    Need Help!!

    Sorry guys for asking this question... i am probably sure that you guys answered those kind of question.

    i am a biggner in jetski's and i just bought a gpr1200 model 2003 and the engine have never been touched.

    i am planning to rebuild the engine.. while rebuilding i want to tune my ski for maximum power and top speed

    what i'll change is trued and welded crankshaft, seals, pistons, rebuild carb. kit. and planning to remove the waterbox and replace it with a pipe.

    is there anything else i can add and tune for topspeed?

    if u recommend a cdi guys which one do u prefer?

    2003 if Fuel Injection, 1300. Why are you rebuilding if the motor has never been touched? maybe I don't understand.

    Welcome to the forum, search around, there is too much good info on here to not use the search.

    If it is a 1200cc it is not a 2003. The 2003 is a 1300 fuel injected model. Please let us know which one you have.

    Use the search function and you will have enough material to read for a LONG while. Many good suggestions all over the forum.

    What they said.
    Knowing which one it is for sure will help with suggestions.
    With either one though I would not remove the waterbox. Sound supresion maybe (depending on which one it is).

    Tell us about the type of water conditions that you will be riding in. Some set ups are for smooth water, and others are for rough water.

    Will you be riding two?
    Will you be racing?

    The more you tell us the better we can help you to set up for what you need.
