Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with an air valve for adjusting
the spring rate.
NOTICE
ECA11090
Never exceed the maximum air pres-
sure, otherwise the oil seal may be-
come damaged.
Adjust the spring rate as follows.
1.
Place the vehicle on the sidestand.
TIP
●
When checking and adjusting the
air pressure, there should be no
weight on the vehicle.
●
An air pump is required to adjust
the spring rate. This item is avail-
able at a Yamaha dealer.
2. Remove the shock absorber as-
sembly air valve cap.
3.
Check the air pressure with the air
pressure gauge included in the
owner’s tool kit.
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
and thereby soften the suspen-
sion, decrease the air pressure by
pushing the valve stem down.
5.
Securely install the air valve cap.
