Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
1. Place a stand under the engine to
raise the front wheel off the
ground. (See page 7-36 for more
information.) WARNING! To avoid
injury, securely support the vehi-
cle so there is no danger of it
falling over.
2. Hold the lower ends of the front
fork legs and try to move them for-
ward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the steering.EAU23290
Checking the wheel bearings
The front and rear wheel bearings
must be checked at the intervals spec-
ified in the periodic maintenance and
lubrication chart. If there is play in the

lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
