But what about the rings? How will I make the rings once I've modified my CG125 engine to take the new piston and valves...?

[Ian]

I think the stroke might be a little on the long side for a CG 125 ?
You'd might do better with a MZ250 or C90

And it would be very low compression with that cut out in the top ,Make a good party size ash tray though..
As for the rings ask the seller ,I bet he'd sell you some .

I just liked the size of it !
