Kawasaki Ninja Owners Manual: Air Cleaner

Kawasaki Ninja Owners Manual / Maintenance and adjustment / Air Cleaner

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.

NOTICE

Use only the recommended air cleaner element (Kawasaki part number 11013-0041). Using the other air cleaner elements will wear the engine prematurely or lower the engine performance.
