03Step-by-Step Guide to Replace Motorcycle Spark Plugs

  • Start by ensuring that the engine is cool before attempting to replace the spark plugs.
  • Locate the spark plug wires or ignition coils. Depending on your motorcycle model, you may need to remove a cover or fairing to access them.
  • Carefully remove the spark plug wires or ignition coil connectors from the spark plugs. Remember the order in which they were connected, as you will need to reconnect them correctly later.
