Spark Plug - KYMCO XCITING 250 Owner's Manual

SPARK PLUG

Remove the carbon deposits from the spark plug with a small wire
brush or a spark plug cleaning machine. Readjust the spark plug gap
to specified limit by using a spark plug gap thickness gauge. The
spark plug should be replaced periodically. Whenever removing the
carbon deposits, be sure to observe the operational color of the
spark plug's porcelain tip. This color tells you whether or not the
standard spark plug is suitable for your type of usage. A normal
operating spark plug should be light brown or tan color. If the spark
plug is very white or glazed appearing, then it has been operating
much too hot. This spark plug should be replaced with the colder
plug.
An improper spark plug may have an incorrect fit or heat
range for your engine. This may cause severe engine
damage which will not be covered under warranty.
Never use a spark plug with an improper heat range.
Severe engine damage could result.
