The 97 formula Z 583, that has to be the best built machine for its time. The motor has never had anything changed other then spark plugs and it always runs, and it has to be the fastest 600 ever! I mean i have run down polaris, AC, Yamaha, ski-doo 440, 500, 600, 700's. I mean it smokes, I should put its engine in my 440 frame.
