Fuel System (DFI)
Throttle Control System Inspection
Check the throttle grip free play [A].
If the free play is incorrect, adjust the throttle cable.
Throttle Grip Free Play
2 ∼ 3 mm (0.08 ∼ 0.12 in.)
Check that the throttle grip moves smoothly from full open
to close, and the throttle closes quickly and completely by
the return spring in all steering positions.
If the throttle grip doesn't return properly, check the throt-
tle cable routing, grip free play, and cable damage. Then
lubricate the throttle cable.
If necessary, adjust the throttle cable as follows.
Loosen the locknuts [A] and screw the adjusters [B] all the
way in so as to give the throttle grip plenty of play.
Turn out the adjuster of the decelerator cable [C] until
there is no play.
Tighten the locknut against the adjuster.
Turn the adjuster of the accelerator cable [D] until the
proper amount of throttle grip free play is obtained and
tighten the locknut against the adjuster.
Idle Speed Inspection
Start the engine and warm it up thoroughly.
At first the engine will run fast to decrease warm up time
Gradually the fast idle will lower to a certain RPM auto-
matically. This is the idle speed.
With the engine idling, turn the handlebar to both sides.
If handlebar movement changes the idle speed, the
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 or Cable, Wire, and Hose Routing section in
the Appendix chapter).
Operation with an improperly adjusted, incorrectly
routed or damaged cables could result in an unsafe
riding Condition. Follow the service manual to be
make sure to correct any of these conditions.
Check the idle speed.
If the idle speed is out of the specified range, adjust it.
