bar.
• Check that the throttle has a dead play of 2~3 mm.
• If the dead play is not correct, loose the lock nut at the end of the throttle
cable, rotate de adjuster until its correct.
• Tighten the lock nut.

• Check that the throttle has a dead play of 2~3 mm.
• If the dead play is not correct, loose the lock nut at the end of the throttle
cable, rotate de adjuster until its correct.
• Tighten the lock nut.
• If the dead play cannot be established by adjusting the cable, remove the
end cable protector in the carburetor, adjust with a tensor, tighten lock nut
and reinstall protector.

4.-SPARK PLUG

The standard spark plug (NGK R CR9E in 250/300cc. or NGK R CR8E in 450cc.)
must be tightened to 13 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 isolation is
broken, change spark plug.
NOTE: Inspect every 10 hours and replace every 20 hours.
To find 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
hotter one.
NOTE: If the engine performance drops, replace the spark plug to regain engine
performance.
