AIR FILTER CHECK AND/OR REPLACEMENT
-
Remove the front fairing by unscrewing the retaining
screws (1) (one per side) and the screws (2).
-
Unscrew the screw (3) and remove the filter cover (4).
-
Remove the filter (5) and check its condition; to clean
it, blow it with compressed air; if it is very dirty,
replace it.
-
Refit all components following removal operations in
reverse order.
SPARK PLUG CHECK
Spark plug gap must be 0.7 ÷ 0.8 mm (0.02 ÷ 0.03 in).
A greater gap may cause starting difficulties and coil
overload, a shorter gap may cause problems with
acceleration, idling and low speed performance.
To reach the spark plug, carry out the following
removal operations:
-
remove the side panels;
-
remove the front fairing;
-
remove the tank plug;
-
remove the tank cover;
-
overturn the frame and the tank;
-
remove the filter box.
CAUTION
As this procedure is quite complex, it is
advised to contact an SWM Dealer for
spark plug check/replacement.
IT is very useful to examine the status of the spark
plug just after it has been removed from its seat, since
the deposits and the colour of the insulator provide
useful information.
Correct heat rating:
The tip of the insulator is dry and the colour is 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
insulator tip is vitrified (glazed), white or grey in colour.
