    slt750 goes then dies down over and over

    took my ski out yesterday it would go good for a little while then die down like it was going to die.sometime it would die sometime it wouldn't. i had to replace the lines in the tank last year and noticed the gasket under the cap was falling apart.would that be considered an air leak.........thanks for all your help guys

    The gasket under the fuel tank fitting needs to be air and gasoline tight. Just for safety, to prevent fuel fumes from accumulating inside the hull.

    Have you made any changes since the last time it ran properly?

    Did you replace all the fuel lines?
    Fuel restrictor installed in replacement return fuel line?

    Did you install a new triple outlet fuel pump?

    Have the carburetors been removed and internally cleaned?

    Do you have water inside the fuel tank?

    A leaking fuel cap can allow water in. Also check the gas cap itself, and the filler neck for cracks.

    If you have a fuel/water separator, check for water. The float ring inside (if it has one) should be sitting on the bottom, not floating on water.

    If your fuel sender gasket is rotting away, pieces may be inside the tank and now your fuel filters.

    Replace the gasket, inspect/replace the in line filters, check the water seperator, check the petcock for restriction, check the filters inside the carbs.

    Do a compression test. You may have been seizing a piston.

    Were you getting a HOT signal on the MFD?

    hey guys
    was able to get my carbs off and get them cleaned.i need to know why my diaphrams were sticking to the back covers of the carbs. each diaphram was stuck like that..ordered some new needles and seats as they looked bad. i think that may have been my bogging problem

    thanks again guys for any info you can give me

    They often do stick to the outer cover. As long as the middle portion moves in and out allowing the needle to come off the seat, that's ok.

    Be sure to inspect the diaphragm for defects.

    Just tonight I was about to re-install 3 diaphragms when I held them up to the light....

    Needless to say 2 were junk and 1 was fine.

    Pin holes all around the edges of 1. Just looked worn through.

    The other had a small tear.
