How to Replace the Spark Plug on a Kawasaki KX 450?

Model: Kawasaki Kx 450f
Part: Spark plugs

Video tutorial

To replace the spark plug on the Kawasaki KX 450, you need to loosen the screws that secure the seat to its housing so that it can be removed to access the underlying components. You will also need to loosen the screws that secure the fuel tank, removing it from its position after disconnecting hoses and connectors.

This will provide access to the coil at the top of the engine block cylinder, which can be removed to access the spark plug underneath: the spark plug can now be extracted from its seat using the appropriate socket wrench and replaced with a new one.
