jockey sprocket is mounted. Tightening of the
chain is effected by moving the quadrant to the
left.
It is imperative that the quadrant is fitted the
right way round and that the eccentric spindle is
fitted correctly in the quadrant fork. If the chain
tightens when the quadrant is moved to the right,
the tensioner has been wrongly assembled and
may cause damage to the quadrant (see Fig. 3).
In making the adjustment, care must be
taken to see that any backlash in the quadrant is
taken up in the "tightening" direction, i.e. do not
make the chain too tight and then move the
quadrant back slightly, but tighten the chain
progressively until the correct tension is
obtained and then lock the quadrant. If the chain
becomes too tight during adjustment, slacken it
right back and make the adjustment again.
If the chain is too slack it may give rise to a
loud noise which can be mistaken for a faulty
bearing. If it is too tight the result will be a high
pitched howl. If such noises are heard, therefore,
first check the adjustment of the timing chain.
7. Distributor Chain Adjustment
To adjust the distributor chain tension,
remove the timing cover (see Subsection 1),
slacken the three distributor fixing bolts, slide

the distributor back until the chain has about
3/16 in. up and down movement, then tighten
the fixing bolts.
8. Removal of Dual Seat and Rear Mudguard
Disconnect the leads to the rear lamp by
pulling out the plugs in the connectors near the
tool box.
Loosen the two nuts on either side of the seat
attaching the mudguard carrier to the frame and
lift the seat, mudguard and carrier off together.
9. Removal of the Petrol Tank
Turn off the petrol tap.
The petrol tank is attached to the frame by a
rubber mounted stud at the front, and is clipped
at the rear to a rubber sleeve surrounding the top
tube. To remove the tank, unscrew one front
attachment nut, tap out the stud and, after
disconnecting the petrol feed pipe, the rear of the
tank can be pulled upwards to release the clip
and then lifted clear of the frame.
10. Removal of the Cylinder Head
First remove the petrol tank and petrol pipe
(Subsection 9).
The dual seat may also be removed if desired
(Subsection 8).
Disconnect the head steady link. (Early
