Adjusting The Shock Absorber Assembly - Yamaha Royal Star Venture XVZ13TFX Owner's Manual

INSTRUMENT AND CONTROL FUNCTIONS
3. Check the air pressure in each fork
leg using a low-pressure air
gauge. A low-pressure air gauge is
available at a Yamaha dealer.
4. To increase the spring rate and
thereby harden the suspension, in-
crease the air pressure with an air
pump. To decrease the spring rate
3
and thereby soften the suspen-
sion, decrease the air pressure by
pushing each valve stem down.
Spring rate:
Minimum (soft):
Air pressure = 0 kPa (0 psi) (0
kgf/cm²)
Standard:
Air pressure = 0 kPa (0 psi) (0
kgf/cm²)
Maximum (hard):
Air pressure = 50 kPa (7.1 psi) (0.5
kgf/cm²)
CAUTION:
Never exceed the maximum air pres-
sure, otherwise the front fork oil
seals may become damaged.
5. Securely install the air valve caps.
Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with an air valve for adjusting
the spring rate.
CAUTION:
Never attempt to turn an adjusting
mechanism beyond the maximum or
minimum settings.
Adjust the spring rate as follows.
1. Place the vehicle on the sidestand.
NOTE:
When checking and adjusting the air
pressure, there should be no weight on
the vehicle.
2. Remove the air valve cap.
