It is very useful to examine the state of the spark
plug just after it has been removed from the engine
since the scale deposits on the plug and the colour
of the insulator provide useful indications.
Correct heat rating:
The tip of the insulator should be dry and the colour
should be light brown or grey.
High heat rating:
In this case, the insulator tip is dry and covered with
dark deposits.
Low heat rating:
In this case, the spark plug has overheated and in-
sulator tip is vitrified (glazed), white or grey in col-
our.
CAUTION*: Carefully change the spark plug, if
necessary, using one having the same rating.
before refitting the plug, thoroughly clean the
electrodes and the insulator using a metal
brush. Smear some graphite grease on spark
plug thread, do it fully home finger tight

then tighten it to 10÷12 Nm - 1,019÷1,22 Kgm -
7,37÷8,85 ft/lb. torque. Loosen the spark plug
then tighten it again to 10÷12 Nm - 1,019÷1,22
Kgm - 7,37÷8,85 ft/lb.
Spark plugs which have cracked insulators or
corroded electrodes should be replaced.
TYRE CHECK AND/OR REPLACEMENT
This motorcycle is equipped with tyres with air
chamber.
WARNING*: The wheels have been designed to
mount tyres with air chamber. It is prohibited
to mount tyres without air chamber.
- Check the condition of the tyres; they may not
have any cracks, grazes, etc. Also check the state
of wear of the tread by means of the indicators on
the tyre.
MINIMUM HEIGHT OF THE TREAD
0.12 in. (SILVER VASE)
FRONT 0.12 in. (GRAN TURISMO)
0.08 in. (GRAN MILANO)
0.12 in. (SILVER VASE)
REAR 0.12 in. (GRAN TURISMO)
0.08 in. (GRAN MILANO)
- Check the tyre pressure which should be as indi-
cated under TECHNICAL DATA.
WARNING*: The front and rear tyre must be
of the same brand and model. Using different
types of tyre for the front and rear will com-
promise motorcycle stability and handling.
Note*: Tyres age even if they do not visibly appear
worn; cracks in the sides or deformation of the tyre
body are a sign of ageing.Have the tyres checked by
a tyre dealer before using the motorcycle.
WARNING*: Using the motorcycle with the
tyres inflated to an incorrect pressure or with
worn or deteriorated tyres may cause serious
injury or death if losing control of the motor-
cycle.
