Sorry, I just saw this post when you mentioned it, I did confirm that the secondaries do have the full range of motion and that the air valve only opens a quarter or so under wot. I pulled the plugs a few days ago and they were carboned up, so I cleaned and reinstalled them. I have not checked since, but I will be pulling the plugs today for compression testing so I will add what they look like.
