+
The clutch system of this motorcycle is filled with a glycol-based brake fluid. Do not use or mix
different types of fluid such as silicone-based or petroleum-based. Do not use any brake fluid
taken from old, used or unsealed containers. Never re-use brake fluid left over from the last
servicing or stored for a long periods. Check the clutch hose and hose joints for cracks and fluid
leakage.
BLEEDING AIR FROM THE CLUTCH FLUID CIRCUIT
The clutch fluid circuit may be purged of air in the following man-
ner.
• Keep the motorcycle upright and place the handlebars straight.
• Fill up the master cylinder reservoir to the upper end of the
inspection window. Replace the reservoir cap to prevent entry
of dirt.
• Attach a pipe to the bleeder valve and insert the free end of
the pipe into a receptacle.
• Squeeze and release the clutch lever several times in rapid
succession, and squeeze the lever fully without releasing it.
Loosen the bleeder valve by turning it a quarter of a turn so
that the fluid runs into the receptacle; this will remove the ten-
sion of the clutch lever causing it to touch the handlebar grip.
Then, close the valve, pump and squeeze the lever, and open
the valve. Repeat this process until the fluid flowing into the
receptacle no longer contains air bubbles.
• Close the bleeder valve, and disconnect the pipe. Fill the res-
ervoir with brake fluid to the upper end of the inspection win-
dow.
