THROTTLE OPERATION
Reusing a damaged
or abnormally bent
or kinked throttle
cable can prevent
proper throttle slide
operation and may
lead to a loss of
throttle control
while riding.
Check for any deterioration or damage to the throt-
tle cable. Check the throttle grip for smooth opera-
tion. Check that the throttle opens and automatically
closes in all steering positions.
If the throttle grip does not return properly, lubricate
the throttle cable and overhaul and lubricate the
throttle grip housing.
For cable lubrication: Disconnect the throttle cable
at their pivot points with a commercially available
cable lubricant or a light weight oil.
If the throttle grip still does not return properly,
replace the throttle cable.
With the engine idling, turn the handlebar all the
way to the right and left to ensure that the idle
speed does not change. If idle speed increases,
check the throttle grip free play and throttle cable
connection.
Measure the throttle grip free play at the throttle
grip flange.
FREE PLAY: 2 - 6 mm (1/16 - 1/4 in)
Throttle grip free play can be adjusted at either end
of the throttle cable.
Minor adjustment are made with the upper adjuster.
Loosen the lock nut, turn the adjuster as required
and tighten the lock nut.
