ADJUSTING THE CLUTCH
Adjust the clutch and if the engine stops or
tends to advance when the clutch lever is
pulled and the gears are engaged, or if the
clutch slips causing a delay in the acceler-
ation in comparison with the engine speed.
Minor adjustments can be carried out by
means of the adjuster (1):
◆
Withdraw the protection element (2).
◆
Loosen the nut (3) (by screwing it).
◆
Rotate the adjuster (1), until the idle
stroke at the end of the clutch lever is
about 10 mm (see figure).
◆
Tighten the nut (3) (by unscrewing it) and
lock the adjuster (1).
◆
Check the idle stroke at the end of the
clutch lever.
◆
Put back the protection element (2).
If the adjuster (1) is completely screwed or
unscrewed, or if it is not possible to obtain
the correct idle stroke:
◆
Withdraw the protection element (2).
◆
Tighten the nut (3) completely on the ad-
juster (1).
◆
Tighten the adjuster (1) completely.
◆
Unscrew and remove the plug (4) by
means of a cut-headed screwdriver (or a
coin).
The special spanner (5) is
available at any
aprilia
Official
Dealer .
◆
Insert the special spanner (5) and loosen
the inner nut (6).
◆
Insert a cut-headed screwdriver (7) in
the special spanner (5) and tighten the
adjusting screw (8) completely.
◆
Loosen the adjusting screw (8) by giving
it half a turn, which corresponds to 3÷4
mm of the lever (9) stroke.
◆
Keep the adjusting screw (8) locked by
means of the screwdriver (7), act on the
special spanner (5) and tighten the inner
nut (6).
◆
Tighten the plug (4) again.
◆
Check the idle stroke at the end of the
clutch lever (10 mm).
◆
Start the engine.
◆
Operate the clutch completely and and
engage the 1st gear. Make sure that the
engine does not stop, that the vehicle
does not tend to advance or that the
clutch does not slip during the accelera-
tion phase or while the vehicle is running.
If it is not possible to obtain a
correct adjustment or if the
clutch does not function proper-
ly, contact your
aprilia
Official Dealer .
Make sure that the clutch cable
is intact: it must not present flat-
tened parts and the sheath must not be
worn out in any point.
◆
Periodically lubricate the clutch cable
with a suitable lubricant, see p. 72 (LU-
BRICANT CHART), in order to avoid its
untimely wear and corrosion.
