The FOREWORD has stated that correct running-inoperation is important to prolong the service life and makingthe best of a new motorcycle. This chapter provides the correctmethods of running-in operation.

The maximum speed limits for a new motorcycle duringthe running-in period are shown as below. First 800km Less than 5,000 rpm To 1,600km Less than 7,500 rpm Over 1,600km Less than 10,000 rpm

The engine speed should be changed often, instead ofbeing kept steady, so that each component of the engineacquires a “loaded” pressure. When the pressure is “unloaded”,the components will be cooled down. Such process contributesto the engagement of the components. In order to ensure afine fitness, it’s important to give a load to each of thecomponent in the trial riding. But mind that the engine mustnot be overloaded.

When the engine is running at a constant low speed, the

components will be polished well but will not be fitted well.You may engage to different gears to speed up, provided thatthe above speed limits are not exceeded. However, during thefirst 1,600 km, never turn the throttle to the maximum position.

After the engine has been started, no matter cold orwarm, let the engine run at idle speed for an adequate periodof time before adding any load, so that the engine oil can flowto each of the important components.

The maintenance after the first 1,000-km of mileage isof uttermost importance to your motorcycle. At the time ofrunning-in, all the components of engine are run in, and all theother parts are also engaged. All the necessary adjustments,tightening and replacement of contaminated gear oil should bedone in time.

The timely maintenance after the first 1,000-km willcontribute to a long lifetime and good performances.

CAUTIONThe maintenance after the first 1,000-km should be

carried out in accordance with MAITENANCE SCHEDULEof this manual. Pay special attention to the WARING andCAUTION in the section.

15

Before starting to ride your motorcycle each time, checkthe items listed below. Never underestimate the importanceof these checks.

Check if the throttle switch is set to ON position. Insertthe ignition key into the switch and turn clockwise to ON. Ifthe transmission system is currently in neutral mode, theneutral indicator should be lit.

CAUTIONWhen starting the engine, the gearshift should be

in neutral mode and the clutch switched on, and therider sits on the correct position.

1. The ignition switch is set to ON position;2. Use the choke system.3. Step on the starting rod two or three times.4. Quickly turn the ignition switch to ON. Step on the

starting rod to start the engine.Press the choke lever fully down. The throttle valve is

closed. Press the starter button to start the engine. As soon asthe engine is started, pull the lever up by half and let theengine warm up sufficiently. Then release the lever. The coolerthe weather becomes, the longer the time requires warmingup.

1. The ignition switch is set to ON position2. Turn the throttle grip by 1/8 to 1/4 cycle.3. Step on the starting rod to start the engine. or push

the electric starter button down. When stating the engine as itis warm, the choke system is unnecessary.

WARNINGNever start the engine in an enclosed area with

bad ventilation conditions. The CO in the tail gas isradically toxic. Never keep the motorcycle running ashort while without monitoring.

CAUTIONNever let the engine running for prolonged time

in stationary condition. Otherwise the engine may getoverheated and the engine assemblies may be damaged.

While gripping the clutch lever and then waiting amoment, press the gear lever to engage the bottom gear. Twistthe throttle grip counterclockwise and release the clutch leverslowly and gradually. When the clutch is engaged, themotorcycle will set out.

To shift to a higher gear, first slow down gradually, therelease the throttle and grip the clutch lever. Move the leverto the next higher gear and release the clutch lever. Then twistthe throttle grip slightly. Repeat this procedure and you willbe able to shift to the top gear.

The gearshift is capable of making the engine smoothrunning within a normal range of operation. The transmissionratio is carefully designed to be compliance with thecharacteristic of the engine. The rider should select the mostsuitable gear under general condition. Never slide the clutchfor the purpose of controlling the speed. Shift to lower gearsas necessary to get the engine working at normal speed.

CAUTIONThe engine rotary speed at any gear should not

exceed the red area of the tachometer.

When the motorcycle runs upwards on a steep slope, itwill slow down and demonstrates a lack of power. Now shiftto a lower gear so that the engine resumes normal operation.The action of gear shifting should be performed swiftly;

17

otherwise the motorcycle will lose the forward-rushing force.When the motorcycle runs downwards along a slope,

shift to lower gears to that the motorcycle can be brakedeasily.

Bear in mind that the speed should not be too high indownward riding.

WARNINGIf this is the first time for you to ride this type of

motorcycle, make sufficient practice at a traffic-freearea till you fully get familiar with the operation of themotorcycle.

Before you start and stop the motorcycle, set theside stand to the normal upward position.

Before you start turning, decelerate to a safe speed.Never shift the gear at the time of turning.

It is extremely dangerous to ride your motorcyclewith a single hand. Hold the handlebars firmly withboth hands. Rest your feet on the footrests. Never letboth hands leave the handlebars at the same time.

Because the tire friction becomes low on wet andsmooth surface, the braking and turning abilities

decrease naturally. Slow down your motorcycle in suchcase.

Observe the traffic codes and regulations andcontrol speeds.

Release the throttle grip clockwise to close the throttlecompletely.

Apply both the front and rear brakes evenly.Decrease the speed by shifting the gear.Before the motorcycle stops, grip the clutch lever and

shift to the neutral gear so as to stop. Observe the neutralindicator to confirm the neutral gear.

WARINGAs the speed is high, the braking distance will be longer

accordingly. Correctly judge the distance from the vehiclesahead. The distance should be at least enough for you tobrake the motorcycle.

Less-experienced rider tends to use the rear brake only.It will speed up the wearing of the rear brake and make thebraking distance longer.

To use the front or rear brake only may cause loss of

18

control and slippery, and therefore is dangerous. Care shouldbe taken when riding on a wet or slippery road and at acurving road. In such cases, use the brakes gently. Hurriedbraking on a slippery or uneven road is especially dangerous.

If the motorcycle must be supported with the side standon a gentle slope, the bottom gear should be engaged in orderto prevent unexpected sliding from the stand. Return to theneutral gear prior to starting the engine.

Turn the ignition Switch to OFF Step the engine.Remove the key from the switch.Lock the steering lock for safety.

The following table gives the schedule of check andmaintenance according to the intervals based on odometerreading or the number of months. At the end of each interval,the required check, inspection, lubrication and other serviceshould be carried out. If your motorcycle has been used underbad conditions, for example, continuously running with largethrottle in a windy or dusty environment, necessarymaintenance should be done each time after operation in orderto guarantee its reliability. Our authorized dealers can provide

further maintenance, instructions. The steering assembly,shock absorbing system and the wheel system require thespecial and careful maintenance. for they are the keycomponents of the motorcycle.

For the sake of safety, it is advised that qualified workersshall service these components.

The maintenance after the running-in periodmust be carried out as soon as the odometer readingreaches to 1,000 km. Timely maintenance contributesto the safety and reliability. Carry out the regularmaintenance thoroughly according to the instructionsof this manual.

CAUTIONIt may be necessary to replace one or more parts

during the regular maintenance. It is recommendedthat you use genuine Qingqi brand parts or theirequivalents.

WARNINGOnce the battery is put into use, no diluted sulfuric

acid should be poured into the battery any longer.CAUTION

Do not band, block or change the air vent pipe ofthe battery. Ensure one end of the air hose is connectedclosely to the battery fitting and the other end is alwayskept open. The air vent pipe should not be mistakenand the battery should be placed in the right position.

Make sure that the polarities of the batteryterminals are correctly connected. The red lead mustbe connected to the positive terminal and the blacklead to the negative terminal. Any mistake in wiringmay cause damage to the charging system and thebattery itself.

Note: For the first 1,000 km and every 3,000 km, entrustthe authorized dealers to check the electrolyte gravity of thebattery with a gravity gauge. The battery operating conditioncan be judged according to the gravity.

After the first 1,000 km or every 3,000 km, clear out thecarbon deposit attached to the spark plug with a small metalbrush or cleaner. Readjust the spark plug gap with a gap gaugeso as to keep it between 0.6 and 0.8 mm. Replace the plugwith a new one after every 6,000 km.

While cleaning the carbon deposit, observe the color ofthe porcelain tip. The color can tell you if the standard sparkplug apply to your motorcycle. In case of being wet or blackin color, it is more suitable to use high-pressure hot type ofspark plug. The normally worked spark plug usually is lightgray or light brown. If the spark plug is white or seem flashing,it shows that the spark plug works under the overheatcondition. In such case, renew the spark plug with a cold typeone.

22

CAUTIONThe standard spark plug available to this type of

motorcycle is carefully chosen to suit most of the workingscope. If the color of spark plug is different from the standardone, consult with dealers before changing other types ofspark plugs with different heat-resisting range. Selection ofimproper spark plug will lead to serious damage to the engine.Choosing improper spark plugs can make operation verydifficult. So contact with your dealer before using otherbrands of spark plugs.

of driving chain so that the movable distance between the twochain wheels is kept within 25-35 mm.

1. Support the motorcycle with the center stand.2. Remove the cotter pin and loose the nut of rear wheel

shaft.3. Screw out the locking nut.4. The chain can be adjusted by turning the adjusting

bolt clockwise and counterclockwise.Note:When a new chain is replaced, the two chain wheels

must be checked. If necessary. make replacement.CAUTION

The opening end of chain joint should be installedin reverse to the turning direction.

(1) Joint clip (2) Rotating directionThe dust and dirt on the driving chain will increase the

wearing of the chain itself and chain wheels. Therefore, cleanthe driving chain with cleaning agent and then lubricate itusing special lubricant or motor oil after riding for every1,000 km.

After the first 1,000 km and every 3,000 km, check theair pressure and tire tread. For the sake of safety and longerservice time, the air pressure of tire should be often checked.

If the air pressure of tires is not sufficient, it will notonly speed up the wearing of tire, but also extremely affectthe stability of motorcycle. Insufficient air pressure makes

the motorcycle difficult to turn. But excessive air pressuremay decrease the contact area between the tire and ground,lead to the slipping of motorcycle and even losting of control.The air pressure should be always kept within the specifiedlimit. Adjust the air pressure when the tire is cold.

Air pressure of tires: Front tire: 175kpaRear tire:225kpa

Riding on the motorcycle with its tire excessively wornwill decrease the stability of operation, and may be out ofcontrol accordingly. When the depth of outer tire tread isreduced to 1.6 mm(0.06 inch) or less than this value,replacement of outer tire is recommended.

33

WARNINGThe air pressure of tires is very important for

keeping motorcycle’s normal performance and safety.There fore, often check the wearing state and airpressure of tires.

In order to reduce the pollution caused by exhausting ofwaste gas and noise, pay attention to the following points:

Clean according to the following steps.

1. Pour the noncombustible cleaning solution into anadequate plate and immerse the filter element in the solutionto clean it.

2. Hold and press the cleaned filter element with two

hands and squeeze the cleaning solution out of it. Do nottwist the filter element to avoid cracking.

3. Soak the filter element into the pool of motor oil andsqueeze the oil out of the element and let it slightly wet.

CAUTIONCheck to see if the filter element has crack before

or during cleaning. If any crack is found, renew thefilter element.

4. Reassemble the cleaned filter in the reverse order ofremoval. Make sure that the filter element is firmly installedin the specified position and sealed properly.

Observe the abnormal sound of the engine.

If it is not able to start the engine, check the followingitems to find the cause.

1. Check if the fuel in the tank is sufficient.2. See if the fuel flows to the carburetor through the tap.3. Disconnect the fuel hose from the carburetor, turn the

tap to ON position, and check if gasoline flows out of the hose.

4. Make sure the fuel has flown to the carburetor, thenproceed to check the ignition system.

WARNINGWhen checking the fuel system, do it at a spacious

area with no smoking.

1. Dismount the spark plug and reconnect it to thecylinder head.

2. Set the ignition switch to ON position to allow theignition close to the engine and start the engine. If the ignitionsystem works normally, there is blue spark jumping throughthe spark plug gap. If no spark appear, contact with thedealer to have it repaired.

WARNINGKeep the spark plug away from the opening plug hole

on the cylinder head, because the spark may ignite thegasoline steam in the cylinder, causing fire.

1. Check the fuel in the tank.2. Check the interval spark of the ignition system.3. Check if the idle speed of the engine is normal.

It’s better to contact with the dealer before you makeany repairing. If the warranty period has not expired, youmust get the explicit permission of your dealer before you tryto repair by yourself. Otherwise your operation may voidthe warranty.
