    WTB useable 750 STD bore piston

    I know..crazy right..
    but I have a complete 93 std bore 750 that needs 1 piston.
    I just want to find one useable one to put this engine back together and keep it as a spare or for a future project.
    Anyone help me out?
    Also if anyone needs a blue very descent SL seat for the price of shipping let me know.
    I also have a complete 93 pump I would let go cheap along with a complete unmolested wiring harness and ebox with all gauges including trim from the 93 SL 750.

    What single piston kit? The cast bore is good and I know lots of parted out skis had to have useable piston left around...I have hardly nothing in this complete 750 engine and not going to spend $100 just to store it on a shelf.. The cheapest complete kit I see is like $270. Maybe next year I will do a complete rebuild from bottom to top but for now I am pinching pennies.
    Thanks though.

    I actually think I have one for some reason. Brand new....but will need a ring set with it. I'll double check the part number if I can find it in the shop.

    If he has 1, you can get a WSM ring set that will work for $20 a set.


    Here's a single piston kit.

    Here's a used piston/cyl combo

    Or have your cyl bored for a .25mm oversize and get these

    That would be great. I have a good set of STD rings.....and a upper rod bearing and pin... I am uncertain if I have the correct circlips...but that is a non issue if I could find one good STD piston.
    I see several STD and 10-20 over bores....but they never have rings with the. Do WSM rings fit Polaris pistons? Are WSM manufactured in China or Taiwan?

    Looks like the one I have is for a 780.....at least that's what I'm assuming by the "78A" printed on top of it.

    Yes WSM will fit OEM pistons

    Not sure on where made, but they are quality parts that most of us use.

    78A would be for a 780.

    Man I thought for sure someone that parted out a 750 would have one good useable STD bore piston for a good price.
