throttle cables may be improperly adjusted or incorrectly
routed, or damaged. Be sure to correct any of these
conditions before riding (see Throttle Control System
Inspection and Cable, Wire, and Hose Routing section in
the Appendix chapter).
Operation with improperly adjusted, incorrectly
routed or damaged cables could result in an unsafe

make sure to correct any of these conditions.
Check the idle speed.
1 100 ±100 r/min (rpm)
Idle Speed Adjustment
This motorcycle is equipped with the idle speed control
system. The idle speed is adjusted automatically at the
specified value (1 100 r/min (rpm)) by the idle speed
control system. Therefore, it is not necessary to adjust
the idle speed normally.
Throttle Control System Inspection
Check that the throttle grip [A] moves smoothly from full
open to close, and the throttle closes quickly and com-
pletely by the return spring in all steering positions.
If the throttle grip does not return properly, check the throt-
tle cable routing, grip free play, and cable damage. Then
lubricate the throttle cable.
Check the throttle grip free play [B].
Throttle Grip Free Play
2 ∼ 3 mm (0.08 ∼ 0.12 in.)
If the free play is incorrect, adjust the throttle cable as
Loosen the locknuts [A] [B].
Screw both throttle cable adjusters [C] [D] to give the
throttle grip plenty of play.
Turn the decelerator cable adjuster [C] until there is no
play when the throttle grip play completely closed.
Tighten the locknut [A].
Turn the accelerator cable adjuster [D] until 2 ∼ 3 mm
(0.08 ∼ 0.12 in.) of throttle grip play is obtained.
Tighten the locknut [B].
If the free play can not be adjusted with the adjusters,
replace the cable.
