No, they don't have them anymore. The Z1 is a 40mm piston and the 39cc is 37mm and the 50cc is 39.5mm. I am modding Cag 47cc cases and cylinder to fit the one ring Z1 piston.
Have seen them in England on ebay, try a search.

I do it with my hand and sandpaper and cross hatch it. Most of the cylinders have a very thin hard surface plating. if you sand to far, well.
If you sand the walls put new rings on your piston.
