Which size piston?

Im looking to order a piston for my 2011 kx250f and would like some opinions.  Im pretty sure stock is 76.96mm but on a used cylinder would it be smart to go with a slightly bigger one as in 76.97mm? I ask because this is common on 2 stroke motors just not sure as this is my first 4t.

Anyone?

Anyone?

You should get a 77mm Wiseco piston kit for $153.99 from Rocky Mountain plus a Tusk complete gasket kit for $44.99 and save the gaskets you don't use for later. Works for me every time.

Plus free shipping!

That would work but Im use Pro x and Vertex exclusively.  Never been a fan of forged pistons.  Thanks though.

No problem.
