The engine was | The engine was an [[air cooled]] dual cylinders, four-stroke. A 50.0mm [[bore]] x 41.0mm [[stroke]] resulting in a [[displacement]] of just 162.7 cubic centimeters. Fuel was supplied via twin carbs and shared a common choke control. Two valves per cylinder operated by overhead camshaft (ohc) with tappets accessible through screw on covers to front of cylinder head, and points and condenser(Capacitor) under a cover at one end of the camshaft.. Ignition by one coil with a +ve lead to one plug and -ve to the other, circuit was completed via engine block and both plugs fired together. (Lost spark system). At firing, one cylinder was approaching TDC on the compression stroke, while the other was approaching TDC at the end of its exhause stroke. Both pistons moved in unison.
