Changing the original position of the clutch lever
The adjusting screw
1
can be used for individual adjustment of the original
position of the clutch lever, thus allowing adjustment to an optimal position
for every hand size.
Turning the adjusting screw clockwise reduces the distance between the
clutch lever and the handlebar. Turning the adjusting screw counterclock-
wise increases the distance between the clutch lever and the handlebar.
!
CAUTION
!
A
DJUSTMENT OF THE CLUTCH LEVER POSITION IS ONLY POSSIBLE WITHIN CERTAIN LIMITS
.
O
NLY TURN THE ADJUSTING SCREW MANUALLY AND NEVER APPLY EXCESSIVE FORCE

Adjust the throttle cable *
When starting to turn the throttle grip, you should feel an initial backlash of
3-5 mm (0.12-0.2 in).
If a correction is necessary, start by removing the tank. Slide back the
protection cover
5
. To set the backlash, loosen the counter nut
6
and turn
the adjusting screw
7
accordingly. Then, fasten the counter nut and slide
the protection cover back on.
Make sure that the throttle grip will return to the idle position automatically
once you let go of it.
To check the correctness of this setting, start the engine, turn the handlebar
left and right, in both cases as far as it will go. This must not cause any
changes in idling speed. Otherwise, you have to increase the backlash of
the throttle cable.
