Default RE: Why don't we have more 4 stroke gassers?

ORIGINAL: AJsToyz

Wondering why the piston was made with three ring grooves? I know the Saito glow four stroke only uses one ring, not sure about the gas, or the other companies. The NGH has two compression rings and an oil ring groove? Was this piston made for this engine or was the displacement made around the piston?

I'd hazard a guess...weight savings?? (TIC)
