    RXT-X upgrades ?

    hi all, i have a stock RXT-X now run in with 14 Hours on it & want to give it a faster top end without losing any acceleration (or hopefully gaining some), i live in the North East of Englend UK & ride mainly on a river with a light chop & out to sea with a big chop, i ride with a Kawasaki ultra 250 with mods & he rides the chop well where as i skip at times losing some top end,
    i have read loads of posts on what to install & have put together this list & wonder what your thoughts are on how it will perform, i am thinking of installing-
    Riva 3" Power filter
    Riva Intake Grate
    Riva 2 degree pump wedge
    Riva VTS extension rod
    Riva opas competition kit
    Solas stainless wear ring
    Riva sponsons kit

    i am not sure if i should also fit a RIVA Pro-Series Reduction Nozzle to reduce to 81mm & a solas impeller 15/21 or leave the stock impeller & have a go at tweaking it as described on this forum,

    any thoughts on these upgrades or any changes that would improve my ski would be appreciated

    cheers boys, Qatar i dont really want to mess with supercharger & intercooler yet incase i have a warranty issue in the future but may do these next year,

    so i have gone for a complete stage 1 kit + stainless wear ring & sponsons, will try & get my ski tracked on a speed gun before & after the mods to see the difference & let you know,

    Really, your best bet is to get the RIVA power filter and the JAWZ prop. This should get you 4-6mph without voiding your warranty.

    No chance unless he also gets a different intake grate.

    All you have to do there is to cut off the outer wings flush and then use a dye-grinder to sharpen the vertical blades.

    You call Mark Underwood and ask him to connect you with Jeff (JAWZ). They are buddies. Mark's number is (905) 726-3387 or (416) 806-3387.
