Saf ety Precautions
Using spark plugs with an improper heat range
can cause engine damage.

in the recommended heat range.
The recommended standard spark plug is

periods at high speeds or near maximum power
(high engine rpm) in hot climates, or plan
extended riding in cold climates, a different
plug may be recommended.
