1. Support the bike with the front wheel offthe
2. Remove the air valve caps (Figure 32).
3. Connect a pump to the valve and pump the
forks up to about 25 psi.
Do rlot e x r e d 36 psi, or the-fork seals
will be damaged.
4. Slowly bleed off the pressure to reach the
desired value. Refer to Table 4 for standard air
pressure and recommended range. Kawasaki
recommends balancing light fork air pressure
with light rear shock preload and damping and
heavy fork air pressure with heavy rear shock
preload and damping.

5. Install the valve caps and rubber covers.
Apply the front brake and pump the forks up
and down hard. You should hear the fork oil as
it flows through its passages and there should
bc no binding. Inspect for fork oil leakage
around the fork seals. If there is evidence of
leakage, check the fork oil level; see

oil without removing the forks from the

disassembled as described in Chapter Seven,
more of the old oil will be drained.

2. Place a drain pan under the fork and remove
the drain bolt (Figure 33). Let the oil drain for
a few minutes, then pump the fork (keeping
your hand on the brake lever) to help expel the
oil. Install the drain screw and repeat for the
other fork leg.
