GENERAL SAFETY
Carbon monoxide
If you must run your engine, ensure the place is
well ventilated. Never run your engine in a
closed area. Run your engine in an open area, if
you have to run your engine in a closed area, be
sure to use an extractor.
Caution
Gasoline
Gasoline is a low ignition point and explosive
material. Work in a well-ventilated place, no
flame or spark should be allowed in the work
place or where gasoline is being stored.
Caution
Used engine oil
Caution
Hot components
Caution
Battery
Caution
Brake shoe
Do not use an air hose or a dry brush to clean
components of the brake system, use a vacuum
cleaner or the equivalent to avoid dust flying.
Caution
Brake fluid
Caution
Exhaust contains toxic gas which may cause
one to lose consciousness and even result in
death.
yBattery emits explosive gases; flame is
strictly prohibited. Keep the place well
ventilated when charging the battery.
yBattery contains sulfuric acid (electrolyte)
which can cause serious burns so be careful
do not be spray on your eyes or skin. If you
get battery acid on your skin, flush it off
immediately with water. If you get battery
acid in your eyes, flush it off immediately
with water, then go to hospital to see an
ophthalmologist.
yIf you swallow it by mistake, drink a lot of
water or milk, and take some laxative such
as castor oil or vegetable oil, and then go to
see a doctor.
yKeep electrolyte beyond reach of children.
Gasoline is highly flammable, and may explode
under some conditions, keep it away from
children.
Prolonged contact with used engine oil (or
transmission oil) may cause skin cancer
although it might not be verdict.
We recommend that you wash your hands
with soap and water right after contacting.
Keep the used oil beyond reach of children
Inhaling asbestos dust may cause disorders
and cancer of the breathing system.
Spilling brake fluid on painted, plastic, or rubber
parts may cause damage to the parts. Place a
clean towel on the above-mentioned parts for
protection when servicing the brake system.
Keep brake fluid beyond reach of children.
Components of the engine and exhaust
system can become extremely hot after
engine running. They remain very hot even
after the engine has been stopped for some
time. When performing service work on these
parts, wear insulated gloves and wait until
coolin
g
off.

SERVICE PRECAUTIONS
yAlways use with SANYANG genuine parts
and recommended oils. Using non-designed
parts for SANYANG motorcycle may damage
the motorcycle.
ySpecial tools are designed for remove and
install of components without damaging the
parts being worked on. Using wrong tools
may result in parts damaged.
yWhen servicing this motorcycle, use only
metric tools. Metric bolts, nuts, and screws
are not interchangeable with the English
system, using wrong tools and fasteners may
damage this vehicle.
yClean the outside of the parts or the cover
before removing it from the motorcycle.
Otherwise, dirt and deposit accumulated on
the part's surface may fall into the engine,
chassis, or brake system to cause a damage
yWash and clean parts with high ignition point
solvent, and blow dry with compressed air.
Pay special attention to O-rings or oil seals
because most cleaning agents have an
adverse effect on them.
zNever bend or twist a control cable to prevent
stiff control and premature worn out.
yRubber parts may become deteriorated when
old, and prone to be damaged by solvent and
oil. Check these parts before installation to
make sure that they are in good condition,
replace if necessary.
yWhen loosening a component which has
different sized fasteners, operate with a
diagonal pattern and work from inside out.
Loosen the small fasteners first. If the bigger
ones are loosen first, small fasteners may
receive too much stress.
yStore complex components such as
transmission parts in the proper assemble
order and tie them together with a wire for
ease of installation later.

1. GENERAL INFORMATION/TROUBLE DIAGNOSIS

yThe length of bolts and screws for
assemblies, cover plates or boxes is different
from one another, be sure they are correctly
installed. In case of confusion, Insert the bolt
into the hole to compare its length with other
bolts, if its length out side the hole is the
same with other bolts, it is a correct bolt.
Bolts for the same assembly should have the
same length.
yTighten assemblies with different dimension
fasteners as follows: Tighten all the fasteners
with fingers, then tighten the big ones with
special tool first diagonally from inside toward
outside, important components should be
tightened 2 to 3 times with appropriate
increments to avoid warp unless otherwise
indicated. Bolts and fasteners should be kept
clean and dry. Do not apply oil to the threads.
yWhen oil seal is installed, fill the groove with
grease, install the oil seal with the name of
the manufacturer facing outside, check the
shaft on which the oil seal is to be installed
for smoothness and for burrs that may
damage the oil seal.
yRemove residues of the old gasket or sealant
before reinstallation, grind with a grindstone if
the contact surface has any damage.
yThe ends of rubber hoses (for fuel, vacuum,
or coolant) should be pushed as far as they
can go to their connections so that there is
enough room below the enlarged ends for
tightening the clamps.
yRubber and plastic boots should be properly
reinstalled to the original correct positions as
designed.
yThe tool should be pressed against two (inner
and outer) bearing races when removing a
ball bearing. Damage may result if the tool is
pressed against only one race (either inner
race or outer race). In this case, the bearing
should be replaced. To avoid damaging the
bearing, use equal force on both races.
yLubricate the rotation as assembling. Check if
positions and operation for installed parts is
in correct and properly.
Cables and Harness Routing
Both of these examples can result in bearing damage.

Note the following when routing cables and wire
Harnesses:
zA loose wire, cable or harness may cause
safety hazard. After clamping, check each
wire to make sure it is secured.
zDo not squeeze wires against the weld or its
clamp.
zSecure wires and wire harnesses to the
frame with respective wire band at the
designated locations. Tighten the bands so
that only the insulated surfaces contact the
wires or wire harnesses.
zRoute harnesses so that they neither pull
too tight nor have excessive slack.
zProtect wires or wire harnesses with
electrical tape or tube if they contact a sharp
edge or corner.
zRoute wire harnesses to avoid sharp edges
or corners.
zAvoid the projected ends of bolts and
screws.
zKeep wire harnesses far away from the
exhaust pipes and other hot parts.
zBe sure grommets are seated in their
groves properly.
zAfter clamping, check each harness to be
certain that it is not interfered with any
moving or sliding parts.
zAfter routing .check that the wire harnesses
are not twisted or kink.
zWire harnesses routed along the handlebar
should not be pulled too tight or have
excessive slack, be rubbed against or
interfere with adjacent or surrounding parts
in all steering positions.
zThoroughly clean the surface where tape is
to be applied.
zWrap electrical tape around the damaged
parts or replace them.
