Today, you will learn how to remove and replace the spark plugs on a Kawasaki Ninja 250. After removing the seat and the fuel tank by unscrewing all the fastening bolts and disconnecting the fuel hose and the electrical connector, access the engine head: then remove the cap from your spark plug and unscrew it using a socket wrench with an extension. Once removed, replace it with the correct new one, and screw it in by hand before tightening with a wrench (preferably a torque wrench); all that’s left is to reassemble everything!
