• If the dead play is not correct, loose the lock nut (2) at the end of the
thrott le cable, rotate de adjuster (3) unti l its correct.
• Tighten the lock nut.

and reinstall protector.

4.-SPARK PLUG

The standard spark plug (Denso W24ESR-U o NGK BR8EG) must be ti ghtened
to 25 Nm.
The spark plug must be removed periodically to check electrodes gap (0,7~0,8
mm). If the spark plug contains oil or cinder, clean with a wire brush or similar.
Measure the electrodes gap with a gauge and adjust, if it is incorrect, by bending
the outer electrode. If spark plug electrodes are rusty, damaged, or isolati on is
broken, change spark plug.
NOTE: Inspect every 10 hours and replace every 20 hours.
To fi nd the correct temperature which must operate the spark plug, remove it
and examine ceramic isolator around the electrode. If ceramic has a light brown
color, spark plug temperature harmonizes with the engine. If ceramic is white,
spark plug must be replaced by a colder one. If it is black must be replaced by a
hott er one.
NOTE: If the engine performance drops, replace the spark plug to regain engine
performance.
