SPARK PLUG

To accede to spark plug, is necessary to 
take off saddle and the fuel tank.
To remove the fuel tank proceed as follows. 
Unscrew the two screws 

A

, unscrew the 

screw 

B

 (both side). Close the fuel tap (OFF 

position) and disconnect the pipe fuel 

C

 

from the fuel tap.

Lift the fuel tank.

Keeping the spark plug in good condi-
tion makes for reduced consumption and 
optimum engine performance.
It is advisable to remove the spark plug 
when the engine is hot (and naturally off) 
because the carbon formation and the 
colour of the insulator provide important 
information on carburetion, lubrication, 
and the general condition of the engine.

Note
Black spark plug = mixture is rich
Light brown spark plug = mixture is correct
White spark plug = mixture is lean

This operation must be performed with the 
utmost care to avoid severe hand burns. 
Always wear protective gloves.

To carry out the check, simply remove the 
current cap and then unscrew the spark 
plug using the spanner provided.
Carefully clean the electrodes using a 
wire brush. Blow the spark plug with com-
pressed air to prevent any residues from 
getting into the engine.
