Diagnostics
Finding the problem Finding the possible cause Possible solutions proposed
Fork doesn't get full travel Oil level too high Check oil levels
Fork doesn't get full travel Spring rate too stiff Change to softer spring rate
Fork doesn't get full travel Spring rate too stiff Decrease air pressure
Fork extends too quickly; harsh top-out after
impacts
Rebound damping is not enough Increase rebound damping
Fork extends too quickly; harsh top-out after
impacts
Rebound damping is not enough
Replace the oil (SAE 7.5) with one of higher
viscosity index
Fork has too much sag Oil is too fluid Check oil levels
Fork has too much sag Spring rate too soft Change to stiffer spring rate
Fork has too much sag Spring rate too soft Increase air pressure
Fork has too much sag Spring rate too soft
Increase spring preload by replacing the preload
tube
Fork is “sticky”; fork does not perform as new
Dirty sealing rings; fork needs to be
serviced
Renew all seals
Fork is too soft, but the sag is the one
recommended
Compression damping is not enough
Increase compression damping by changing oil
volumes
Fork is too soft, needs more than the maximum
preload
Oil is too fluid Check oil levels
Fork is too soft, needs more than the maximum
preload
Spring rate too soft Change to stiffer spring rate
Fork is too soft, needs more than the maximum
preload
Spring rate too soft Increase air pressure
Fork stays down or "packs up" during multiple
impacts
Rebound damping is too high
Decrease rebound damping with the relevant
register
Front wheel tends to tuck under while turning left
or right
Rebound damping is too high
Decrease rebound damping with the relevant
register
Front wheel tends to tuck under while turning left
or right
Spring rate too soft Change to stiffer spring rate
Heavy amount of oil on stanchions; oil dripping
down legs
Sealing rings damaged Renew all seals
Heavy amount of oil on stanchions; oil dripping
down legs
The stanchion tubes could be damaged Have the stanchions be checked
Knocking sound during rebound, but no harsh top-
out
Rebound damping is too high
Decrease rebound damping with the relevant
register
Loss of sensitivity Old oil Change the oil
Loss of sensitivity Sliding bushes worn Renew the sliding bushes
Oil leaking from the bottom of the fork leg Bottom nut/screw loose Tighten the nut or screw
Oil ring on stanchions Sealing rings dirty Renew all seals
