Adjusting headstock angle (fig. 33.1)
Loosen the two screws (1) on the frame r.h. side to
adjust the headstock angle.
Fully unscrew the screw (2) and turn the steering tube
end (3) by 180° with a pin wrench.
Check that the hole on the eccentric is centred with the
through hole in the steering tube. Look at the arrow
etched in the top area of the eccentric to centre both
holes accurately.
Fully screw the screw (2). Grease the screw threadings
(1) with SHELL Retinax HDX2 and tighten to 22 Nm.
Note
While performing the above, the handlebars should
not be fully turned.
When finished, the steering damper must be
repositioned. Undo the screw (4, fig. 33.2). Move the
damper rod joint to the frame hole (5). Tighten the screw
(4) previously removed and apply some medium-strentgh
threadlocker.
Important
The steering lock can be used only if the steering
tube is positioned at 24°30'. This adjustment is possible
for 748S and 998 models only.
