    World's Fastest 1300cc GP1200R

    I made this video the day before the customer picked up his ski. I think this is probably the fastest GPR built for a customer that wasn't owned
    by the builder. It has a true stock 04 1300R cylinders that are ported
    by me. It uses stock oem pistons. The setup uses a stock Riva 1300 head. It also uses a small 14/22 Dynafly prop and a Jim's FF plate to my specs. The boat uses one of my special modified pump shoe's to stop the overstuffing of the pump. There no holes drilled for relief. And there are no jet works valves or anything else to relieve pump pressure. As you can see this setup can run at a ride plate angle of 1.2 with no trim tabs and has no worry of any type of buck or overstuffing the pump, even while doing a superman run. The hull is bone stock. My setups will handle and perform like no other. The video was shot last week, the temps were 89 degrees and around 84 % humidity due to a rain shower before the runs. The ski will easily run in the low 90's with a larger prop and better weather. The motor was built in
    mild form, detuned for a long lasting setup and hard riding. The customer
    also picked up his single pipe 1390 boat. It went also 82 mph with just
    stock oem reeds and stock modified carbs.
    The story here is, some have given up, some can longer keep up, but I have just begun.
    Before you party out your GPR and install a RXP motor and spend thousands of thousands of dollars just to break into the low to mid 80's,
    take a look in how fast you can go with a simple Oem 1300cc motor.

    The two video below shows the customers 1300cc, the first run was slowed by a patch of grass geting stuck in the intake grate. The second
    run was on a full heat soaked motor with the speed still climbing at the end of the run.

    Must have some really nice carbs to go along with those pipes. But seriously, 1300CC and 90+ mph ski. Ben you rock. You should be getting my cylinders for the BB today.

    Ah, okay thats what I thought.

    Leo has a triple piper 1300cc running about those same numbers set up for acceleration. I don't even think he is running a Jims plate. He is also running a 1200 grate.

    Nope, Just showing people there's another way to get there. Who they pick as a tunner is left up to them.
    By the way, your old 1300 oem motor you sold I have in my shop, it
    to will be running that fast soon. Cheers

    IMO he isn't. I would have never thought 1300cc's would do 90+ mph and still be reliable. I think he is just saying hey, look what I built, don't get rid of that 1300cc motor just yet to get a RXP motor or other 4 stroke, I can make it go 90. Nothing wrong with that.

    Either way, everyone agrees both setups (RXPGPRs and 90+ MPH GPRS) are bad ass.



    Anyways back on topic. What is the fastest Single Pipe 1390 setup you have done so far???

    I wouldn't consider a triple piped anything to be reliable unless you only do top speed runs on butter smooth water.
