Nicks or rust damage can sometimes be repaired by using a wet-stone to remove sharp edges or raised areas which cause seal damage.
★ If the damage is not repairable, replace the inner tube. Since damage to the inner tube damages the oil seal, replace the oil seal whenever the inner tube is repaired or replaced.
Caution! If the inner tube is badly bent or creased, replace it. Excessive bending, followed by subsequent straightening, can weaken the inner tube.
Temporarily assemble the inner and outer tubes, and pump them back and forth manually to check for smooth operation.
If you feel binding or catching, the inner and outer tubes must be replaced.
Warning! A straightened inner or outer fork tube may fall in use, possibly causing an accident. Replace a badly bent or damaged inner or outer tube and inspect the other tube carefully before reusing it.
Dust seal inspection
Inspect the dust seal [A] for any signs of deterioration or damage.
★ Replace it if necessary.

Spring tension
Since a spring becomes shorter as it weakens, check its free length [A] to determine its condition.

★ If the spring of either fork leg is shorter than the service limit, it must be replaced. If the length of a replacement spring and that of the remaining spring vary greatly, the remaining spring should also be replaced in order to keep the fork legs balanced for motorcycle stability.
Fork spring free length:
- Standard: 527.2 mm (20.76 in.)
- Service Limit: 517 mm (20.4 in.)
