Service Manual JOKER 6
FORK ANGLE 1
system with spirit level
SERVICE MANUAL
WORK ON A FLAT EVEN SURFACE.
Whenever the seat height is changed or as periodic maintenance, check the fork angle and, if necessary, adjust it in order to have the fork
axis perpendicular to the ground.
The fork adjustment system is based on the combination of two rings (
A1, A2
) with inclined plane.
The upper ring
A1
works on the fork support while the ring
A2
works on the ring
A1
.

A1
Bearing unit detached from the fork support.
Pictures 1, 2 and 3 show that the upper axle of the bearing unit, rotating on
the lower axle (that allows the fork to turn), changes inclination thanks to the
inclined plane of the ring
A2
. Pictures 4, 5 and 6 show three different inclina-
tions of the ring
A1
keeping
A2
still. Each combination of the position of
these two rings gives a different angle to the fork axis.
To carry out the adjustment, start with loosening the nut
B
.
To do so, you have to align external hole
C
and the internal hole
C1
of the adjustment axle and insert a steel (or an Allen key) through them
(in the picture, the two parts are separate to make see the internal hole
C1
). With the pin inserted, you can turn the ring
A2
.
The nut
B
has to be loosened just enough to let the ring
A1
move.
Do not loosen the
B
too much, otherwise the system will be instable and it will be very difficult to
adjust.
The play should be null or the minimum possible.
To turn the ring’
A1,
insert a pin (or an Allen key) through the hole
D
.
Now, while keeping both pin inserted, turn ring
A2
(consequently the fork) without moving the ring
A1
.
While performing this operation check how the bubble of the spirit level
L
moves.
If, for the whole rotation of the ring
A2
. the bubble never passes through or close to the circle, it
means you need to change the position of ring
A1
.
