Dale designed his high compression piston kit to drop right into the original 79mm bore cylinder, and JE is known for making some of the highest quality pistons on the planet today. All that is needed is a light flex type hone to freshen up the cross hatch and back together you go.

This kit will make your B-12 a real screamer
