EAU00794Steering inspection
Periodically inspect the condition
of the steering. Worn out or loose
steering bearings may be danger-
ous. Place a stand under the
engine to raise the front wheel off
the ground. Hold the lower end of
the front forks and try to move
them forward and backward. If any
free play can be felt, ask a Yamaha
dealer to inspect and adjust the
steering. Inspection is easier if the
front wheel is removed.

EAU00862Supporting the motorcycle
Since the Yamaha XV125S has no
centerstand, follow these precau-
tions when removing the front and
rear wheel or performing other
maintenance requiring the motor-
cycle to stand upright.
Front wheel service
To stabilize the rear of the motor-
cycle, either use a motorcycle
stand or place a motorcycle jack
under the frame in front of the rear
wheel to prevent it from moving
from side to side. Then use a
motorcycle stand to elevate the
front wheel off of the ground.Rear wheel service
Use a motorcycle stand or motor-
cycle jack to elevate the motorcycle
so the rear wheel is off the ground.
Alternatively, two jacks can be
placed under the frame or
swingarm.
Check that the motorcycle is in a
stable and level position before
starting any maintenance. A strong
wooden box can be placed under
the engine for added stability.

MOTORCYCLE CARE AND STORAGE
7-1
Care
The exposure of its technology
makes a motorcycle charming but
also vulnerable. Although high-
quality components are used, they
are not all rust-resistant. While a
rusty exhaust pipe may remain
unnoticed on a car, it does look
unattractive on a motorcycle.
Frequent and proper care, howev-
er, will keep your motorcycle look-
ing good, extend its life and main-
tain its performance. Moreover, the
warranty states that the vehicle
must be properly taken care of. For
all these reasons, it is recommend-
ed that you observe the following
cleaning and storing precautions.
Before cleaning
1. Cover up the muffler outlets
with plastic bags.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors,
including the spark plug caps,
are tightly installed.
3. Remove extremely stubborn
dirt, like oil burnt onto the
crankcase, with a degreasing
agent and a brush, but never
apply such products onto
seals, gaskets, sprockets, the
drive chain and wheel axles.
Always rinse the dirt and
degreaser off with water.Cleaning
After normal use
Remove dirt with warm water, a
neutral detergent and a soft clean
sponge, then rinse with plenty of
clean water. Use a tooth or bottle
brush for hard-to-reach parts.
Tougher dirt and insects will come
off more easily if the area is cov-
ered with a wet cloth for a few
minutes before cleaning.
ECA00010
cC
8Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If you do use
such products for hard-to-
remove dirt, do not leave it on
any longer than instructed,
then thoroughly rinse it off
with water, immediately dry
the area and apply a corrosion
protection spray.
