Steps to Change the Spark Plug

  1. Preparation: Ensure the engine is cool to prevent burns. Place the bike on a stable stand to keep it upright.
  2. Remove the Spark Plug Cap: Locate the spark plug cap on the top of the engine. Gently pull it off to expose the spark plug.
  3. Remove the Old Spark Plug: Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free.
  4. Check the Spark Plug Gap: Before installing the new spark plug, use a gap tool to ensure the gap is set to the specifications in your owner's manual. Adjust if necessary.
  5. Install the New Spark Plug: Apply a small amount of anti-seize compound 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 spark plug socket and ratchet to snug it up. Do not over-tighten.
  6. Reattach the Spark Plug Cap: Push the spark plug cap back onto the new spark plug until it clicks into place.
