SPARK PLUG & BRAKE FLUID INSPECTION
Spark plug
Remove the carbon deposits from the spark plug with a small wire brush or a spark plug cleaning machine. After cleaning (or when installing a new
spark plug) 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 colour of the removed spark plug’s porcelain tip. This colour tells you whether or
not the standard spark plug is suitable for your type of riding. Under normal usage, a spark plug's porcelain tip should appear light brown or tan in
colour.
If the spark plug porcelain tip is very white or glazed appearing, then the spark plug has been operating too hot. In such a situation, you should
replace the standard spark plug with a spark plug that has a colder heat range (usually a higher number; consult with your local authorized KYMCO
dealer when selecting an alternate spark plug).
Recommended spark plug
Spark plug type: CR7E (NGK)
Spark plug gap: 0.024 - 0.028 in
(0.6 - 0.7 mm)
CAUTION
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, as severe
engine damage may result.
