    99 1200xll acceleration mods?

    Just picked up a 99 1200xl with 71hrs on it . I actualy got it for FREE! Owner couldn't get it running and it was being sold with a 03 gp1300r which my friend bought ($1250!!!!!). ANYHOoI got it running and on the water today did realy well I thought considering... Got it up to 55-56 gps on one yr old gasand seafoam. I'm ok with the top speed but would like some more bottom end anyone have any proven suggestions I could preform for under $500 ? It seems to rev up to about 6000-6500 from the bar graph tach. Any advice is thanked

    put a prop in it. best bang for the buck you can do. a ride plate and intake grate will also help. and lastly a d plate or other similar part that rids of the cat. if you want to go further into the motor a set of carbon reeds will help with some low end and still be reliable.

    What is stock prop pitch?

    not sure but best bet is call either riva or impros and ask for a prop for a stock motor. they will advise you on one that is suited for a stock motor but be an upgrade from stock. it can later be pitched up from there as modifications follow.
    previously mentioned a ride plate and intake grate will help also. thats a lot of hull in the water. you will pick up a couple mph and better hook up. you can also seal your pump, and ride shoe a couple different ways and get some more acceleration. they are sealed horibly from the factory.
