    Fellow husky enthusiast's, motorcycle newbie in need for help.
    This week I installed a new OEM 144 husky kit (8000H2995) in my bike, it is hella-fun even before fine tuning it.
    The piston didn't come in a box, but i believe it was a 8000H1135 as it is part of a husky kit.
    My question is, when time comes, what piston will i replace it with?
    I saw the thread about the yz piston and modifying it, but i seem to have found a website that will still sell the 8000H1135, but i dont understand what sel a/b/c/d are (8000H1135/1 or /2 etc)
    What are the differences between sizes? I think my piston was sel A as it had a little A on the top as in image. (Not sure if that's what it means.
    Thanks in advance.
    Walt i concidered contacting you via email with this but thought maybe someone else in this galaxy might have the same question.

    There is about a 10th of a thousandth between each size. You can pick the one you had before. The size is often stamped on the crown of the piston. If you still have the wrappings from the piston, the part number sticker should also have the letter at the end of the part number.

    Thats the issue, it came without wrappings and i didnt really measure the piston or look for stampings but im guessing the A in the center of the piston is the marking for that (like in the pic i added)

    I have a 144 kit also. I haven't installed it yet, but wanted to be sure that I had at one extra piston for it, if I did install it. Though it came with an A piston, I ordered a B for the spare, as the difference is very small....just my reasoning that there will be a tiny bit of cylinder wear...but that's just me.

    If you don’t mind me asking , Where did you get the 144 piston or where did you see it available? I also have a WR 144 that’s probably going to be in need of a top end soon. Thanks
