PARK PLUGS
The motorbike is equipped with NGK BPR 6 ES spark
plugs with a distance of 0,7 mm between the electrodes.
The spark plugs must be removed from time to time for
cleaning and for checking the distance between the
electrodes.
N.B.
Values lower than 0,7 mm can compromise the
engine lifespan.
When reinserting the spark plugs, make sure that they fit
perfectly and that they can be tightened easily in their
seats; an incorrect fitting will damage the threading on the
heads; it is therefore advisable to tighten them by hand
for some turns and then, using the special key (supplied
with the motorbike), tighten them to the torque prescribed
in the table in chapter 4, section B.
N.B.
Always replace and refit the spark plugs only when
the engine is cold.
Even if the spark plugs seem to be in excellent condition,
after about 6000 mi, they must be replaced as described
in the periodical maintenance table, chapter 1 in this
section.
WARNING
In order to prevent irregular functioning and
inefficiency of the ignition system, make sure that
the spark plug wire connections (spark-plug caps)
and the spark plugs are the recommended type
(like the original ones).
Do not check the current on the spark plugs
without inserting the spark plug caps originally
provided, as this operation could cause
irreparable damage to the ECU.
