The throttle grip in all steering positions must have free play, measured on the periphery of the flange of the grip, of 1.5 - 2.0 Mm.

If necessary, adjust using the adjusters (1) and (2) located on the steering tube on the right side of the motorcycle.
Adjuster (1) adjusts the throttle opening control, while adjuster (2) adjusts the throttle closing control.
Note
The throttle cables are distinguished by the writings in different colours on them:

Slip the rubber gaiters (3) off the adjusters and loosen the check nuts (4).
Adjust both adjusters by the same amount: turn clockwise to increase free play and counter clockwise to reduce free play.
When finished, tighten the counter nuts and refit the protection gaiters (3) to the adjusters.
Periodically check the condition of the outer cables of the throttle opening (1) and closing cables (2). The plastic covering should show no signs of pinching or cracking.
Lubricate the ends of the inner cables with the specified grease periodically to ensure they run freely.

Operate the control to check that the inner cable slides smoothly inside the outer cable: if you feel excessive resistance or stiffness, renew the cable.
To lubricate the throttle grip, it is necessary to slide off the protection cover (a), loosen the screws (7) and remove the covers (5) and (6) of the throttle grip.

Lubricate the ends of the cable and the pulley (b) with the recommended grease.
When refitting the cover, make sure that the cables are correctly positioned in the pulley (b).

Place the covers (5) and (6) in the reference hole of the handlebar.
Fix covers (5) and (6) by tightening the screws (7) to a torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings).
