9.3 Spark plug maintenance.

Recommended spark plugs: TORCH F6RTC, NGK BP7ES, BOSCH WR3C.
1 Remove the cap of spark plug, pulling it out.
2 With a spark plug wrench unscrew and remove the spark plug from the
engine (turn counterclockwise).
3 Visually check the spark plug. If the spark plug insulation is cracked or
chipped, replace it with a new one. To clean dirt on the electrode, use a
very thin wire brush.
4 Check the electrode distance with a caliper. The distance should be
between 0.6 and 0.7mm. If it does not match, adjust it carefully.
5 Carefully put back the spark plug, starting its threading manually to avoid
the damage of the thread. With the spark plug fully threaded make a final
tightening with a spark plug wrench, according to the following
recommendations:
• New spark plugs: 1/2 turn
• Used spark plugs: 1/8 to 1/ 4 turn
6 Put back the cap of the spark plug.
NOTE: The spark plug must be firmly tightened. An incorrectly fitted spark
plug can heat up and even damage the engine. On the other hand, over-tightening
can damage the spark plug and damage the thread of the cylinder head.
