Lubricating cables and joints
The condition of the outer sheath of the throttle/starter
cable should be checked at regular intervals. The sheath
should show no signs of squeezing or cracking.
Work the controls to make sure the cable slides
smoothly inside the sheath: if you feel any friction or
hard spots, have the cable replaced by a Ducati Dealer or
Authorized Workshop.
To prevent these failures, smear the end of the Bowden
cable with SHELL Advance Grease or Retinax LX2 at
E
regular intervals.
For the throttle cable, it is best to open the device by
unscrewing the two fastening screws (1, fig. 31) and
then grease the cable ends and the pulley.
Warning
When refitting the cover, be sure to slide the cable
onto the suitable pulley.
Refit the cover and tighten the screws (1).
To ensure smooth operation of the side stand joint,
clean off any dirt and apply SHELL Alvania R3 at all
points exposed to friction.

The throttle twistgrip must have a free play of 1.5 - 2 mm
measured at the edge of the twistgrip, at all positions of
the handlebars. If it needs adjusting, use the suitable
adjuster (2, fig. 31) provided on the throttle control.
