STEERING DAMPER ADJUSTMENT
Change the fluid regularly. In new dampers after
10 hours riding and then every 20 hours riding.
Use only recommended fluid that is tested and ap-
proved by Yamaha. We cannot guarantee fully ac-
ceptable operation using other fluids.
NOTE:
Regular maintenance and inspection counteracts
possible malfunction.
If the steering damper needs service, Öhlins
agents have the proper tools and know-how to
solve all technical problems.
NOTE:
Discarded products should be handled over to an
authorized work shop or distributor for proper dis-
posal.
Trouble Shooting
Little or no damping
1 Debris in valving or worn parts internally, need
service.
2 Shear pin on bottom has broken due to a
crash or over stressing. This can be replaced
easily by removing the link-arm with a link-arm
puller and installing a new shear pin.
Dampens more to one side than the other
1 It´s new, give it a little time to seat the valving.
2 The oil is dirty and it need servicing.
Knob has come off
1 Don't panic, it will still work. To repair it,
remove the set screw, put the knob back on
and allow it to seat over the o-ring. Reinsert
the steel ball, then the spring and finally the
set screw until flush with the top of the knob.
