WARNING/CAUTION/NOTE

Indicates a potential hazard that could result in death or injury.

Indicates a potential hazard that could result in motorcycle damage.

NOTE:

Indicates special information to make maintenance easier or instructions clearer.

GENERAL PRECAUTION

WARNING

Please read this manual and follow its instructions carefully. To emphasize special information, the

symbol and the words WARNING,CAUTION and NOTE have special meanings. Pay special attention to

the messages highlighted by these signal words.

Please note, however, that the warnings and the cautions contained in this manual cannot possibly cover

all potential hazards relating to the servicing, or lack of servicing of the motorcycle. In addition to the

WARNING and CAUTION stated, you must use good judgment and basic mechanical safety principles. If

you are unsure about how to perform a particular service operation, ask a more experienced technician for

advice.

Proper service and repair procedures are important for the safety of the service technician and the

safety and reliability of the motorcycle.

When 2 or more persons work together, pay attention to safety of each other.

When it is necessary to run the engine indoors, make sure that exhaust gas is forced outdoor.

When working with the toxic or flammable materials, make sure that the area you work in is well-

ventilated and that you follow all of the material manufacturer's instructions.

Never use gasoline as a cleaning solvent.

To avoid getting burned, do not touch the engine, engine oil or exhaust system during or for a while

after engine operation.

After servicing fuel, oil, exhaust or brake system, check all lines and fittings related to the system

for leakage.

GENERAL INFORMATION

NOTE:

If parts replacement is necessary, replace the parts with SUZUKI GENUINE PARTS or their

equivalent.

When removing parts that are to be reused, keep them arranged in an orderly manner so that they

may be reinstalled in the proper order and orientation.

Be sure to use special tools when instructed.

Make sure that all parts used in reassembly are clean, and also lubricated when specified.

When use of a certain type of lubricant, bond, or sealant is specified, be sure to use the specified

type.

When performing service to electrical parts, if the service procedures not require used of battery

power, disconnect the positive terminal.

When removing the battery, disconnect the negative cable first and then the positive cable.

When reconnecting the battery, connect the positive cable first and then the negative cable, and

replace the terminal cover on the positive terminal.

Tighten cylinder head and case bolts and nuts, beginning with larger diameter and ending with

smaller diameter, from inside to outside diagonally, to the specified tightening torque.

Whenever you remove oil seals, gaskets, packing, O-rings, locking washers, cotter pins, cir-clips,

and certain other parts as specified, be sure to replace them with new ones. Also, before installing

these new parts, be sure to remove any odd material from the mating surfaces.

Never reuse a circlip. When installing a new circlip, take care not to expend the end gap larger than

required to slip the circlip over the shaft. After installing a circlip, always ensure that it is completely

seated in its groove and securely fitted.

Do not use self-locking nuts a few times over.

Use a torque wrench to tighten fasteners to the torque values when specified. Wipe off grease or oil

if a thread is smeared with them.

After reassembly, check parts for tightness and operation.

To protect environment, do not unlawfully dispose of used motor oil and other fluids,

batteries and tires.

To protect earth's natural resources, properly dispose of used motorcycles and parts.

SERIAL NUMBER LOCATIONS

The frame serial number or V.I.N. (Vehicle

Identification Number) 1 is stamped on the right

side of the steering head pipe. The engine serial

number 2 is located on the left side of the

crankcase. These numbers are required

especially for registering the machine and

ordering spare parts.

FUEL AND OIL

RECOMMENDATIONS

FUEL

Use fuel with an octane number of 90-97

(Research method), preferably unleaded.

NOTE:

Unleaded fuel will extend spark plug life.

ENGINE OIL

Be sure that the motorcycle engine oil you use

comes under API classification of SF or SG and its

viscosity rating is SAE 10W-40. If SAE 10W-40

engine oil is not available, select the oil viscosity

according to the following chart:

SAE

20W/50

10W/50

10W/30

Temp.

BREAK-IN PROCEDURE

During the manufacture only the best ossible

are used and all machined parts are

finished to a very high standard

allow the moving part to “BREAK-IN”

subjecting the engine to maximum stresses

s the care and restraint exercised during

its early life The general rules are as follows:

materials

, it is still necessary

to before

.The

future performance and reliability of the engine

depend on

GENERAL INFORMATION

The throttle must not be opened to the full during

the new motorcycle's break-in period. Throttle

opening should be limited to less than 3/4 of its

maximum, while violent acceleration should be

avoided.

Do not maintain constant engine gear and

speed for an extended time period during any

portion of the break-in. Try to vary the throttle

position. During the period of break-in, increase

the throttle opening properly to enable break-in

fully.

When engine is running at constant low speed

(low load), parts will wear rapidly leads to bad

brake-in.
