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
every800-1,000km 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 position.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
lower lines of the oil gauge.
Do not use any machine oil of a
different grade than the specified one
to avoid machinery failure.

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

Air Valv
e
Gap
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 checkedperiodically.
The gap of the air valve should be inspected and adjusted with a cold engine by the following procedures:
1.Remove the caps of the central hole and the top hole (the ignition timing observation hole)in the left crankcase
cover.
2.Remove the caps of 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 nutil the engraved “T” mark on the flying wheel alin\gns with the engraved line
on the top of the crankcase cover.Swing the rocking arm slightly.A loose rocking arm(which indicates the existence
of clearance) shows that the piston is in 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 can be adjustd,Afterwards, check the valve gap by inserting a feeler in between the 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 wear of 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
and have to be replaced.
(2) Replacement should be carried out at a designated service center and it is recommended that the parts made
by our company areused therein.

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
