Tools and Materials Needed

  • Gap tool
  • Rag or cloth

Step-by-Step Guide

Step 1: Prepare the Bike

Ensure the bike is on a stable surface and the engine is cool to the touch. This will prevent any accidental burns and make the process easier.

Step 2: Locate the Spark Plug

The spark plug on the Yamaha PW50 is located on the right side of the engine. You may need to remove the plastic cover to access it.

Step 3: Remove the Old Spark Plug

Use the spark plug socket wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is loose enough to remove by hand. Be cautious not to damage the surrounding area.

Step 4: Check the Spark Plug Gap

Before installing the new spark plug, use a gap tool to ensure the gap is set to the manufacturer's specifications. For the PW50, the gap should be 0.024 inches (0.6 mm).

Step 5: Install the New Spark Plug

Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once it is hand-tight, use the socket wrench to snug it up. Do not over-tighten as this can damage the threads.

Step 6: Reattach the Spark Plug Cap

Firmly press the spark plug cap back onto the new spark plug until it clicks into place. Ensure it is secure to prevent any misfires.
