What Causes Excessive White Carbon Deposits on Motorcycle Spark Plugs?
1 Answers
Motorcycle spark plugs accumulate excessive carbon deposits primarily due to burning engine oil, poor-quality gasoline, overly rich air-fuel mixture from various causes, carburetor malfunctions, frequent low-speed or short-distance riding, and repeated startups. When severe carbon buildup occurs, simply replacing the spark plug with a new one suffices. As part of the engine's ignition system, spark plugs are wear-prone components requiring periodic replacement. Key ignition system components include the ignition coil and spark plugs. Motorcycle spark plug replacement procedure: 1. Locate the cylinder head position and identify the spark plug cap. Before removal, use compressed air to clean surrounding areas, preventing debris from falling into the combustion chamber through the installation hole during spark plug removal. 2. Use the onboard/specialty tool to rotate the spark plug counterclockwise. If no dedicated removal tool is available, a wrench can alternatively perform this counterclockwise rotation. 3. Manually extract the spark plug for inspection and cleaning. Note that onboard tools lack magnetic retention or fixed bases, potentially causing dropped spark plugs during extraction. 4. After removing the old spark plug, install the new one by reversing the removal steps.
