(contd.)

Note that turning the plate clockwise advances and anti-clockwise retards the timing. Also remember the importance of

the contact breaker gap, for even a slight variation tends to alter the timing. (Op ening the p oints adv ances
the timing ; closing them retards the timing).

A rough check of the timing can be made by observing the position of the hexagon nuts C in the slots in the contact

breaker plate. They s hould be approximately

6" to the left of the centre of the slots and it will be seen that

the timing can be roughly set by slackening off the hexagons, with the nearside p iston o n top d ead centre
o f th e compr ess ion stro ke, ens ur in g th at th ey are in th e app rox imate cen tr e of the slots and then re-
tightening after turning the contact breaker plate approximately -&" to the right.

Clutch.

Should it be necessary at any time to increase the spring

tension   on   the   clutch   pressure   plates,   access   to   the   spring   nuts   can   be
obtained through the primary drive oil level and  filler plug.  It  should,
however,   be   borne   in   mind   that   adjus tment   of   the   clutch
springs   should   only   be   necessary   after   a   very   considerable
mileage or if clutch slip   is   occurring,   and   before  any   alteration
to   the  spring   tension  is   made   ascertain   that  the   clutch   cable   is
correctly   adjusted,  as   in dicated   by   ap pro ximately   4"  of   free
movement at the end of the clutch handlebar lever, as in Fig. 22. The inner
cable  must  be  quite  free  and   not  binding  due  to  frayed   wire   or
other causes.

To adjus t the clutch springs take out the oil level

and filler plug and turn the engine gently until one of the three nuts can
be seen through the hole, then with a forked

screwdriver  screw   in   the   nut  very   s lightly   ;  say a quarter to half a turn. Revolve the engine again until another nut shows
and repeat the operation and again for the third nut, but great care must be  taken   to   ens ur e   that   each   nu t   is   adju sted
exactly  the  same amo un t,  o therw is e  th e p lates  w ill b e d isto rted  and  clutch  d rag  liab le  to  occu r.

Clutch slip can sometimes be detected by means of the kick-s tarter, for the s lip can be felt if the pedal

is depressed and the engine fails to turn over. It can also be detected when climbing hills under load by high
revving of the engine with loss of pulling power.

Because either clutch slip or clutch drag (failure to free the drive completely) is occurring, do not jump

to the conclusion that the clutch springs require adjustment. Instead make sure that the clutch cable itself is
quite free in the outer casing and that it is not damaged in any way.

Checking Oil Level in Primary Drive.

This is done by leaning the machine over slightly towards the left hand side, when, if the level is

correct, oil will start to run out of the filler plug hole. If the level is low then oil should be added up to the
bottom edge of the hole and the plug replaced. For the correct grade of oil refer to the oil recom mendation
chart in your instruction book.
