Also, inspect the air suction valves whenever stable idling cannot be obtained, engine power is greatly reduced, or there is abnormal engine noise. Air suction valve removal and inspection should be done only by a competent mechanic following the instructions in the Service Manual. A clogged air cleaner restricts the engine's air intake, increasing fuel consumption, reducing engine power, and causing spark plug fouling. This motorcycle's air cleaner element consists of a wet paper filter, which cannot be cleaned. The air cleaner element must be replaced in accordance with the Periodic Maintenance Chart. In dusty, rainy, or muddy conditions, the air cleaner element should be serviced more frequently than the recommended interval. Air Cleaner NOTICE Use only the recommended air cleaner element (Kawasaki part number 11013-0031). Using the any other air cleaner element will wear the engine prematurely or lower the engine performance.
