Could be .010 over. Maybe.

But often when having custom pistons made the clearance is machined on the piston. So you bore/hone the cylinder to .020 over, which is 3.2075. If the desired clearance is .0075 the piston skirt gets cut to 3.200.

So there's some speculation here, we don't know for sure if the 3.200 size listed is perfectly accurate, so who knows for sure?

But as long as we're pickin this apart the brand listed shouldn't be Kawasaki.
