Steps to Change the Spark Plug
- Preparation: Ensure the engine is cool to prevent burns. Place the bike on a stable surface using a stand.
- Remove the Seat: Use a wrench to remove the bolts securing the seat. Lift the seat off to access the spark plug area.
- Locate the Spark Plug: The spark plug is located on the right side of the engine. Remove the spark plug cap by pulling it straight off.
- Remove the Old Spark Plug: Use the spark plug socket wrench and ratchet to unscrew the old spark plug. Turn counterclockwise to remove it.
- Check the Gap: Use a gapping tool to ensure the new spark plug is gapped correctly. The gap should be 0.6-0.7mm.
- Install the New Spark Plug: Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Tighten with the socket wrench until snug, then give it an additional 1/4 turn.
