Spark Plug - Benelli Tornado TNT600 Owner's Manual

SPARK PLUG

In the initial 1000km driving and every 4000km interval, use the small metal wire or spark plug
cleaner to clear the carbon deposit on it. Use the spark plug gap-measuring plate to readjust
the spark plug electrode gap and keep it within 0.6-0.7mm. Replace the spark plug after every
8000km driving.
The spark plug shouldn't be screwed too tight to make the thread damage in case of damaging the thread of
cylinder cover. Don't let any other subjects to fall into the engine when disassembling the spark plug.
