(...) Oh ya, no doubt. I think one of the reasons for this whacky two piston, one cylinder, central combustion chamber arrangement is that in an exhaust port system, with the proper amount of lag between cylinders, you can arrange the exhaust to (...) (20 years ago, 26-Jan-05, to lugnet.trains)

(...) They are probibly a lot more efficent when whey do have exhaust vales. A basic two stroke doesn't clear the cylinder of exhaust very efficiently. By opening the top of the cylinder through exhaust valves the rush of intake air will definitly (...) (20 years ago, 26-Jan-05, to lugnet.trains)
