2001 AMA 2S0cc Supercross, 2S0cc Motocross and 12Scc Motocross Champion. Kawasaki has won 21 titles in the last decade, almost twice as many as any other manufacturer dunng the some time period. Kawasaki's pro motocross team has also won two or more championships in each of the last six seasons. Now that's domination. oAII-new Kawasaki integrated Power-valve System (KIPS) features a simpler 2-piece slider-type exhaust valve that opens faster and creates a larger timing gap between the main and subvalves for more mid-range power. °The slide-type KIPS power valve sits lower in the exhaust port with a smaller frontal orea focing the piston that helps reduce resistance for the exhaust. oNew, shorter stroke governor arm with lighter spring matches the smaller face of new KIPS valve. oBy reshaping the exhaust port window and widening it 2mm, the exhaust can exit the cylinder quicker for a noticeable punch in low and mid-range power. oThe bottom end of the connecting rod features a wider oil groove for improved oil flow and greater reliability. The bottom end bearing is now 72mm for reduced creep and improved durability. 26 DECEMBER 5, 2001 • cue I e n e _ s
