HYDRAULICALLY CONTROLLED CLUTCH
Bleeding the clutch system
A long travel and mushy feel of the clutch lever indicate that there is air in the
system and the clutch hydraulic system needs bleeding.
Bleeding procedure is as follows:
- Take the rubber cap off the bleed valve (1).
- Attach a clear plastic hose to the bleed valve and place the other end of the
hose in a vessel (make sure the hose end stays dipped in the uid throughout
the procedure).
- Remove the reservoir cover (2) and the rubber diaphragm (3) and ll fresh
uid into the reservoir. Use the uid specied in the lubricant table (see Sec-
tion A).
- Slacken the bleed valve and operate the lever (4) repeatedly until the uid
owing out of the hose looks clear and free of air bubbles: now tighten the
bleed valve.
- Top up uid level (A) and ret rubber diaphragm (3) and reservoir cover
(2).
Fluid level inside the reservoir shall never drop below the minimum
notch during the bleeding procedure.
Hydraulic uid is corrosive. In the event of contact with eyes, rinse
with abundant water.
Motorcycle handlebar must be turned to the right during the bleed-
ing procedure. This will keep the master cylinder reservoir higher,
making bleeding easier.
The bleeding procedure does not remove all air from the circuit; any
small amounts of air left in the circuit will disappear after a short
period of usage; this will eliminate the mushy feel of the lever and
restore its travel to proper length.
Bleed valve tightening torque: 12-16 Nm, 1.2-1.6 Kgm, 8.7-11.6 ft/
lb.
