SPARK PLUG
Your motorcycle comes equipped
with DENSO X22EPR-U9 or NGK
DPR7EA-9 spark plugs. To deter-
mine if the standard spark plug is
right for your usage, check the
color of the plug's porcelain cen-
ter electrode insulator after motor-
cycle operation. A light brown
color indicates that the plug is cor-
rect. A white or dark insulator indi-
cates that the engine may need
adjustment, or another plug type
may be needed. Consult your
authorized Suzuki dealer or quali-
fied mechanic if your plug insula-
tor is not a light brown color.
CAUTION
An improper spark plug may
have an incorrect fit or heat
range for your engine. This
may cause severe engine dam-
age which wil not be covered
under warranty.
~se one of the spark plugs
listed below or equivalent.
Consult your authorized
SUZUKI dealer or qualified
mechanic if you are not sure
which spark plug is correct for
your type of
usage. .
