    You need to depitch your prop or add more power to get the rpm's up.
    What riva air intake are you using? 3in front? If so you need to ditch that for a 4in front air and also remove the flame arrestor from the manifold.

    Speedskixp told you exactly what you need to do...

    Sell your riva 3 inch intake and get a 4" Kanaflex Intake.

    Remove your flame arrestor...read up on the forums on how to do it yourself. Riva sells a kit for it.

    And finally after you do those mods check what your rpms are at, should be around 7800ish and then depitch your prop to get to 8100 RMPs.

    Good luck.

    you asked and you received an expert responding. You should listen and show some respect.
