I have the KB 96mm pistons and cast cylinders from EMW, The piston have no info in the box, but I have read the min wall clearance is .002 does that sound right. ? seems to be a little close for an air-cooled engine.

Did you get the set directly from EMW?

Mine had documentation in the box.
I could scan it for you when I get home.

Yep P/C and rods all from EMW

I'll look through the boxes again but I didn't see anything the first time, Just the pin locks in with the pistons.

Call EMW, they will tell you over the phone...cool guys there.
