The throttle twistgrip must have free play of 1.5×2.0 Mm in all steering positions, measured on the outer edge of the twistgrip. If necessary, adjust it using the adjusters (1 and 2, fig. 135) Located on the headstock on the right-hand side of the vehicle.
Adjuster (1) is for throttle opening, and adjuster (2) is for throttle closing.
Slip the rubber gaiters off the adjusters and loosen the counter nuts (3). Adjust both adjusters by the same amount: turn clockwise to increase free play and anticlockwise to reduce free play. When finished, tighten the counter nuts (3) and refit the rubber gaiters to the adjusters.
