Throttle Adjust

How do I know if my throttle is adjust properly at WOT position on the vz225? I looked at the throttle cam but not sure where the cam follower needs to be at WOT. Also there is some sort of limit switch (??) on the back side of the cam near the end of travel. What is this for?

Remove the air silencer and move the throttle to WOT, then visually check the throttle plates for being 90 degrees to the closed position. You don't want them less than nor more than 90 degrees.
