machine oil before drive by sup-porting
i t with the
Main stand on a flat ground.The oil
livel should be between the upper and
lower
Lines of the oil gauge. Which is not
screwed into the filling orifice.
★ High quality 4-stroke machine
oil. Class SE or SD in API classif i-
cation.of SAE15W-40 in viscosity will
help maintain a long service life or the
engine.In case those are not available,a
substitute suitable for the ambient
temperature of application should be
selected according to the table on the

Oil
Machine oil plays a very important
role in the normal operation of the
engine and for this reason,it is necessary
to check the motorcycle for machine oil
periodically and renew the oil once
every800-1,000k m of driving by the
follow ing procedures.
Remove the screw plug from the
bottom of the hot engine to drain off all
old oil.
Wash the oil filter screen clean and
remount it really to positi on.Then fill in
0.8L fresh machine oil and start the
engine for idle running2-3 minutes.
Let the engine stop for 1-2
minutes and check to see whether the
oil level is in between the upper and
l ower lines of the oil gauge.
Do not use any machine oil of a
different grade than the specif ied one
toavoid machinery failure.

3.Wash clean all the related parts.
4.Fill in the required oil.
＊ This job should not be done by untrained
persons but shall be done at an authorized service
center. 1.Remove the cap of spark plug and screw off
the spark plug by the plug wrench.
2.Clean the spark plug all aroud or replace it
if i t is corroded or there is too much deposit on it.
3.Regulate the gap of the spark plug to 0.6-
0.7mm.
4.The spark plug of the designated type should
be used. The applicable type of spark plug: NHSP
LD D8TC made i n China.
14
Check-up & Cleaning ofAir Filter
Take out the air filter and check if it is
contaminated.
Dismounting:
Remove the right side cover,take out the screw
and disassemble the air filter.
Cleaning:
Wash the filter i n cl ean washing oil and wipe it
dry with dry cloth.
Soak it in clean machine oil,squeeze it dry and fit
it back to position.
Recommended oil:15W/40QE
Caution:
The air filter element for use must be intact or the
enine will suck in dust and dirt, resulting in a shorter
service life of the engine.
Water should be prevented from entering into the
filter in washing the vehicle.
The filter shall neve

AdjustmentofThrottle Cable
Make sure that the adjusting nut of the throttle
cable and l ocking nut work normally.
Check to see if the throttle twist grip is with the
required free operating movement.
Therequired free operating movement:2-6mm.
If the grip can not be so moved freely.turn the
adjust ing nut to ensure it.
After adjustment, start the engine and check for
the free operating movenent again,Repeat the
adjustment if necessary until it is as required.
AdjustmentofCarburetor
Caution:
The adjusting procedures of idling speed:
1.Support the vehicle by a stand.
2.Adjust the idling speed by the throttle stop
screw(1) to 1500±150rpm.
Caution:
Do not try to cover up any trouble of other parts of the
carburetor by adjust ing the idling speed. In case of
any abnormality wi th the carburetor,it has to removed
by your dealer.
Adjust ment of idling speed shall be made only when
the cold engine is warmed up or 10 minutes after the
motorcycle is stopped from driving.
16
Check-up & AdjustmentofAir ValveGap
Noise will stem from too big gap of the air valve. However if there is too small gap or even no gap at all,
closing of the valve will be hindered, which will cause burn of the valve and output drop. Therefore, the air valve gap
must be checkedperiod ically.
The gap of the air valve should be inspected and adjusted with a cold engine by the following procedures:
1.Remove the capsof the central hole and the top hole (the ignition timing observation hole)in the left crankcase
cover.
2.Remove the capsof the two air valves on the cylinder head.
3.Insert the “T” key into the central hole of the crankcase cover, jam it against the nut of the flying wheel and
then turm the flying wheel clockwise nutilthe engraved “T” mark on the flying wheelalin\gns with the engravedline
on the top of the crankcase cover.Swing the rocking arm slightly.A l oose rocking arm(which indicates the existence
of clearance) shows that the pi ston is i n the upper stop position of the compressing t\stroke, where the valve can be
adjusted. A tight rocking arm means thar the piston is in the lower stop position of the compressing stroke, In this
case, continuously turn the “T” key clock wise for 360 degrees until the alignment of those engravd marks, where the
valve canbe adjustd,Af terwards, check the valve gap by inserting a feeler in betweenthe valve adjusting screw and
the end of the valve.
The specified air valve gap :0.05mm for the intake and exhaust valves respecively.
Brake Checking
(1) pull up the front andrearbrakes respectively and check for wearof the brake shoes. If the mark“△”onthe
brake drum cover aligns with that “△ ” on the brake cam, it means that the brake shoes are already worn to the limit
andhave to be replaced.
(2) Replacement should be carriedout at a designated service center and it is recommended that the parts made
byour company areusedtherein.
17
AdjustmentofFrontBrake
(1) The front brake has a free operating
movement of 10-20mm as shown in the figure on the
right side.
(2) inspect the reseivoir capacity and refill if
necessary in order to maintain proper level in the
reservior.This should be the major project of your
regular inspection
(3) check the front brake lining for its worm
depth.if its worn depth is up to the limited mark,
replace the brake lining.if the lining doesn’t have
limited mark but a concave slot as the figure,replace
the lining while its worn depth up to the bottom of
concave slot.replacement of a pair of linings shall be
conducted sumultaneously despite only one of them
is worn.
18
Adjustment ofRearBrake
★The vehicle should be supported by the main stand for check.
(1) The rear brake pedal has a free operating movement of 20-30mm as
shown in the figure on the right side.
(2) To make adjustment, turn the rear brake adjusting nut clockwise to
reduce snd counter clock wise to increase the free operating movement of the
brakepedal.
Adjustment of Chain
1.When regulation is needed. Ioosen the rear axle
nut
2.Turn the chail adjusting nuts
on the left and right sides to adjust the tension of the chain and to align the
marking of the chain adjuster with the engraved lines in the similar position,
on both sides.
3.Tighten the lock nut and rear axke nut by a torque of 35-50Nm.
4. Repetitively check the tension of the chain.
5.When the rearwheel is changed in position and the chain adjusted, the
free operating movement of the rear brake pedal will be affected, which,
therefore, should be checkedthereafter and alsoregulated if necessary
19
[Greasing procedures tothe driving chain]
1.Shut off the engine.
2.Add some machine oil or chain grease to the driving chain.
Attention:
When the rear wheel axil has moved to the back adjust ing limit , if excess loose be cause of wearing to the
driving chain, please change with a new one.
20
VehicleWashing
Cleaning the vehicle reularly can slow down the color fading of its body and make it easier to check if there is
anydamage and oil leakage with if.
Caution:
Washing the motorcycle with over-pressurized water may cause damage to some of its components. Therefore,
do not jet over-pressurized water directly on to the following parts:
——Wheel hub
—— Exhaust pipe
——Fuel tank and lower portion of cushion
——Carburetor
——Head lock andignition switch
——Meters
(1) After pre-wiping ,the vehicle should be washed with clean water to remove dirty residues so as to prevent
corrosion. Plastic subassemblies should be cleaned by wiping with cloth or foam soaked i n neutral detergent solution,
followed by washing with cleanwater.
(2) Afterthe cleanedvehicle is air dried, greasethe chain andrun the engine atidling speedfor a fewminutes.
