with NGK MR8E-9 spark plug. 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 operation.

is correct. A white or dark insula-
tor indicates that the engine may
need adjustment, or another plug
type may be needed. Consult
your Suzuki dealer or a qualified
mechanic if your plug insulator is
not a light brown color.

have an incorrect fit or inappro-
priate heat range for your

be covered under warranty.
Use one of the spark plugs
listed or their equivalent. Con-
sult your Suzuki dealer if you
