That's how I feel Steve.
I just really don't understand the discrepancy between the diameters of the 2 pistons.
They only come in .25 mm sizes,
So how does one only measure half that?

Could it be a difference between forged or cast?
I thought I remember that the expansion rates are different and maybe the come in weird sizes to compensate?
