POSITIONING OF STOP CAM ON DESMODROMIC
DEVICE
1) Stop lever;
2) Stop cam;
3) Screw M6x30;
4) Movable pawl return spring.
3.8.2 ASSEMBLY OF EXTERNAL GE-
ARSHIFT
Keeping the stop lever moved
1
in such a way that
the spring is compressed, position the stop cam
2
on the protruding end of the desmodromic ge-
arshift (external right crankcase). The stop cam has
only one correct position which is determined by
the particular shape of the end of the desmodromic
device and of the bottom part of the stop cam.
Proceed mounting the tightening screw
3
M6x30
between the stop cam and the desmodromic ge-
arshift, after having applied medium-resistance se-
alant: tighten it at 10Nm.
Insert the drive shaft together with the washer in
its seat keeping the return spring
4
of the movable
pawl pressed.
Wishing to test the correct functioning of the entire
unit, you just need to temporarily couple the exter-
nal gearshift lever and to simulate the operation of
changing gears, by lifting and lowering the gearshift
lever and having the mainshaft of the gear unit ro-
tate. The whole device works properly if abnormal
jamming does not occur.
If the unit runs without oil, the device makes more
noise than usual.
3.9
KICK StARtER
Before coupling the kickstarter to the crankcase
half, some controls must be carried out.
3.9.1 CHECKING KICKSTARTER
SHAFT UNIT AND ASSEMBLY
In order to disassemble all the parts of the kickstart
shaft, pull off the washer
11
at the end of the shaft
(on the side of the spring
16
), the spring
16
, the
kickstart sleeve
14
, and the lever return spring
8
,
which to be unfastened from the shaft must be pul-
led in the radial direction so that it is extracted from
its hole. Pull out the kickstart spacer
