SPARK PLUGS

NOTE: Always use the recom-
m e n d e d s p a r k p l u g s i n t h e
engine. See the appropriate spec-
ifications chart for correct spark
plug gap.
Varying terrain conditions and oper-
ating usage may require spark plugs
of a different heat range. For exam-
ple, sustained cross-country riding
will usually require colder heat-
range spark plugs while trail riding
or other continual slow speed opera-
tion will usually require hotter heat-
range spark plugs.
