    Riva Waterbox and Freeflow Problems

    So many people got the Riva Waterbox and the Freeflow Exhaust kit on their skies.
    But it is not possible with my configuration, because I got this kidding noisy rattle at fullthrottle.
    It seams that my air/fuel ratio is to lean. But when we increase the fuelpreassure the ski would not run correctly anymore because itīs getting to fat!
    Could it be the knocksensor, that is coming on those waterbox vibration ???

    Get an afr guage!
    I doubt your problem is coming from that combo.

    @Green Hulk: AFR Gauge. Do you think the ski runs to lean at the upper rps 8000. And the rattle are detonations ?

    I had that problem due to running a gutted stock water box at 14LBS boost on stock injectors. Ordered the 1000CC Riva injectors from the online store and my problem went away, Julio...

    Looks like it got real hot. You need to check your AFR before you have pistons that look the same.

    an AFR gauge will tell you if you are going lean or not....
