MAINTENANCE AND ADJUSTMENT 95 Valve Clearance Valve and valve seat wear decrease valve clearance, upsetting valve timing. Engine Air Cleaner A clogged engine air cleaner restricts the engine's air intake, increasing fuel consumption, reducing engine power. NOTICE If valve clearance is left unadjusted, wear will eventually cause the valves to remain partly open; which lowers performance, burns the valves and valve seats, and may cause serious engine damage. Valve clearance for each valve should be checked and adjusted in accordance with the Periodic Maintenance Chart. Inspection and adjustment should be done by an authorized Kawasaki dealer. Valve Clearance (EX & IN.) : 0.20 mm (0.008 in.) WARNING A clogged air cleaner may allow dirt and dust to enter the fuel injection system and the throttle may stick resulting in a hazardous operating condition. Clean the air filter according to the periodic maintenance chart; more often if the vehicle is used in extremely dusty conditions. j NOTICE A clogged air cleaner may allow dirt and dust to enter the engine causing excessive wear and possible engine damage. The engine air filter restriction gauge shows whether the air cleaner is clogged. Whenever the red band shows in the gauge window, the air cleaner element should be cleaned. After servicing the air cleaner element, the restriction gauge should be reset by pushing the button at the end of the gauge.
