Tools and Materials Needed

  • Spark plug socket wrench
  • New spark plug (NGK BPR7HS recommended)
  • Socket wrench extension (optional)
  • Gapping tool
  • Clean cloth

Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your Yamaha PW80 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it off the spark plug cap.

Step 2: Remove the Old Spark Plug

Use the spark plug socket wrench to loosen and remove the old spark plug. If the plug is difficult to reach, use a socket wrench extension for better access. Once removed, inspect the old plug for any signs of wear or damage.

Step 3: Check the Gap on the New Spark Plug

Before installing the new spark plug, use a gapping tool to ensure the gap is set to the manufacturer's specifications. For the PW80, the gap should be approximately 0.6-0.7mm.

Step 4: Install the New Spark Plug

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

Step 5: Reattach the Spark Plug Wire

Reconnect the spark plug wire to the new spark plug, ensuring it is securely attached. Wipe down any dirt or debris from the area with a clean cloth.
