    Dumb question...

    Hi there. I have a 1995 Polaris SLT 750 with a newly formed hole in the #1 piston. I have been reading several things about fuel system upgrades to prevent this in the future, could someone possibly tell me or direct me to a thread that explains this in further detail? I looked but all I can find is bits and pieces. Thanks for your help.

    WELCOME to the Green Hulk Forums!!
    In a nut shell.
    Replace ALL the fuel lines, including those in the tank if applicable.
    Replace the fuel selector switch (they love to leak)
    Replace the fuel pump (I prefer the triple outlet, some the high volume as in the SLX and some the stock unit).
    Go through the carbs as the filters, jets etc. plug
    Make sure the fuel is fresh and no water is in the fuel system.
    If you need any directions etc. just ask or of course go through the tech section and check out Fuel Fuji.
    The hole is usually fron a lean running condition due to a restricted line or an air leak.

    i installed a more liter per hour fuel pump to my slt750. there are other ways also to prevent that lean #1 piston. i installed a bigger capacity fuel pump on mine because for me it was the simplest way to go. there are other correct ways too. i also take apart and clean out each carburetor yearly. replace inline fuel pump yearly. i make sure that there is more than enough fuel for all carbs. also the stock location of the fuel pump of the slt750 has been upgraded/changed. it should be installed/placed low to the hull as possible. look at my pic. also the pulse line to the fuel pump should be no more than 12" long or as short as possible. also i check/replace the one way air check valve at the fuel tank vent line yearly for proper operation. clogged check valve will lean out all carbs.

    i said previously that i replace the inline fuel pump yearly. thats incorrect. i replace the inline fuel filter yearly.

    Thank you very much for all that. It is most helpful. It's nice to be on a web forum with helpful people. I'm used to the automotive forums where everyone is a cocky prick. Thanks for all your help guys!

    Just one last question, where is the best place online to find the parts I need?

    Thanks again guys!
