Part: Spark plugs

Video tutorial

To change the spark plugs on a Kawasaki Z900RS, follow these steps. First, ensure the motorcycle engine is cold.

Next, locate the spark plugs on the engine, positioned on the top of the engine near the cylinder head. Using a spark plug socket, carefully unscrew the spark plugs from their housing.

Take care not to damage the threads of the spark plugs or the cylinder head holes. Before installing the new spark plugs, check that they are the correct size and that the gap (distance between the electrodes) is set correctly.

Screw the new spark plugs into the housing, ensuring not to overtighten to avoid damage. Finally, reconnect the spark plug leads and ensure they are securely attached to the spark plugs.

Once the spark plug replacement is complete, start the engine and check that everything is functioning correctly.
