Honda CG125 (1976-1991) [12/128] Check the suspension and steering

Routine maintenance

and close the throttle several times, allowing it to snap shut

under its own pressure. Ensure that it is able to shut off quickly

and fully at all handlebar positions, then check that there is 2 —

6 mm (0.08 - 0.24 in) of cable free play, measured in terms of

twistgrip rotation. If adjustment is necessary, use first the

adjuster which is set below the twistgrip. If there is an

insufficient range of adjustment the surplus free play can be

eliminated by peeling back the rubber cover and by using the

adjuster on the carburettor top.

7 Check the clutch adjustment

Fine adjustment is provided on the handlebar lever by way

of a threaded adjuster and lockring. Should this prove

insufficient, a second adjuster nut and locknut can be found at

the cable lower end. These should be set to give 10-20 mm

(0.4 — 0.8 in) movement at the lever end before the clutch

begins to lift.

8 Check the brakes

The brakes are adjusted by a nut at the end of the brake

cable or rod, as appropriate, with the front brake having an

additional fine adjuster at the cable handlebar end. To adjust the

brakes place the machine on its centre stand with the wheel to

be adjusted clear of the ground. Spin the wheel and tighten the

adjusting nut until a rubbing sound is heard as the shoes begin

to contact the drum, then unscrew the nut by

- 1 turn until

the sound ceases. Spin the wheel hard and apply the brake

firmly to settle all components, then re-check the setting. This

procedure should give the specified setting of 20

30 mm (0.8

1.2

in) free play, measured at the lever or pedal tip. Check that

the stop lamp rear switch is set so that the lamp lights just as

pedal free play is taken up and the brake is beginning to engage.

At regular intervals the wheels should be removed so that

each brake assembly can be cleaned and checked for wear.

Renew any worn components and apply a smear of grease to

the camshaft bearing surfaces on reassembly. See Chapter 5.4.

9 Check the wheels

Referring to Chapter 5.2 check the wheel rims for runout,

the spokes for straightness, security and even tension, and the

bearings for signs of free play. Any faults found must be

rectified immediately.

Check the suspension and steering

Support the machine so that it is secure with the front

wheel clear of the ground, then grasp the front fork legs near

the wheel spindle and push and pull firmly in a fore and aft

direction. If play is evident between the top and bottom fork

yokes and the steering head, the steering head bearings are in

need of adjustment. Imprecise handling or a tendency for the

front forks to judder may be caused by this fault.

Bearing adjustment is correct when the lockring is

tightened until resistance to movement is felt and then

loosened by

of a turn. The lockring should be rotated by

means of a C-spanner after slackening the steering stem nut.

Take great care not to overtighten the lockring. It is possible

to place a pressure of several tons on the head bearings by

over-tightening even though the handlebars may seem to turn

quite freely. Overtight bearings will cause the machine to roll at

low speeds and give imprecise steering. Adjustment is correct if

there is no play in the bearings and the handlebars swing to full

lock either side when the machine is supported with the front

wheel clear of the ground. Only a light tap on each end should

cause the handlebars to swing. Secure the

lockring

tightening the steering stem nut to a torque setting of 6.0 - 9.0

kgf

(43

Ibf

ft) then check that the setting has not altered.

Examine closely the front and rear suspension. Ensure that

the front forks work smoothly and progressively by pumping

them up and down whilst the front brake is held on. Any faults

revealed by this check should be investigated further. Check

carefully for signs of leaks around the front fork oil seals. If any

damage is found, it must be repaired immediately as described

in the relevant Sections of Chapter 4.

To check the swinging arm place the machine on its centre

stand then pull and push horizontally at the rear end of the

swinging arm; there should be no discernible play at the pivot.

Repeat all service operations listed under previous

headings, then carry out the following:

The spark plug should be renewed at this interval,

regardless of its apparent condition.
