SERVICE INFORMATION
GENERAL
• When servicing the front wheel, fork or steering stem, support the motorcycle using a safety stand or hoist.
• A contaminated brake disc or pad reduces stopping power. Discard contaminated pads and clean a contaminated disc with a
high quality brake degreasing agent.
• After the front wheel installation, check the brake operation by applying the brake lever.
• For brake system information (page 15-4).
• Use only tires marked "TUBELESS" and tubeless valves on rim marked "TUBELESS TIRE APPLICATION".

Axle
Set the axle [1] on V-blocks and measure the runout.
Actual runout is 1/2 the total indicator reading.
[1]
SERVICE LIMIT: 0.2 mm (0.01 in)
Wheel bearing
Turn the inner race of each bearing [1] with your finger.
The bearings should turn smoothly and quietly.
Also check that the outer race of the bearing fits tightly
in the hub.
Replace the
bearings in pairs.
Replace the bearing if the inner race does not turn
smoothly, quietly, or if the outer race fit loosely in the
hub.
Replace the wheel bearings, if necessary (page 13-14).
[1]
Wheel rim runout
Check the rim runout by placing the wheel in a truing
stand.
Spin the wheel by hand, and read the runout using a
dial indicator.
Actual runout is 1/2 the total indicator reading.

FRONT WHEEL/SUSPENSION/STEERING
Wheel balance
• Wheel balance directly affects the stability, handling
and overall safety of the motorcycle. Always check
balance whenever the tire has been removed from
the rim.
• For optimum balance, the tire balance mark [1] (a
paint dot on the side wall) must be located next to
the valve stem [2]. Remount the tire if necessary.
[1]
[2]
Note the rotating direction marks [1] on the tire, and
upon tire installation, always fit the tire so the marks
face the same direction.
[1]
Remove the dust seals from the wheel.
Mount the wheel, tire and brake discs (and pulser ring:
(CBF1000FA/FT/FS) assembly in an inspection stand
[1].
Spin the wheel, allow it to stop, and mark the lowest
(heaviest) point of the wheel with a chalk.
Do this two or three times to verify the heaviest area.
If the wheel is balanced, it will not stop consistently in
the same position.
To balance the wheel, install the wheel weights on the
highest side of the rim, the side opposite the chalk
marks. Add just enough weight so the wheel will no
longer stop in the same position when it is spun. Do not
add more than 60 grams to the wheel.
