    98 GSX Wont start in water

    I can start the ski on the trailer with water applied, it will idle without any assistance, but after about 1-2 minutes it seems to want to die. Idles around 2200RPM on trailer.
    When I put the ski in the water, it is a complete pain to start, if I do get it started it will only run for a short time. If I do get it started on the water, and give it gas somewhere around 1/4 - 1/2 throttle it wants to die.
    Any insight?
    Rave valve?

    Have you checked compression? I had similar problem on an old ski and i had low psi on one cylinder.

    You only need three things to start, compression, spark, fuel. Check them in that order (easiest to hardest)..

    compression is 130 / 132 in the cylinders. Spark is real strong.
    So I am guessing next would be fuel.
    I cleaned the 2 part filter in the front of the ski, that had some junk in there not sure what it was. I am still running the grey fuel lines but they seem to be in OK condition.

    RAVEs have nothing to do with idle. Fuel delivery is more likely.

    I thought I read somewhere that if the rave's where out of adjustment that they could cause the ski to die after idling.

    naw raves typically cause top end issues.

    I would guess since you still have the gray lines that your carb filters are clogged. I have seen them real bad from the lines breaking down. Also your carbs prob need a full cleaning.

    When was the last time the ski performed correctly?

    You can take the springs out and let the RAVEs open all the way up and run around all day. Off idle and mids will be sluggish, but it will start and idle all normal like.

    All the RAVE does is change the postition of the top of the exhaust port.

    well to be honest with you I don't know when the last time this ski ran correctly. I got the thing non running, due to bad MPEM. Got it up and running finally and idling on the trailer. I have not tore into the carbs, but now after letting it run on the trailer I looked at the plugs and it is running extremely rich. I will be tearing into the carbs tonight to look through them and see how bad they are.


    Thanks all..

    Take a screwdriver, 1/8" blade, and stick it into the 5/16" line that connects to the carbs. Twist it inside and attempt to scrape the walls. When you pull it out, it will have a sticky brown/green residue on the blade. This is what happens, the insides delaminate and clog the small internal filter screens inside the carbs. Read the Fuel System thread up top and do all they instruct to do.

    If you take the carbs off just put new lines on while you are at it. It will take an extra hour tops. You can get lines at NAPA for about $1 a foot.

    I would expect a lean condition if the carbs had problems. Why would you be that rich unless someone played with the carbs jets or screws? Maybe you are so rich you are fouling out the plugs and that is causing it to die.

    What about bad gas? How old is it? Stabilizer added?

    I would still put my money on a carb cleaning...(my 0.02)
