SPARK PLUG
Your motorcycle comes equipped with
DENSO U20ESR-N or NGK CR6E
spark plugs. To determine if the stan-
dard spark plug is right for your usage,
check the color of the plug’s porcelain
center electrode insulator after motorcy-
cle operation. A light brown color indi-
cates that the plug is correct. A white or
dark insulator indicates that the engine
may need adjustment, or another plug
type may be needed. Consult your
authorized Suzuki dealer or a qualified
mechanic if your plug insulator 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 damage which will not be
covered under warranty.
Use one of the spark plugs listed
below or equivalent. Consult your
authorized SUZUKI dealer or a quali-
fied mechanic if you are not sure
which spark plug is correct for your
type of usage.
