ADJUSTING THE ACCELERATOR
CONTROL (Fig. 49)
The accelerator control must have a slack such as to
allow the closing of the carburettor valve and of the
lubrication pump.
In order to obtain this, act on the special adjuster (1)
positioned at the beginning of the accelerator control
cable, after removing the protection element (2).
a
Perform this operation only after making
sure that the cables of the carburettor
and of the lubrication pump are properly
adjusted.

SPARK PLUG (Fig. 50)
Remember: 1 mile = 1.6 km
1 km = 0.625 miles.
Read page 50 carefully.
Change the spark plug every 6000 km.
Remove the spark plug and clean it carefully, remov-
ing carbon deposits; change it if necessary.
To remove and clean the spark plug:
– remove the saddle (see "GLOVE COMPART-
MENT" - page 23);
– raise the fuel tank (see "RAISING THE FUEL
TANK" - page 25);
– take off the spark plug cap;
– remove all the dirt from the base of the spark plug,
then unscrew it with the spanner you will find in the
tool kit and extract it from its seat, taking care that
neither dust nor other substances enter into the
cylinder.
If the spark plug is wet or very dark, replace it with a
new one having lower heat rating; on the contrary, if
the spark plug is too light, do just the opposite: a spark
plug that functions correctly should be light brown.
– Make sure that on the electrode and on the central
porcelain part there are neither carbon deposits,
nor corrosion marks; if necessary, clean them with
the special cleaners for spark plugs, with an iron
wire and/or a metal brush.
– Energetically blow some air, in order to prevent the
removed residues from getting into the engine.
