Christopher Fisher (Engineering) has fitted modified Honda pistons to my 2 3/4 hp following an original piston breaking up. Would you trust 100+ year old cast iron ones?

JP Pistons in Adelaide, South Australia. Just make sure to give a couple of extra thou clearance to what JP recommends

For JP pistons about 5 or 6 thou. For cast iron pistons, much less
