Use only the recommended spark plugs.
Spark plugs which have an different heat
range may cause engine damage.
If the spark plug(s) is fouled, has carbon
build up, or is worn, it should be
replaced.
When reusing spark plugs, remove dirt
from the electrodes and check the spark
plug gap.
1. Stop the engine.
2. Remove the top cowl.
3. Remove the spark plug caps.
