8.  Repairs 

In  the  event  of  damage  to  the  fairing,  small 

repair  kits  consisting  of  a  quantity  of  resin, 
catalyst  and  glass  fibre  are  available  from  our 
Service  Department.  Instructions  for  carrying 
out minor repairs are issued with this kit. 

 

9.  Reassembly of the 
Fairing 

If  these  have  been  removed  replace  the  two 

bottom  fairing  attachment  studs,  also  fit  the 
rubber  sleeve  to  the  down  tube.  Next  raise  the 
fairing  over  the  fork  cover  tubes,  locating  the 
bottom  attachment  plates  on  each  leg  shield 
over the attachment studs. 

Incline  the  fairing  outwards  and  thread  the 

light  and  switch  leads  through  the  strut  tube 
aperture, and the speedometer cable through the 
smaller  hole  below  it.  The  fairing  can  then  be 
pushed  towards  the  forks  until  the  strut  tube, 
complete  with  buffer  assembly,  has  entered  the 
aperture and is positioned between the strut tube 
attachment plates. Fit the stud through the buffer 
assembly  and  attachment  plates  and  secure 
washers and nuts to either end. 

Complete  the  fairing  assembly  to  the 

machine  by  fixing  the  attachment  cap  over  the 
attachment  stud  rubber.  Compress  these  parts 
together  and  secure  with  the  attachment  clip. 
The exhaust system may now be fitted. 

 

10

Reassembly of Mudguard, Fork Legs 

and Wheel 

Fit the two sealing washers to the fork cover 

tubes, not forgetting the small sealing washer for 
the fork crown extension tube on Early Models. 
Raise the mudguard, and thread the cover tubes 
(and  the  fork  crown  extension  when  fitted) 
through  their  respective  holes.  Line  up  the 
mudguard bracket holes with the fork crown clip 
bolt  holes  and  fit  the  bolts,  washers  and  nuts 
finger tight. (On Early Models fit the fork crown 
extension stud and washer.) 

Slide  the  fork  legs  up  into  the  fork  head. 

Centralise  the  fork  leg  top  with  the  cover  tube, 
and push up to the full extent. Fit and tighten the 
plug screws in the fork head. 

The  fork  crown  clip  bolts  may  now  be 

tightened. 

Replace  the  wheel  and  connect  up  the  brake 

cable  at  both  ends. 

Do  not  forget  to  readjust 

the brake. 

 

11.

 

Reassembly of Headlamp 

Thread  the  red  earth  wire,  the  blue  and  red, 

and the blue and white main bulb wires from the 
dipper switch, and one green and brown pilot 

lamp  wire,  through  the  hole  in  the  lamp  body 
shell.  Fit  the  body  shell  rubber  washer  between 
the fairing and the lamp body shell rim, and line 
up the holes in the shell rim, the washer and the 
fairing aperture rim. Secure with the four screws 
and locking plates, keeping the threaded plate at 
the bottom. 

Connect  the  blue  and  red  and  the  blue  and 

white wires to the main bulb wires in the back of 
the  light  unit.  Push  the  green  and  brown  lead 
into  the  pilot  lamp  socket  and  the  single  red 
earth wire from the main harness into the socket 
on the main bulb fitting. 

The  light  unit  may  now  be  pushed  over  the 

three adjusters, after first slackening them. Turn 
the light unit in a clockwise direction to secure. 
Afterwards  tighten  all  the  adjusters  as  far  as 
possible. 

Place the rubber ring over the light unit, with 

the  face  marked  "BACK"  facing  the  light  unit 
rim. Locate the spigot plate, situated on the top 
underside  of  the  rim,  with  the  slot  in  the  lamp 
body shell. Press the rim downwards and screw 
in the pin at the bottom of the rim. 

Finally,  adjust  the  aim  of  the  light  beam  by 

turning  the  adjuster  screws  in  a  clockwise 
direction  from  the  rear  as  neccessary.  Do  not 
turn  them  further  than  required,  not  more  than 
two screws will need adjusting. 

 
 

12.  Reassemble  of  Ammeter,  Headlamp 

Switch and Speedometer 

Insert  the  ammeter  into  the  off-side  hole  in 

the  fairing,  turn  up  under  the  fairing  the  small 
tabs  on  the  ammeter,  and  fit  the  rubber  ring, 
pushing it up as far as possible. Connect up the 
two wires with the tab washer type connections 
to the ammeter terminals. 

Push the switch up from the underside of the 

fairing,  place  in  position  the  switch  plate  and 
secure  with  the  nut.  Finally,  put  on  the  small 
washer and the switch knob, and secure with the 
screw. 

Push  the  speedometer  into  the  fairing  from 

above,  and  secure  the  bracket  with  the  nuts  and 
washers  from  below.  Fit  the  speedometer  drive 
and lamp. 
 
 

13.  Reassembly of Windscreen 

Put  the  female  screws,  with  their  plain  steel 

and  rubber  washers,  into  the  back  plate  and 
windscreen,  and  line  up  with  the  holes  in  the 
fairing.  Be  sure  to  use  the  shortest  male  screw 
for  the  centre  countersunk  hole,  and  the  two 
longest for attaching the number plate.
