    1990 Square Nose SuperJet Build

    I Recently purchased my first Stand up jetski. I am coming from riding kawasaki 550sx's at a friends lake house and every summer for the past 4 years I've said I'll buy one of my own. Finally found one in decent shape, one owner, and unmolested for a decent price.

    Say hello to my 1990 Square Nose Superjet 650.









    It came with a couple aftermarket parts/accessories:
    1. Extended length R&D Ride
    2. West Coast Intake Grate
    3. Electric Bilge Setup
    4. Primer Kit Installed

    Decided to replace the what seemed like original Turf and i wasnt too fond of the very dated decals... so I started tearing it apart...

    Parts Ordered:
    1. Worx 201 Intake Grate
    2. Yellow Camo Hydro Turf Kit
    3. Jet Works -4 degree bars(black)
    4. Odi Grip set
    5. Blowsion Finger Throttle(black)
    6. Billet Bilge Fitting(black)
    7. Billet Boy Eye bushings(black)
    8. HT Shock Pad
    9. Blowsion Freestyle Pump Cone
    10. Protec Steering Nozzle(+20mm)
    11. Blowsion Single Bilge Mount
    12. AC Racing -2" Aluminum Handle Pole(white)
    13. Decal Kit (Ebay)
    14. Stiffie Registration Numbers

    Had the Stock Chin Pad Recovered in Black and test fit on AC Handle Pole




    Removed Old HydroTurf and Decals.




    New HydroTurf Installed.






    Majority of Decals installed... The Yellow in the decals for the bottom of hull doesnt not match the yellow in the turf or reg stickers so i wont be using them.. contemplating just making black decals for the bottom.








    Ac handle pole, Handle bars and goodies installed. There are decals going on handle pole as well that matches rest of decals. Luckily I did opt for the aluminum pole because upon removal of stock handle pole I found a couple cracks and the handle pole was literally filled with water!






    Installed Intake Grate, Steering Nozzle, Pump cone and all other goodies...





    Had a couple issues on Maiden voyage.... One primer hose was leaking causing air in system and for engine to die out whenever it wanted. Had to Rebuild Carb and Freshened up fuel pick up. I should have known considering it hasn't been ridden in 1.5 years.

    Contemplating a different ride plate maybe a D cut style. As you can tell I havent done too many mods to the engine and that's because I don't want to waste money if/when I do swap this for a 701(61x). but for now I will rock the 650 considering it is night and day improvement than a 550sx.

    Also having a newer style "superjet" logo made to match the other yellow on the ski. And contemplating making replica warning labels in black/yellow for the hood.

    (Superjet logo here(on both sides and on handle pole)




    (sizing up for new warning labels)





    Let me know what you guys think and if you have any opinion on anything else i should change for the better!

    Why did you buy an MSD coil? Forget all that crap, look for a 701 shortblock to swap in instead of that 650. Best mod you can do. Nice ski, though.

    701? If not get a 61x cyl on there or a whole 61x. Just built my first sj this season, 1990.
    I have a cheap wetjet pipe that will wake that thing up, 180$.

    61x is a 701... 61x is single carb, 62t is dual carb .. iirc.. please correct me if I'm wrong...

    Pm me info on the pipe you have? Wasn't really looking g for one considering didn't wanna go through the hassle of rejetting the carb but let me know...

    MSD coil is doing nothing but sacrificing reliability. and it's wishful thinking to believe you'll gain anything but a marginal performance gain with an MSD cdi. Those two things alone have to be, what, $400? A nice 61x/61x short block is like $500..... if you don't want to spend the money, stick with a 61x motor. Intake is basically free, and you can use the single 44 carb on your current motor.

    Take off the exhaust on your 650 once and examine the ports on the cylinder and compare them to a 701. It's fairly apparent why no one wants 650s...

    A 650 with a b pipe (the most expensive pipe) will still not have the torque of a bone stock 701. B pipe on a 701 feels like a rocket ship in comparison.
