CRF230F
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 (2). Minor free play
adjustments are made with the upper adjuster (3).
To adjust free play, loosen the lock nut (4) or (5),
and turn the adjuster (2) or (3). 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.
