Step 1: Locate the Spark Plug

The spark plug on the 1979 Honda Z50 is located on the right side of the engine. Ensure the engine is cool before starting the replacement process to avoid burns.

Step 2: Remove the Spark Plug Cap

Gently pull the spark plug cap off the plug. Be careful not to damage the cap or the wire connected to it.

Use the spark plug socket wrench to unscrew the old spark plug. Turn counterclockwise until it is loose enough to remove by hand. Inspect the old plug for any signs of damage or wear, which can indicate engine issues.
