Steps to Change the Spark Plug

  1. Preparation: Ensure the engine is cool to prevent burns. Disconnect the spark plug wire by pulling the boot off the plug.
  2. Remove the Old Spark Plug: Use the spark plug socket and ratchet wrench to unscrew the old spark plug. Turn counterclockwise until it is free.
  3. Check the Gap: Use the gap tool to measure the gap on the new spark plug. The correct gap for the 2004 Yamaha BANSHEE is 0.7-0.8 mm. Adjust if necessary.
  4. Apply Anti-Seize: Lightly coat the threads of the new spark plug with anti-seize compound to prevent it from seizing in the engine.
  5. 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 socket and wrench to snug it up. Do not over-tighten.
  6. Reconnect the Spark Plug Wire: Push the spark plug wire boot back onto the new spark plug until it clicks into place.
