I'm still in my stroll down memory lane and becoming sentimental today about the demise of two strokes at the world level. I talked to Rich Oliver about a month ago (look him up if you don't know who he is) about buying his world-dominating personal TZ250. The price was too high for me, unfortunately.
I just dug up this old article about Rich and his bike. He does a great job explaining the beauty of the 2-T GP engine.
