LUBRICANT TABLE
NOTE -
The vehicle’s life depends also on the care devoted to lubricating it.
SPARK PLUG
Replace every 5,000 km (3,120 mi)
The spark plug is an essential component:
1 - Proper care of the plug is important for maintaining
the engine in perfect working order.
2 - For maintenance, remove the centre partition under
the seat
(P-Fig. 23)
, by unscrewing the three fixing
screws
(V-Fig. 24)
(2 on the footboard and one
inside the helmet compartment) and raising the bot-
tom profile (with the aid of a screwdriver) sealed
onto the two teeth of the footboard. Carefully
remove the cap by turning it clockwise and anti-
clockwise alternatively
(C-Fig. 24)
; now, unscrew
the spark plug using the special wrench supplied
with the vehicle (all operations on the spark plug
must be performed when the engine is cold).
3 - Examine the spark plug conditions after a reasona-
bly long drive (10-15 km) and after letting the
engine cool down (at least 10-15 minutes), since
the sediments and the colour of the insulator can
provide useful information about the heat rating of
the spark plug, carburetion, lubrication and general
conditions of the engine. A light brown colour of the
insulator, around the central electrode, indicates
good working order.
4 - After disassembling the spark plug, suitably clean
the electrodes and the insulator using a metal
brush. Adjust the electrode gap using a filler gauge:
the gap should range from 0,5 ÷ 0,6 mm.
5 - Blow onto it so as to prevent possible residues from
entering the engine, then refit it, by wrenching until
finger tight. Then, using the special spark plug
wrench, wrench it to the recommended torque
wrench setting:
17.5 Nm / 1.75 kgm
.
Spark plugs with a heat rating differing from
the recommended one may seriously damage
the engine.
It is imperative that any spark plug exhibiting
cracks on the insulator or corroded electrodes
be replaced.
THROTTLE FREE PLAY ADJUSTMENT
Check that the throttle grip idle stroke is 1-3 mm (meas-
ured on the end of the throttle grip).
