Cleaning and changing air filters (fig. 27.2)
The air box is accessible after removing the body panels
and the headlamp fairing (see pages 36 and 37).
Undo the eight fastening screws of the outer cover (1,
fig. 27.1). Remove the cover but leave it hanging from
the turn indicator cable. Do not remove the reduction
element (4) from its seat.
Remove the filter (2, fig. 27.2) from its seat on the inner
cover (3).
Clean the filter cartridge with compressed air or fit a new
E
one, if needed.
Important
A dirty filter will reduce air intake, increase fuel
consumption, reduce engine power, and foul the spark
plugs. Do not use the motorcycle without filter or
suspended matters could get into the engine and cause
damage.
Install the filter properly into its seat on the inner cover
and refit all the parts you have removed.
Important
If you are using the motorcycle on dusty or very
wet roads, replace filter more frequently than
recommended intervals shown in the routine
maintenance chart (see Warranty Card).
