TROUBLE SHOOTING

Stiff steering:

Steering bearing adjusting ring nut too tight.
Faulty steering sleeve bearings.
Tyre pressure too low.

Motorcycle tends to steer to one side and has poor handling:

Bent front fork.
Bent front wheel spindle.
Wheel not fitted correctly.
Unlike quality of oil in the fork legs.

Motorcycle oscillations and vibrations:

Deformed rim.
Loose or worn wheel bearings.
Defective tyre.
Wrong tyre pressure.
Slack and/or deformed spokes.
Slack wheel spindle.
Incorrect wheel balancing.

Suspension too soft:

Insufficient quantity fork oil.
Fork oil too fluid.
Weakened fork springs.

Suspension too stiff:

Too much quantity fork oil.
Fork oil too dense.
Damaged legs or stanchions.

Noisy front suspension:

Blocked fork legs.
Poor quantity of fork oil.
Loose front fork bolt.

Poor braking performance:

Missing or poor quantity of brake fluid.
