Kawasaki Ninja Owners Manual: Kawasaki Clean Air System

Kawasaki Ninja Owners Manual / Maintenance and adjustment / Kawasaki Clean Air System

The Kawasaki Clean Air System (KCA) is a secondary air suction system that helps the exhaust gases to burn more completely. When the spent fuel charge is released into the exhaust system, it is still hot enough to burn. The KCA System allows extra air into the exhaust system so that the spent fuel charge can continue to burn.

This continued burning action tends to burn up a great deal of the normally unburned gases, as well as changing a significant portion of the carbon monoxide into carbon dioxide.

Air Suction Valves

The air suction valve is essentially a check valve which allows fresh air to flow only from the air cleaner into the exhaust port. Any air that has passed the air suction valve is prevented from returning. Inspect the air suction valves in accordance with the Periodic Maintenance Chart. Also, inspect the air suction valves whenever stable idling cannot be obtained, engine power is greatly reduced, or there are abnormal engine noises.

Air suction valve removal and inspection should be carried out only by a competent mechanic following the instructions in the Service Manual.

Valve Clearance
Valve and valve seat wear decreases valve clearance, upsetting valve timing. NOTICE If valve clearance is left unadjusted, wear will eventually cause the valves to remain partly open; which lowe ...

Technical Information-Power Mode
The rider can choose from three engine power modes to suit their preferences and road conditions. The FI ECU controls the engine power by adjusting fuel injection, air intake, and ignition timing. It enables three-mode selection: Full Power (Mode F), Middle Power (Mode M), and Low Power (M ...

Sprocket Wear Inspection
Visually inspect the engine and rear sprocket teeth for wear and damage. If the teeth are worn as illustrated, replace the sprocket, and inspect the drive chain wear (see Drive Chain Wear Inspection in the Periodic Maintenance chapter). Worn Tooth (Engine Sprocket) [A] Worn Tooth (Rear ...
