damage.
Use only the recommended type of spark plug in the recommended heat
range.
To check the spark plug gap, use only a ‘‘wire-type feeler gauge.’’ To
prevent damaging the iridium coating of the center electrode, never
use a ‘‘leaf-type feeler gauge.’’
This ATV uses spark plug that have an iridium coated center electrode.
Be sure to observe the following when servicing the spark plug.
Do not clean the spark plug. If an electrode is contaminated with
accumulated objects or dirt, replace the spark plug with a new one.
Do not adjust the spark plug gap. If the gap is out of specification,
replace the spark plug with a new one.
