CHECKING THE TIRES
1. Measure:
• Tire pressure
Out of specification Regulate.
TIP
• Check the tire while it is cold.
• Loose bead stoppers allow the tire to slip off
its position on the rim when the tire pressure
is low.
• If the tire valve stem is found tilted, the tire is
considered to be slipping off its position. Cor
-
rect the tire position.
EAS1SL1108CHECKING AND TIGHTENING THE
SPOKES
1. Check:
• Spokes
Bend/damage Replace.
Loose Tighten.
TIP
A tight spoke will emit a clear, ringing tone; a
loose spoke will sound flat.
Direction “a”
Low compression damping force is in-
creased (suspension is harder).
Direction “b”
Low compression damping force is de-
creased (suspension is softer).

Maximum
Turn it in finger-tight.
STD
Turn it out by 12 clicks.*
(USA)(CAN)
Turn it out by 10 clicks.*
(EUR)(JPN)(AUS)(NZL)(ZAF)
Minimum
Turn it out by 20 clicks.*

EAS1SL1123REMOVING THE FRONT WHEEL
1. Use a suitable stand to raise the front wheel
off the ground.
EWA13120
WARNING
Securely support the vehicle so that there is
no danger of it falling over.
2. Remove:
• Front wheel
EAS1SL1124CHECKING THE FRONT WHEEL
1. Check:
• Front wheel axle
Roll the front wheel axle on a flat surface.
Bends Replace.
EWA13460
WARNING
Do not use a bent front wheel axle even after
correcting this.
2. Check:
•Tire (s)
• Front wheel
Damage/wear Replace
Refer to “CHECKING THE TIRES” on page
3-32 and “CHECKING THE WHEELS” on
page 3-33.
3. Check:
• Spokes
Bend/damage Replace.
Loose Tighten.
Tap the spokes with a screwdriver.
TIP
A tight spoke will emit a clear, ringing tone; a
loose spoke will sound flat.
4. Tighten:
• Spokes
Refer to “CHECKING AND TIGHTENING
THE SPOKES” on page 3-32.
TIP
After tightening the spokes, measure the wheel
runout.
5. Measure:
• Wheel radial runout “a”
• Wheel lateral runout “b”
Out of specification Repair/replace.
6. Check:
•Collars
Damage/wear Replace
7. Check:
• Bearing
Front wheel turns roughly or is loose Re-
place the wheel bearings.
• Oil seals

TIRE PRESSURE
Tire pressure should be adjusted to suit the
road surface condition of the circuit.
• Under a rainy, a muddy, a sandy, or a slippery
condition, the tire pressure should be lower
for a larger area of contact with the road sur
-
face.
• Under a stony or a hard road condition, the
tire pressure should be higher to prevent a flat
tire.
EAS1SL1369FRONT FORK SETTING
The front fork setting should be made depend-
ing on the rider's feeling of an actual run and
the circuit conditions.
The front fork setting includes the following
three factors:
1. Setting of air spring characteristics
• Change the fork oil amount.
2. Setting of spring preload
• Change the spring.
3. Setting of damping force
• Change the compression damping force.
• Change the rebound damping force.
The spring acts on the load and the damping
force acts on the cushion travel speed.
EAS1SL1370CHANGE IN AMOUNT AND CHARACTERIS-
TICS OF FORK OIL
Damping characteristic near the final stroke
can be changed by changing the fork oil
amount.
EWA1DX4001
WARNING
Adjust the oil amount in 5 cm3 (0.2 US oz,
0.2 Imp. oz) increments or decrements. Too
small oil amount causes the front fork to
produce a noise at full rebound or the rider
to feel some pressure on his hands or body.
Alternatively, too large oil amount will
cause the air spring characteristics to have
a tendency to be stiffer with the consequent
deteriorated performance and characteris
-
tics. Therefore, adjust the front fork within
the specified range.
