    sounds like you have money to burn (my opinion don't just throw money at the ski do the research for the mods. that truelly do make the ski more suitable to your requirements) what exactly are you looking for? or wanting from the ski?

    yeah. You really should research more. Sponsons wont get you more HP.

    What is your goal?

    I wouldnt start with those mods personally. Sponsons are expensive..With little gain UNLESS your racing CC. (Just my .02)

    Best mod for the buck! Modded timing wheel. Do a search.


    BTW.. DO NOT BUY THE RIVA PRO FILTER! DO NOT BUY THE RIVA PRO FILTER!

    I say the RIVA pro filter. I recall COPPERHEAD sucked in water. It was because of the PRO filter. This is the one that utilized your gloovebox. I'm not sure what their other filter is called. For all I know, Riva coulda pulled it from the shelf. Their other filter seemed to be a good quality build. I got me a 4" Kanoflex, with the R-Rated TROBONE at the end. Works fine...Except for that 1 time!

    From my recollection the pro is the one you dont want due to possible water intrusion. The performance is the glove box one. I could be wrong though. As it has been said, the timing wheel is by far the best for the money (I'm getting mine done tomorrow). Perhaps a ride plate will get you some speed as well, but which one to get depends on the conditions that you will be riding in. I am getting the R&D plate tomorrow as well. (Thanks to Dubz for the awesome connection! )

    Blu, from what people say, the stock air box is very unrestricive with no chance of water intrusion.

    ..but if i am correct...little or no gain in top end or HP.....

    for the first mod i'd save that 250 bucks and put it to a ride plate or Impros mod to your pump/impeller with those two ALONG with the timing will give you the most performance gain for the buck............

    A Ride Plate/ Pro Filter/Riva Water Box and modding the timming wheel will give you 3-4 MPH and more accel.
    I have a great price on these parts for an 08 if you are interested.
