SPARK PLUG

Keeping the spark plug in good condition
will reduce fuel consumption and increase
engine performance.
To accede to spark plug, is necessary to
take off saddle and the fuel tank (page
64).
Examine the distance between the elec-
trodes with a feeler. This distance should
be from 0,5÷0,6 mm. If it is not, it may be
corrected by bending the earth electrode.
Check as well that there are no cracks in
the insulation or corroded electrodes. If so,
replace immediately.
When replacing the spark plug, screw it
in by hand until it stops, then tighten with
a wrench.
WARNING:
Do not check while the engine is hot.
