MAINTENANCE
SPARK PLUG SERVICE:
a) Remove the spark plug using a spark plug socket wrench.
b) Clean the electrodes with a metal brush and remove any carbonaceous build-up.
c) Using a thickness gauge, check for the right gap (0.6-0.8mm) between the electrodes.
d) Install the spark plug and tighten with a socket wrench.
Replace the spark plug if the electrodes are burnt or if the porcelain is broken or damaged.
WARNING: Fire hazard! Do not check the ignition system with spark plug removed.
IMPORTANT: Use only spark plugs of the recommended type.
TUNING THE THROTTLE CABLE AND THE CARBURETOR:
Should the engine not reach maximum revs with the throttle trigger set to “FAST”, it could be due to the
throttle trigger and speed control lever being out of phase or to a carburetion problem. Go to a specialised
center or contact your dealer to restore normal operation.
