    Whats the continuous poping sound?

    I have added a engine tech 11.7psi wheel to my stage 1 mods.
    Just saving up for an ECU upgrade.

    When on 3/4to full throttle the ski starts loudish poping bla,bla sound from the back or what seems like the back of the ski.

    Is this the rev limiter or the boost limiter?

    Will this harm the ski or be ok till I get the ECU done?

    Cheers guys.

    you might want to open up the leading edge of that prop to a 14 to lower your rpms. you trailing edge is pretty tall with a 26.
    that is my .02

    First time I heard it on my ski I changed my plugs. Almost sounds like a miss.

    Get her off the limiter.

    Yeah, that's what Jerry said....I think he wants to try that for the time being, before I go reflash

    Thumbs up None of the above

    I had the same poping noise on mine before I went RIVA STAGE III, I was far from the limiter, It was running extremely lean on top end therefore poping...Take care, Julio...
