    Alright GPR guys let me know what you think?

    im finally starting to put my 1300 back to together. you guys can let me know what you think about what im doing and help out if you have any extra ideas. well to start off i will say that my dad use to have a jetski shop and built three time world champion Charlie Williamson's jetski. so he has been doing all of the internal work.
    ok now the list of stuff. we are porting and blue printing the cylinders and case, putting factory tripple pipes, msd total loss ignition, taking off the efi and putting 48mm blackjack carbs, new intake grate and ride plate, 87mm pump nozzle, solas 14/22 prop, delta reeds, and a few more minor things.
    i'm hoping to get about 80-85mph. what do you guys think its gonna do?

    reinforce the pump tunnel with PPK and upgrade the ride plate,intake grate and shoe brackets while your in there as well. Just get it all out of the way.

    ps: UMI steering and a tach would not hurt

    sorry forgot to mention.
    we have already reinforced the pump tunnel and put new pump shoe and ride plate brackets. so im hoping that will do.

    i already have makini super bn 44mm carbs. so i am planning on sending them to jetworks. will novi bore out my carbs?

    Where can i find a PET TACH? and what do they normally run price whys?
    and what all do you have to do to fit the umi steering?

    Sounds like it's going to run good. PET's are available anywhere.
