    550/650 Pump and Engine Conversion

    Iíve been working on this project for a couple years. Itís had a couple different versions and I think that this will be close to its final form.

    I bought it seven years ago as a stock 85 JS550. After some serious cutting and fiberglassing it has the guts of a 89 650sx (including the whole pump intake from the 650) with some aftermarket things. Hereís a reasonably comprehensive list:

    -650 motor
    -46 mm Mikuni (120 pilot and 150 main jets)
    -Stock Head
    -PJS exhaust
    -Dual cooled exhaust
    -Mariner water box
    -Stock 650 electronics stuffed into a 550 ebox
    -Blowsion fuel pickup
    -FCV
    -Blowsion flame arrestor
    -650sx throttle cable
    -140mm pump w/ 10/16 Impros Hooker impeller
    -Pump wedge to help with porpoising
    -Blowsion pump cone
    -PJS ride plate and intake grate
    -Rhaas products zero slop steering cable ends
    -Blowsion steering system
    -ODI Grips
    -Blowsion billet trotted
    -Rhaas bilge pump switch holder
    -Blowsion Brap Strap
    -Blowsion recessed dash switch (I relocated the On/Res switch and primer bulb)
    -Blowsion foot wells

    I did all the paint, body work, and hydroturf myself.

    Itís only been on the water a couple times and it rips. Itís worth the look on Superjet and SXR riders faces everyday of the week and twice on Sunday.

    Well done.
    Never argue with an idiot, they will drag you down to their level then beat you with experience.
