Let me introduce to you the 2003 Rasant Twin 2 x 0.098 cam Mk I diesel engine. The engine crank case was machined from bar stock and sand blasted. We manufactured 30 of these engines. The cylinders and spinner were anodized in blue. All of these engines have 2 intake and 2 exhaust ports. This engine has a one piece crank shaft and divided connecting rods. The connecting rods are held with two miniature screws.
