
