SPARK PLUG

Your motorcycle comes equipped
with a DENSO
X22ESR-U (California) or NGK
DPR7EA-9, DR7EA (California)
spark plugs. To determine if the
standard spark plug is right for
your usage, check the color of the
plug's porcelain center electrode
insulator after motorcycle opera-
tion. A light brown color indicates
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.
NOTICE
An improper spark plug may
have an incorrect fit or inappro-
priate heat range for your
engine. This may cause severe
engine damage which may not
be covered under warranty.
Use one of the spark plugs
listed or their equivalent. Con-
sult your Suzuki dealer if you
are not sure which spark plug
is correct for your type of
usage.
