    Piston

    Hey guys, anyone know what a .10 means on a piston? I have that rebuild kit for a 750 for sale in the classified section and race24x was wondering what the .10 meant on his old pistons. This kit that I have for sale is a .5 overbore kit. Thanks guys

    That would mean .010 oversized. Usually it's measured in metric like your .50 is a 1/2mm or .020in. Are they Wisecos? Those are the only pistons I can think of that would use American Standard.

    The kit and pistons are WSM performance.

    Those aren't the ones marked +10 are they?

    no the +10 was on the standard pistons that race24x had. My pistons are the new ones from WSM.

    As of right now, I dont need any 780 pistons as mine are top shape (knock on wood). Why you got some?

    I thought you needed 780 pistons instead of the 750's? I may have 3 used Polaris .25 OS with NEW WSM rings hiding in the basement.
