DRIVE CHAIN SLACK INSPECTION AND ADJUSTMENT
3-35

NOTE:
If bleeing proves difficult, it may be necessary to
allow the brake fluid system to stabilise for a few
hours. Repeat the bleeding procedure when the
tiny bubbles in the system have disappeared.
j. Top up fluid to the maximum level.
DRIVE CHAIN SLACK INSPECTION AND
ADJUSTMENT
Inspecting slack:
NOTE:
Before checking and/or adjusting the chain, rotate
the rear wheel through several revolutions and
check the slack several times to find the point on
the wheel where chain slack is highest.
Check and/or adjust chain slack with rear wheel in
this “tight chain” position.
Drive chain slack:
30 ~ 40 mm
NOTE:
To check chain slack, the motorcycle must stand
in an upright position with its two wheels touching
the ground and no one sitting on it. Check slack in
the position shown in the figure.
2. Adjust:
•Drive chain slack
Slack adjustment:
Too little chain slack will overload the engine
and other vital parts. Keep the slack within the
specified limits.
CAUTION: 1. Check:
•Drive chain slack (a)
Out of specification ➔Adjust.

•Disconnect any hydraulic connection, other-
wise the whole system must be disassem-
bled, drained, cleaned, then properly filled
and bled after reassembly.
CAUTION:
NOTE:
It is unnecessary to disassemble the brake hose
to replace the pads.
NOTE:
•If you replace the pads, also replace the

rate, causing leakage and poor brake per-
formance.
•Refill with the same type of brake fluid:
mixing fluids may result in a harmful chem-
ical reaction and lead to poor perform-
ance.
•Be careful that water does not enter the
significantly lower the boiling point of the
fluid may result in vapor lock.
