Adjusting the throttle and choke cables
Read Adjusting the throttle and choke cables for instructions on throttle and choke cable adjustments.
Removal of the throttle twistgrip
Rotate the race on the throttle body linkage to free the end (D) of the inner cable from the race.
Peel back the rubber sleeve (A), unscrew the lock nut (B) and unscrew the adjuster (10) from the race on the throttle body.
Remove the screws (4) and the cover (13) and disconnect the throttle cable from the twistgrip, freeing the cable end (C) from the race and fully unscrewing and removing the adjuster (8).
Remove the throttle cable (6) from the motorcycle.
Remove the end plug (9) from the handlebar.
Loosen the two screws (3) fixing the throttle twistgrip to handlebar.
Remove the throttle twistgrip (5) from the handlebar.
Refitting the throttle twistgrip
To refit the throttle control components, proceed in inverse order to the removal procedure, making sure that the twistgrip housings locate in the reference hole in the handlebar.
Apply the recommended grease to the throttle cable (6).
Note: Refer to the figures at the end of the chapter for the correct routing of the starter control cable.
Removal of the choke cable
Unscrew the choke cable retaining screw (E).
Peel back the rubber sleeve (F), loosen the lock nut (G) and screw the adjuster (11) completely out of the bracket.
Withdraw the choke cable (2) from the throttle body and recover the spring (7).
Remove the left-hand handlebar switch (14) with the choke control by unscrewing the screws (H).
Open the handlebar switch housing and withdraw the end fitting (L) of the choke inner cable from the switch.
Remove the choke control cable (2).
Refitting the choke control
Note: The choke control is supplied as a replacement part complete with the adjusters and cable.
Lubricate the choke cable (2).
Insert the choke cable (2) in the left-hand handlebar switch and locate the inner cable end fitting (L) in its notch.
Refit the left-hand switch (14) to the handlebar and tighten the screws (H) to the specified torque (Frame torque settings).
Check that the choke lever is in its rest position.
Position the new cable (2) along the frame following the route of the original cable.
Tighten the adjuster (11) on throttle body support.
Insert the inner cable (2) in the hole of the rocker, in spring (7) and in the throttle body linkage.
Pull the end of the inner cable to keep the cable taut and tighten the screw (E).
Loosen the lock nut and turn the adjuster (11) to obtain a little freeplay of the outer cable.
Rotate the lever fully downwards and make sure that throttle body lever (M) locates against the stop (N). If not, loosen the screw (E) and release the inner cable (2).
Repeat the procedure until the lever (M) touches the stop (N).
Turn the handlebar fully to the right and left and make sure lever (M) does not move. If it does, loosen the adjuster screw (11).
Once the correct adjustment is obtained, tighten the lock nut against the adjuster (11).
Note: Refer to the figures on the next page for correct routing of the choke cable.
