    Cool just got the 07gp 1300 W0W!

    im new to this forum and i don,t race but just got the ski i always wanted the classic black and gold new. i know there,s alot of smart jet ski guys out there so heres my question ,i want to of course upgrade for more holeshot speed and top speed and handling on my G turns riva and r,d. both have stage 1 for 1500 plus NO WAY im paying that. wouldnt aride plate intake grate solas impeller 14/20 trim tabs and pumo seal be enough? im not going to break the bank ,i rather just keep it stock. i had kawa 750 zxi that i modified and performed better (ride plate intake sponsons) i would like you guys honest insight, by the way i ride on the navesink river on the jersey shore THANKS!

    welcome to the green hulk!
    there is tons of stuff that you can do without breaking the bank
    but breaking the bank is just so much fun!
    ppk ,dplate,intake grate,ride plate, reinforce pump tunnel
    are your 1st 5 mods

    you dont have to buy a whole kit right off the bat. find used parts and peice one together over time. dont get the 14/20 prop yet. you wont have enough power to turn that thing at the right rpms.

    pretty much everything in my signature. With a stage 1 kit you would probably see better results with a 13/19 prop. A skat prop is know for holeshot. The stock prop it good till 72-74 mph. But first things to do are ppk, intake grate, rideplate, tunnel reinforcement. Also step your oem sponsons. This will give you better handling Through turns and will keep your ski from rocking side to side while riding. Everyone here on this forum will tell you to step your sponsons

    Welcome to the forum. I have an 07' gpr to and right now its being set up specifically for holeshot and rough water. My set up is going to be Skat Trak Swirl R 13/19, Leo's holeshot kit, Jet works, R&D PPK, Riva Dplate, Riva Free Flow, Riva Top loader Intake, R&D extended trim tabs, Pump Tunnel Reinforcement. The ride plate on the GPR are pretty good for rough water, but you can always start looking at plates or have one customized specifically to what your goal is. People have had 3-5 mph gains with a single plate. Thats some of the work that i'm doing to the ski but its a set up you can look at and figure out what you want to do.
