    98 SXI Pro for Racing

    Hello,

    I'm going to be picking up an '89 SXI Pro sometime next week and I was wondering if the SXI Pro's are good racing skis. I'm not gonna be running the pro classes or anything, but for the average novice rider would it be a good, stable, and fast-ish racing ski?

    I was wondering what the top speed for an SXI Pro would be.
    All It has done to it is a pipe, impeller, and filters.

    Also, what should the compression be and what should I look for when I go and check it out in person. I don't know too much about jet skis so give me some tips of what I should look for before I buy.

    I raced an 02 pro for a few years. It was fine for me since I race a few local races per season and rec ride the
    rest of the time. However, I did notice that you do have to work a bit harder to get around the track than the SJ's and especially SXRs. Compression on a healthy stock sxi pro is around 150psi in each hole. Oh, and adding front tubbies, rear hull extensions and 0 degree bars helped it handle much better around the bouys..

    fine racing ski and will blow a sj out of the water and be really close to a sxr800.stock for stock they ran just as fast or perhaps a bit faster than a sxr.hull bottom has a lot of similarities with sxr.
    front sponsons and hull extensions will do wonders.get rid of factory rear plastic sponsons
    hope it has the dry pipe with ecwi.

    I plan on putting ProWatecraft front, rear sponsons and ride plate on. As well as I am thinking of getting RRP pole and straight bars. If I can find an aftermarket pipe I will do that as well.
    So overall it is a decent race ski for an average guy like me? Cool thanks for the tips man!

    It does not, only stock pipe but I will try and find an aftermarket pipe.

    Re: 98 SXI Pro for Racing

    Check out my thread in the individual builds section. Basically you can get to 80% or greater the sxr performance at 50% the price. And actually, I know what future mods I could do to my hull to make it even better. The key things the pro needs are front sponsons or tubbies, and rear hull extensions. Secondarily, an aggressive intake grate and ride plate. One of the huge benefits of the pro is that it accepts sxr ride plates, which means you have a whole bunch of options on what to run.

    When Kawasaki created the sxr from the pro, they basically increased the front hull surface area, set back the pump, and made the ski heavier. Not sure if the weight was done on purpose or not, but it really helps plant the ski. Aggressive tail end stuff on the pro does the same thing as adding weight to the front. A super aggressive intake pulls the ski down even more. With all the mods done to my hull, it was slammed to the water. Would not porpoise at all.

    I would definitely take my pro over a 2 cyl sxr. They feel smaller and lighter and more nimble, and when properly set up can rail just as hard. My ski with a tbm sxr ride plate felt more locked into turns than my brother's stock hull, stock ride plate limited 1100 sxr.

    Re: 98 SXI Pro for Racing

    Oh and regarding the comparison to the SJ, I personally feel based on my time on a variety of these skis it would pretty easily beat a 90-07 SJs around a buoy course unless they are extremely modified and ridden by a very experienced rider. I know some racers back in the day went way faster on SJs than sxi pros which were out at the time, and it really blows my mind to think of that. I really would like to know if they all raced the skis flat or if they modded them to carve better.

    The 08+ is a different story. It's basically like a further evolution of the pro.
