I have a 1980 Kawasaki KZ 440 A. Technically it has a 444cc motor. Is my bike a 2 stroke or a 4 stroke? I'm experienceing loss of power, believed to be as a result of a valve sticking. I had someone tell me if its a 2 stroke it doesnt have valves. There is a separate place for oil, meaning i dont mix it with the gas. How many stroke do you suppose this is? Anything at all will help!!

Trust me you would know if you had a 2 stroke. There are very few street bikes that are 2-strokes. Also 2-strokes do not have valves. And you must mix the oil with the gas on a 2 stroke. Therefore, I am virtually positive you have a 4 stroke.

It is a 4 stroke. If you want more info on your bike this is a very informative site. http://home.online.no/~ivbekkel/history.cfm
