12.2 Use 'C spanner to adjust rear suspension units
must be renewed. This applies equally if the damper rod has
become bent. It is, however, possible to renew the springs
independently of the sealed damper units. Removal of the
spring however, does entail the use of some means of safely
compressing the spring so that the suspension unit top
mounting eye can be released.
6 To compress the spring, clamp the suspension unit at its
bottom mounting in a vice and enlist the aid of an assistant to
pull down the spring while the unit top mounting eye is
unscrewed. Note that a slim spanner can be passed between
the coils of the spring to slacken the locknut, while a bar is
passed through the mounting eye to provide the necessary
leverage for unscrewing it.
7 Examine the mounting bushes; if these are damaged or
worn they must be renewed. They can be removed and refitted
easily by pushing out both metal sleeves and rubber bushes as
separate items.
1 The centre stand shares a common pivot pin with the rear
brake pedal, the right-hand end of the pin being fitted with a
split pin. A strong return spring, attached to a small lug on the
right-hand side of the stand, retracts and holds the stand in
position when not in use.
2 Periodically the pivot pin should be lubricated with grease.
This is fairly important as its exposed position renders it
susceptible to corrosion if left unattended.
3 Be especially careful to check the condition and correct
location of the return spring. If this fails, the stand will fall onto
the road in use, and may unseat the rider if it catches in a drain
cover or similar obstacle.
14 Footrests: examination
1 The footrests form an assembly mounted below the engine
and can be detached as a complete unit. They are retained by
four bolts. The assembly is easily removed after the bolts have
been released. The complete unit must be manoeuvred to clear
the silencer. On refitting, tighten the bolts to a torque setting of
2.0 - 3.0 kgf m (14.5-22 Ibf ft).
2 Damage is likely only in the event of the machine being
dropped. Slight bending can be rectified by stripping the
assembly to the bare footrest bar, and straightening the bends
by clamping the bar in a vice. A blowlamp should be applied to
the affected area to avoid setting up stresses in the material,
which may lead to subsequent fracturing.
15 Rear brake pedal: examination and renovation
1 The rear brake pedal is mounted on a spindle, which is also
the pivot for the centre stand. It is retained, together with its
return spring, by a circlip on the right-hand side of the machine.
2 Should the pedal become bent in an accident, it can be
straightened in a similar manner to that given for footrests in
the preceding Section. If severely distorted, it should be
renewed.
