    Waverunner FZR (Stage 3) very loud vibrations at fullthrottle

    I have a Model 2009 FZR.
    A friend of mine got the same
    Last week we modified it with those Riva and R&D stage 3 stuff

    Now only i got those very loud vibrations at fullthrottle, (8100 RPMs) my friend not.

    We both got the Riva Waterbox, but no freeflow Exhaust kit.

    I think this vibrations come from the waterbox or the origin plastic exhaust ???
    Itīs kidding me. If i stay at fullthrottle after3-5 secons the noise disappear again

    Has anybody a idea?

    Hello,

    i am very positively supprised about the quick response on this forum (i am a newbie)

    Here is my Hardware:
    FZR 2009
    R&D intake Grate
    R&D powercore insert
    Riva air intake
    Riva e1 Wheel
    Riva Wheelshaft
    R&D power intercooler
    HKS-Blow off
    Riva Breather upgrade Kit
    R&D 525 Injectors
    SkatTrack Impeller 13/25
    TBM anti cavitation cone
    Rivapreassure Regulator
    R&D ECU reprogramming R3
    Riva Cooling upgrade Kit
    Riva Waterbox !
    Like i told before: My college has the same stuff onboard but no vibs

    But we got no freeflow exhaust kit.
    What we did is remove the extra souddampner and blanked it off with a selfmade plastic corc (PP or PET or something)
    I think i try the freeflow exhaust next, because al those plastic exhaust crap is trending to vibrtions
    Please look at the video on youtube
    I did a holeshot. The vibrition are comming soon, but if i loose the thottle for 0,5 seconds it disappear and i can go on fullthrottle again without those vibs.

    You need to provide us with more info. A parts list of ALL your mods will be helpful. It sounds to me you could be experiencing MASIVE cavitation (prop spin) on take offs, Julio...

    Big vibration can be a bend prop.

    Current interpretation would be that the impeller is not the issue as it is new from the kit (assuming it was correct), you feel/hear this when you nail it from a stop and then it stops (or significantly reduces) once you get moving and that would be cavitation.

    The vibration that I got from the stage 3 and alot of other members was from the E1 wheel, but it wasn't loud in any way.
    And another thing I noticed is with the stock intercooler where the BOV was mounted apparently since it wasn't a sturdy mount the BOV was able to vibrate freely when letting of boost but when I installed the powercooler and put the BOV on a sturdy mount when the BOV was letting off boost it vibrated the whole ski. IDK if this could be you problem.

    Hi
    Vibration only on fullthrottle at about 8050 or 8080.
    After 4 secons of fullthrottle the noice disappears.

    If you got good speakers on your computer, watch the video on youtube so you will hear the problem.

    Today the problem does not appear........crazy problem !
