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 10000 km (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.
