Plug Replacement Guide
NOTE: This motorcycle uses a resis-
tor-type spark plug to avoid jamming
electronic parts. Improper spark plug
selection may cause electronic inter-
ference with your motorcycle’s ignition
system, resulting in motorcycle per-
formance problems. Use only the rec-
ommended spark plugs.
NOTICE
An improper spark plug may have
an incorrect fit or inappropriate
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. Consult your
Suzuki dealer if you are not sure
which spark plug is correct for
your type of usage.
