If necessary, measure the oil level as follows.
Hold the inner tube vertically in a vise.
Pump the inner tube several times to expel air bubbles.
Using the piston rod puller [A], move the piston rod [B] up
and down more than ten times in order to expel all the air
from the fork oil.
Special Tool - Fork Piston Rod Puller, M12 × 1.25: 57001
Remove the piston rod puller.
Wait until the oil level settles.
With the fork fully compressed and the piston rod fully
pushed in, insert a tape measure or rod into the inner
tube, and measure the distance from the top of the outer
tube to the oil.
Oil Level (fully compressed, without spring)
101 ± 2 mm (3.98 ± 0.08 in)
(from the top of the outer tube)
Fork oil lever may also be measured using the fork oil
Special Tool - Fork Oil Level Gauge: 57001-1290 [A]
With the fork fully compressed and without fork spring,
insert the gauge tube into the inner tube [B] and position
the stopper across the top end [F] of the outer tube [C].
Set the gauge stopper [D] so that its lower side shows the
oil level distance specified [E].
Pull the handle slowly to pump out the excess oil until the
oil no longer comes out.
If no oil is pumped out, there is insufficient oil in the inner
tube. Pour in enough oil, then pump out the excess oil as
Screw the fork piston rod puller onto the end of the piston
Special Tool - Fork Piston Rod Puller,
Pull the puller up above the outer tube top.
Install the fork spring [A] with the smaller end facing [B]
