    1994 Kawasaki 750 xi ss

    Need some help with my ski.

    ((heres a little history))
    i bought the 750xi ss for 350 with trailer, he said it it need a good carburator cleaning, but he did start it for me, it revved up just fine just wouldn't idle. So I got it!! First thing I did was take it to the lake right away. It took off fast then it bogged down, so I knew something was wrong. So I took the carbs off and cleaned them, they wore really dirty, also I took the fuel filter out of the tank and it was compleatly clogged, like some kind of build up also had build up the bronze line and the top of the cap where the fuel lines all connect wore compleatly clogged. So I cleaned it all out vaccumed out the tank. Then I hooked up the hose and started good, but seems like a lot of oil coming out the exuhst??


    it starts good.
    both cylinder have 155,153.
    It is oil injected.
    Carbs cleaned.
    New fuel lines.
    new spark plug.

    So my question is: why is there a lot of oil coming out of the exhaust? What is causing this, my ski has being standing for a while.

    welcome to the GH
    is it running good
    did you check the throttle cable to the oil pump
    as you give it gas it put out more oil, it may need adjusting

    you could try posting in the Kaw 2 stroke section for more help
    this tread will probably get moved there as soon as a moderator see it
    so if you cant find this thread here, you know where to look for it

    Welcome aboard, Stranded!

    No cable to the oil pump on that model.

    It's not unusual to have excess oil flood the engine after long term storage.

    The only way to determine if it's excessive is to run the boat and measure how much oil and fuel you're using. Should be about 50:1 ratio.

    Ok I'll try to take it out on the lake today, and I'll let you know how it goes. Anybody have a aftermarket ride plate?

    As far as mods go, it all depends upon how much you want to spend on it. A head, flame arresters, with reeds, and exhaust and waterbox will really wake that thing up. I wouldnt go too high with the compression on an old motor unless you plan on doing a complete rebuild.

    Rend... A blast from the past. Their shop is about 4 miles from my house, but they haven't done any PWC stuff for years.

    What do you mean head? It's it the cylinder head or elbow head pipe? Where would be a good place to buy great parts for cheap? Or is anybody selling some aftermarket parts? Also can I just modify the grate? What would I need to do?

    thank you.

    Yes the cylinder head. ADA Racing has a billet head for I think $230. That's the cheapest one that I have seen as of lately. You could also take the stock head and have it machined. As far as the intake grate goes, I have heard of people cutting out the center grate to improve flow.

    it also might be rich or have a dribbling carb, too much fuel can wash the soot out of the exhaust appearing like oil.
    go fast,
    head
    exhaust, ill see what i have
    timing advance plate,
    tight prop,
    machine stock head,
    look at group k for some info
