Whichever way it makes the powervalves close; look to see which way you'd turn the arm to close them, that's the way to turn to put a little preload. You want them closed when the bike is not running, or not on the pipe. That tension keeps them closed until the governor pulls them open. The more tension, the longer those will stay closed, although I wouldn't say there is much difference.

Counter clockwise reduces spring tension, clockwise increases spring tension not sure on the exact setting I usually do one full turn
