from 1968 to 1980. The engines were air-cooled, three-cylinder, piston-controlled inlet port two-strokes with two exhaust pipes exiting on the right side...

A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine. The main functions...

horizontal, single cylinder, water-cooled, two-stroke engine that uses piston port injection. It has an inner diameter x stroke = 39.0x41.4 (mm), with a...

Because the exhaust port was located near the lower pistons, the engines suffered excessive lower-piston temperatures which led to piston failure, which could...

directly out of the exhaust port prior to the piston rising far enough to close the port, early engines used a high domed piston to slow down the flow of...
