Introduce the forks together with the drive
bushes on the gear tracks. To be precise; the
smaller fork
5
drives the sliding gear on the
primary unit, while the other two (
6
) drive
the sliding gears on the secondary unit.
Note:
the two forks
6
are interchangeable
and their positioning is univocal, since the
drive pin must face the desmodromic devi-
ce. If none of the components in question is
replaced, it is recommended to reposition
the forks in their original positions.
Insert the desmodromic device in the spe-
cific bearing. In order to do this, it is neces-
sary to rotate cam stop lever
7
towards the
bottom part of the engine.
Position the fork
5
of the primary unit in the
central guide of the desmodromic device
8
,
insert the fork pin inside the fork itself and
insert the pin in its proper seat in the cran-
kcase half.
