1 Cylinder Proof of Concept

This is a one cylinder engine I designed to act as a proof of concept for a larger 12 cylinder engine I'm designing. The bore and stroke are both 60mm with a 4 valve DOHC head. There is space built in to increase or decrease bore and stroke as needed. I am currently finishing the block and about to start the head.
