    modified rxp jumps to much. how to correct???

    i took my 2005 rxp out for a spin today and it was jumping all over the place. does anyone know how to correct this. my sky was just totally modified and should be somewhere around 325HP + or _. i have a 16 vein pump from rotax racing and the engine is a big bore with 104mm forged pistons. oversized incanil valves on ported and polished head , race cam and a RUDD supercharger.Thank you Bryan, the sky runs great, but i need to find a way to keep it in the water. can anyone give some suggestions on what to do.
    ps. i have an extended plate already

    Two items that I don't see in you post that you could try are the RE OPAS block offs, these will extent the hull slightly and decrease proposing and an intake grate, especially a toploader like a Riva grate.

    Lean forward when jumping a start...but for porposing the RE Blockoffs are the thing!

    i left those out of the list , but they are both on my sky already from riva . the extenders and the riva intake grate. any other suggestions. after the ocean today, i took my sky to a flat lake , and when it is in the water, it flies.

    the sky is doing 8550 rpm with an 85mm nozzell ,the torque is insane, but how do i keep it in the water. did not GPS jet but i am guessing mid 80 mph

    Are you talking about porposing? or jumping out of the water at WOT start?

    how does a pump wedge removal make a difference, please explain

    "If" you do not have a VTS extension rod and have the wedge on you will get less downforce on the RXP. Taking the wedge out might help with this issue by keeping the front down pending on your riding style. Personally, I like the wedge with the extension rod! I gives you more movement for hole shot and more playfullness for wave jumping!
