    96 XP Rec Build

    After being out of jet skis for several years I got the itch agian.
    Back in the day I used to ride blasters and race a limited class GP1200R. I wanted to pick up somthing cheap, small, and fun. Another blaster would be my first choice but I've gained a little weight since then and thought somthing a bit bigger that I could still jump would be better. I rembembers seeing alot of little X4's at the races so after having numerous Yamaha and Kawasaki jet skis I have finally gone to the dark side and picked up this little gem for $800 with the trailer.

    The ski did not run when I picked it up but the owner assured me that it would with a new battery and DESS button.IMG_0916.JPGIMG_0915.JPG

    Re: 96 XP Rec Build

    My plan was to get the ski running well before doing any engine modifications but the ski had other ideas.

    The first changes I made were the seat and steering. I stumbled across someone nearby that was willing to trade my stock seat and $50 for a 95 XP800 hump seat. I like the look of the 95 seat better so I went for it. My next modification was to put on some UMI bars and a KVPI throttle on, I cant stand the thumb throttle and seadoo sideways steeringIMG_0979.JPG

    Next up is the exhaust. Like I mentioned above the ski had other ideas regarding remaining stock until I got it running good.
    Up to this point I have only taken it to the lake twice. Both times the rides lasted less than 10 minutes due to water in the hull.
    The first time I thought the water was coming from a few screw holes in the transom from a bording step that I removed but forgot to plug the holes. After a quick repair I was back on the lake this time for a bit longer but there was still alot of water in the hull. After getting the ski home and running it on the hose this is what i found.

    Luckly one of my neighbors has been parting out seadoos for several years and had a Factory Pipe Spec 1 he wanted to get rid of so I bought it. Now the fun begins

    Recreation / Match porting
    I ported the cylinders today. I have a spare set so I decided what the hell... Ive done other port work before but these are the first cylinders I have done. Just like all factory cylinders the sleeves are not perfectly alligned with the cast cylinder ports. Both sleeves hung down into the ports about 1mm and were clocked about the same amount. I didnt want to do anything radical just matched the ports to the cylinder sleeves while keeping the entry angles the same. Should be interesting to see how she runs.

    Re: 96 XP Rec Build

    Did you cut out the taper on the exhaust ports that lead to the
    rave valves?

    I see now, a little bit. Did you have the rave valves installed when
    you trimmed the exhaust trac?

    I recommend you pull the pump, disassemble it and verify that it has
    whatever impeller FPP recommended. At the time that pipe was built,
    it was common to spend a few months on the pipe R&D, and in the end,
    most pipes produced only a few extra HP, and could not pull a larger
    impeller.

    The days of finding easy HP left on the table by the oem manufactures
    was gone!

    The work I did on the exhaust tapers off as it goes up to the valve. I didnt want to mess with the top of the exhaust port or the valve because I wasnt sure what to do with it.
    The exhaust picture is upside down

    Leave it alone, it saves a lot of low end and mid-range acceleration,
    while providing nearly 200' exh duration. You're stock engine has race
    cylinder porting, and the rotary valve provides power that reed engines
    wish they could provide.

    You could easily cut 10% of the peak HP out of the engine by raising
    that area.

    IMO, your engine only needs to be a good "limited," combined with some
    pro tuning, will provide great results.

    Just to be sure, I recommend to install the rave valves and make certain
    the leading edge of the valve doesn't create a sharp edge hanging down
    into the exhaust port.
