5UG1B001 Adjusting the front shock absorber
assemblies (YXR7FSPD)
WARNING
These shock absorber assemblies contain
highly pressurized nitrogen gas. Read and
understand the following information be-
fore handling the shock absorber assem-
blies.●
Do not tamper with or attempt to open
the cylinder assemblies.
●
Do not subject the shock absorber as-
semblies to an open flame or other
high heat source. This may cause the
unit to explode due to excessive gas
pressure.
●
Do not deform or damage the cylin-
ders in any way. Cylinder damage will
result in poor damping performance.
●
Do not dispose of a damaged or worn
out shock absorber assembly your-
self. Take the shock absorber assem-
bly to a Yamaha dealer for any
service.
The spring preload, rebound damping and
compression damping forces of the front
shock absorber assemblies can be adjusted
to suit the operating conditions. NOTICENever turn an adjusting mechanism be-
yond the minimum and maximum settings.

5. Install the bolts and tighten them to the specified torque. Valve clearance
The correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
