    How to tighten Kawasaki ultra boost control valve

    I notices my ski is only turning 7450 rpm. My boost gauge is only hitting about 13 psi.
    My question is how do I tighten the boost control valve
    I tried but it just keeps spinning when I try to tighten it.
    Thanks

    I run a block off plate but you should be able to tighten by turning the nut that simultaneously turns the screw,with the nut all the way out I'm able to push the valve with the screwdriver(pic2) possibly escaping boost,turning the nut and bolt the other way and shortening it's length I can't push the valve what's so ever with the screwdriver (pic1)

    if you can't push that valve open with a screwdriver then it's probably the tightest it's gonna be..
