Tools and Materials Needed

Steps to Change the Spark Plug

  1. Preparation: Ensure the engine is cool to prevent burns. Place the bike on a stable stand for easy access.
  2. Remove the Spark Plug Cap: Gently pull the spark plug cap off the plug. Be careful not to damage the wire.
  3. Remove the Old Spark Plug: Use the spark plug socket wrench and ratchet to unscrew the old spark plug. Turn counterclockwise until it is free.
  4. Check the Gap: Before installing the new spark plug, use a gap tool to ensure the gap is set to 0.028 inches (0.7 mm). Adjust if necessary.
  5. Install the New Spark Plug: Apply a small amount of anti-seize lubricant to the threads of the new spark plug (optional). Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up. Do not over-tighten.
  6. Reattach the Spark Plug Cap: Push the spark plug cap back onto the new plug until it clicks into place.
