Steps to Remove and Install Spark Plugs
- Step 1: Start by ensuring your motorcycle’s engine is cool to avoid any burns.

- Step 4: Attach the appropriate spark plug socket to a ratchet or extension bar.
- Step 5: Insert the spark plug socket onto the spark plug and turn it counterclockwise to loosen and remove the old spark plug.
- Step 6: Once the old spark plug is removed, inspect it for any signs of wear or damage. If necessary, replace it with a new spark plug of the same type and heat range.
- Step 7: Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the future.
- Step 8: Carefully insert the new spark plug into the spark plug socket and hand-tighten it into the cylinder head.
- Step 9: Use the spark plug socket and ratchet to tighten the spark plug until it is snug. Avoid overtightening, as it can damage the spark plug or cylinder head.
- Step 10: Reconnect the spark plug wires to their respective spark plugs, ensuring they are securely attached.
- Step 11: Repeat the above steps for each spark plug on your Harley-Davidson motorcycle.
