3. Check the air pressure in each fork
leg with an air pressure gauge.
NOTE:
An optional air pressure gauge is avail-
able at a Yamaha dealer.
4. To increase the spring rate and
thereby harden the suspension, in-
crease the air pressure with an air
pump or compressed air. To de-
crease the spring rate and thereby
soften the suspension, decrease
the air pressure by pushing each
valve stem down.
CAUTION:
ECA10090
Never exceed the maximum air pres-
sure, otherwise the front fork oil
seals may become damaged.
WARNING
EWA11180
There must be no difference in air
pressure between the left and right
fork legs, otherwise poor handling
and loss of stability may result.
5. Securely install the air valve caps.
