    Nice ride. I'm curious as to why you gave up on your 2007 "87+ mph" C-kit RXP?

    Is this the Rotax ECU for the X skis? If so I didn't think the Riva valvetrain upgrade was enough to run it safely? I thought more valve work needed to be done?

    If it was my ski i would be running the lightweight valves along with the Riva valve train upgrade. However, i have heard of people running 9000 RPM's with stock valves and just a Riva valve train upgrade. Better to be safe than sorry though.

    Couldn't agree more. Especially with the $$$ some of us have invested in these in the first place. Downtime sucks!

    Wow, very impressive setup, please get back to us with some results. I think your the only person with such a highly modified X ski.

    yeah, i was gonna do without the light valves, but everyone said it was risky... hard to believe it makes a difference... and F**K!!!! they arent cheap!!!!!

    My new RXP-X After the test!

    Hello Everyone!!
    This was a day that I was anxious for after I invested a lot of money.
    Please don't tell my wife !!
    Ok my 1st speed with the stock prop (I didn't put the 15/22R) My ski gave me 8400 RPM's 14 LB of Boost (that was what my gage said)
    My ski did not go over 73 miles per hour believe it or not .
    It felt very restricted but it went very very quick to 8400 RPM's and very very very quick to 73 miles.
    I'm very dissapointed I thought I was gonna go faster than that, but I read something in greenhulk that a filter that restricted the ski, after that I decided to remove it and it's pain in the ass but is something that can be done. Thank you everyone for your support and I will keep you guys posted specially Juan Delgado for letting me know all the updates of my ski. I am posting my pictures
