Hi Everybody!
Here is a creepy illustration of mine showing the measurements I need(marked with red question marks), to manufacture my piston for DKW NZ 250 (I have a factory IZH base-measured piston, that one should be "optimised" with brand new parts/custom rings etc./, the bore of the cylinder is big enough, 'cause it is well used;-)
The picture is only for illustration purposes!!!
