2.10 THROTTLE
Inspect after the first 1000 km (625 mi) and every 7500
km (4687 mi) or 8 months afterwards.
2.10.1 CHECKING FOR THROTTLE PROPER
OPERATION
CAUTION
Throttle operation may be impaired when the throttle
cables are damaged, bent in tight turns or twisted.
Using the motorcycle in this condition may lead to
loss of control while riding.
Turn the handlebars and ensure that idling speed is
unaffected by handlebar movement. Open the throttle
and ensure that the twistgrip snaps closed smoothly
when released.
If needed:
&
Make sure the components listed below are in the
proper position and well lubricated:
- cable housing;
- twistgrip adjuster (1);
- throttle body adjusters (2);
- throttle body axle (3);
- cable end-caps;
- throttle control.
&
Check throttle cable play adjustment, see 2.10.3
(THROTTLE CABLE PLAY ADJUSTMENT).
2.10.2 IDLING ADJUSTMENT
Manual adjustment for idling speed is not provided.
Idling is adjusted automatically through a stepper motor
(1) that operates a small piston inside an air passage.
The position of the piston inside the air passage is
determined by the on-board computer according to three
parameters:
- throttle position;
- engine rpm;
- coolant temperature.
