    70+mph on '06 GP1300r?

    Just wanting to get a consistent 70,71,72... out of the ski. Wanted to ask the experts for advice. What do you guys recommend? I have PPK, Riva grate, and unmodded R&D plate on it now. It has hit 67 but that was great water and all. Looking for an everyday 70mph ski. Any help would be great. Thanks.

    Send that ride plate to Jim's Performance it will get you some instant results. also make sure you have clearly defined steps on all parts underneath any edge that grabs water will slow you down you want what I call the shingle effect.

    What else am I going to need to compliment the 14/20? I have read in the past that you couldn't just slap on a dynafly and get the full advantage without other parts. Thanks.

    my first bolt-on was the dynafly and hit 69. others have had trouble getting the rpms for it. either way, you will need the dynafly. now or later. sorry first thing was stock riva plate and intake grate and THEN THE DYNAFLY

    With stock engine and 14-20df, 87mm nozzle is a must. If u use the stock 85mm nozzle your top speed will be literally the same, but its a sick lame duck on accelleration. HUGE difference. You can buy an 87 exit nozzle or bore the 85 to 87 as i did. Any machine shop should be able to cut it for you.

    When you say HUGE difference, are you referring to the 85 over the 87? If I were to get the EFI,d-plate,modded ride plate, and dynafly then would I still need the 87 or would I be fine with the 85? And any ideas what this combo would do for me? Thanks.

    Yes, you need the 87 with the 14-20 period. Ive ran mine both ways, no comparison. double the feel of accelleration with an 87 nozzle and still have the same top speed..
