Bold reference numbers in this section identify parts shown in this exploded view diagram. These parts do not appear in the figures near the text.

Adjusting the throttle and choke cables

Read Sect. D 4, Adjusting the throttle and choke cables, for relevant instructions.

Disassembling the throttle control

Rotate the throttle control pulley until releasing the cable nipple (D) from the pulley.

Slip off the rubber gaiter (A), slacken the lock nut and turn out the adjuster (10) until it slides off the throttle control pulley on the throttle body.

Release and remove the screws (4) and take off the cover (13). Withdraw the cable nipple (E) from the pulley and turn out the adjuster (8) until it slides out so as to disconnect the throttle cable from the throttle control.

Remove the throttle cable (6) from the motorcycle.

Remove the plug (9) on the handlebar.

Loosen the two screws (3) securing the throttle control to the handlebar.

Remove the throttle control (5) from the handlebar.

Disturbing the throttle cable may affect the throttle body adjustments. Before refitting throttle control cable read Sect. D 5, Zero setting the throttle position sensor (TPS).

Reassembling the throttle control

To refit, reverse the removal procedure.

Smear the throttle cable (6) with the specified grease.

Refer to the figures on the next pages for the correct routing of the throttle cable.

Removing the choke control

Slacken the retaining screw (F) of the choke cable.

Slip off the rubber gaiter (C), slacken the check nut and turn out the adjuster (11) until it comes off the bracket.

Withdraw the choke control (2) and collect the spring (7).

Loosen screws (V) and remove the left-hand switch (14) together with choke control from the handlebar.

Open the switch and remove the stop pin (G).

Remove the complete choke control (2).

Disturbing the choke cable may affect the throttle body adjustments. Before refitting choke control cable read Sect. D 5, Zero setting the throttle position sensor (TPS).

Refitting the choke control

The spare choke cable is supplied together with adjusters and drive cable.

Grease the choke cable (2).

Fit the choke cable (2) in the left-hand switch and fit the stop pin (G) into its seat.

Fix the left-hand switch (14) to the handlebar and tighten the screws (V) to the specified torque (Sect. C 3, Frame torque settings).

Check that the choke control lever is in the rest position.

Insert the new control cable (2) in the frame. Observe the original routing.

Tighten the adjuster (11) into the throttle body support.

Thread the core cable (2) through the linkage hole, the spring (7) and the throttle body pawl.

Pull the end of the core cable to keep the cable taut and tighten the pawl screw (F).

Loosen the check nut and work the adjuster (11) so as to allow some play in the sheath.

Rotate the lever fully down and make sure that the small lever (H) of the throttle body contacts the end stop (L). If not so, slacken the screw (F) and release the core cable (2).

Repeat the process until the small lever (H) is touching the end stop (L).

Turn the handlebar right and left and make sure the small lever (H) is not moving. Otherwise, turn the adjuster (11).

Tighten the check nut into the adjuster (11) when finished.

Refer to the figures on the next pages for the correct routing of the choke cable.
