The standard spark plug for these
motorcycles has been carefully
selected to meet the vast majority of
all operational ranges. If the spark
plug color indicates that other than a
standard spark plug be used, it is
best to consult your
Hyosung
dealer
before selecting an alternate plug or
heat range. The selection of an
improper spark plug can lead to
severe engine damage.
CAUTION
Remove the carbon deposits periodically
from the spark plug with a piece of hard wire
