Honda CRF230F Owner's Manual page 78

Free Play Adjustment:
Measure the throttle grip free play at the
throttle grip flange.
The standard free play should be
approximately:
2 – 6 mm (0.1 – 0.2 in)
Major free play adjustments, such as after
replacing the throttle cables or removing the
carburetor, are made with the lower adjuster
(3). Minor free play adjustments are made
with the upper adjuster (5). To adjust free
play, loosen the lock nut (2) or (4), and turn
the adjuster (3) or (5).
Tighten the lock nut after adjustment.
After adjustment, check again for smooth
rotation of the throttle grip from the fully
closed to the fully open position with the
steering to the full right and left as well as
straight ahead.
If proper throttle free play cannot achieved,
contact your Honda dealer.
