    I did it the way I've always checked plugs on motors.... WOT 15-30 seconds and kill the motor, although this is the first time I did it on a ski. I did it twice with two different sets of plugs with...

    I agree, but I do think it's a little lean... maybe more than I'm comfortable with. Maybe I'll just put the sc back to stock till I get an AFR gauge on it this winter as I already lost one ski...

    What do you think of this plug condition?

    What's your opinion on these spark plugs coloring/ condition? The first and third pics are one plug the second and fourth are another.

    Actually I was told that either of those would work in my application.

    I checked both ways, and on my ski there was no difference. Key on post, or engine running without boost line attached...

    RRFPR question?

    Guys, if you are supposed to set a ski up with 58lb base pressure with rising rate,

    is the 58lb with or without the boost line for the rrfpr . Because if you set it without the boost line and...

    So I spoke with a reputable source today and he tells me a way to run a 137 wheel on an '08 T-X is to use the stock 42lb injectors with a RRFPR set to 58 idle with rising rate. He says this is a...

    I modified the stock grate by removing the outer wings of the water deflection area. I left the center for some top loading of the impeller. I picked up about 1 mph and I was heavier and near the...

  12. 2008 RXT-X 255 ( 137 wheel ) RRFPR settings?

    Fellas, I'm adding a 137 wheel and 48lb injectors along with a R&D RRFPR that I bought from Jerry.

    I know this can be run like this very safely on a stock tune, but I don't know what to set...

    I would check the wear ring first as .040 gap is your service tolerance between the ring and the center of each impeller blade. But tighter is definitely better.

    Also look for damage to the...

    That's what I'm hoping for. It doesn't do it on the trailer, only on the water, so it makes it harder to find a source

    Hmm... no one else with this experience? That makes me lien towards the idea that it isn't normal for the RXPX RXTX 2008-2009.

    It's kinda scary to think that Riva sells tunes that border on dangerous. Thanks for the advice, maybe I'll go a different route and switch to the 137 wheel, 50lb injectors, and RRFPR that PWC...
  20. 2008 RXTX small vibration only at idle... maybe normal?

    So I have a recently acquired RXTX 2008. At idle only it has a vibration or roughness that is enough to shake the handle bars, and you can see a little vibration in the mirrors. Sometimes it seems...

    Thanks,

    I switched nozzles/venturi and threw on a 3" air intake I had for my RXP and picked up about 1.5 MPH getting it to 69.4 but my rpm's are 8180 so time to tweak the prop. I didn't...

    Yes, they are the 42's. According to Riva, they work with the tune for 8350. Do you agree?
  25. RXP nozzle/venturi swap to a 2008 RXTX PROBLEM

    Guys,

    I'm looking to try my smaller RXP nozzle/venturi on my 2008 RXTX, but the RXTX has a small hose connected to it that I believe is the SC discharge.

    Will it work to just remove the hose...
