WARNING/CAUTION/NOTE
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 mes-
sages highlighted by these signal words.
!
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.
Please note, however, that the warnings and 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 WARN-
INGS and CAUTIONS stated, you must use good judgement and basic mechanical safety principles. If you
are unsure about how to perform a particular service operation, ask a more experienced mechanic for ad-
vice.
GENERAL PRECAUTIONS
!
* Proper service and repair procedures are important for the safety of the service mechanic and
the safety and reliability of the motorcycle.
* When 2 or more persons work together, pay attention to the safety of each other.
* When it is necessary to run the engine indoors, make sure that exhaust gas is forced outdoors.
* When working with 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, oil cooler and exhaust system until
they have cooled.
* After servicing the fuel, oil, exhaust or brake systems, check all lines and fittings related to the
system for leaks.

GENERAL INFORMATION 1-3
"
* If parts replacement is necessary, replace the parts with Suzuki Genuine Parts or their equiva-
lent.
* 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. Lubricate them when specified.
* Use the specified lubricant, bond, or sealant.
* 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.
* When performing service to electrical parts, if the service procedures not require use of battery
power, disconnect the negative cable the battery.
* When tightening the cylinder head and case bolts and nuts, tighten the larger sizes first. Al-
ways tighten the bolts and nuts diagonally from the inside working out and to the specified
tightening torque.
* Whenever you remove oil seals, gaskets, packing, O-rings, locking washers, self-locking nuts,
cotter pins, circlips 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 left over material from the mating
surfaces.
* Never reuse a circlip. When installing a new circlip, take care not to expand 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.
* Use a torque wrench to tighten fasteners to the specified torque. Wipe off grease and oil if a
thread is smeared with them.
* After reassembling, check parts for tightness and proper operation.
* To protect the environment, do not unlawfully dispose of used motor oil and other fluids: batter-
ies, and tires.
* To protect Earth’s natural resources, properly dispose of used motorcycle and parts.

1-4 GENERAL INFORMATION
SUZUKI GSF600SY (2000-MODEL)
SERIAL NUMBER LOCATION
The frame serial number or V.I.N. (Vehicle Identification Number) 1is stamped on the right side of the
steering head pipe. The engine serial number 2is located on the right side of the crankcase. These numbers
are required especially for registering the machine and ordering spare parts.
FUEL AND OIL RECOMMENDATION
FUEL (For Canada)
1.Use only unleaded gasoline of at least 87 pump octane ( ) method or 91 octane or higher rated by the
research method.
2.Suzuki recommends that customers use alcohol free, unleaded gasoline whenever possible.
3.Use of blended gasoline containing MTBE (Methyl Tertiary Butyl Ether) is permitted.
4.Use of blended gasoline/alcohol fuel is permitted, provided that the fuel contains not more than 10% etha-
nol. Gasoline/alcohol fuel may contain up to 5% methanol if appropriate cosolvents and corrosion inhibitors
are present in it.
5.If the performance of the vehicle is unsatisfactory while using blended gasoline/alcohol fuel, you should
switch to alcohol-free unleaded gasoline.
6.Failure to follow these guideline could possibly void applicable warranty coverage. Check with your fuel
supplier to make sure that the fuel you intend to use meets the requirements listed above.
FUEL (For the others)
Gasoline used should be graded 91 octane (Research Method) or higher. An unleaded gasoline is recom-
mended.

* Difference between photograph and actual motorcycle depends on the markets.

GENERAL INFORMATION 1-5
ENGINE OIL
Use a premium quality 4-stroke motor oil to ensure longer ser-
vice life of your motorcycle. Use only oils which are rated SF or
SG under the API service classification.
The recommended viscosity is SAE 10W-40. If an SAE 10W-40
motor oil is not available, select an alternative according to the
right chart.
BRAKE FLUID
Specification and classification: DOT 4
!
Since the brake system of this motorcycle is filled with a glycol-based brake fluid by the manufac-
turer, do not use or mix different types of fluid such as silicone-based and petroleum-based fluid
for refilling the system, otherwise serious damage will result.
Do not use any brake fluid taken from old or used or unsealed containers.
Never re-use brake fluid left over from a previous servicing, which has been stored for a long
period.
MULTIGRADE
TEMP.
FRONT FORK OIL
Use fork oil #10 or equivalent fork oil.
BREAK-IN PROCEDURES
During manufacture only the best possible materials are used and all machined parts are finished to a very
high standard but it is still necessary to allow the moving parts to “BREAK-IN” before subjecting the engine to
maximum stresses. The future performance and reliability of the engine depends on the care and restraint
exercised during its early life. The general rules are as follows.
• Keep to these break-in engine speed limits:
Initial 800 km (500 miles): Below 6 000 r/min.
Up to 1 600 km (1 000 miles): Below 9 000 r/min.
Over 1 600 km (1 000 miles): Below 12 000 r/min.
• Upon reaching an odometer reading of 1 600 km (1 000 miles) you can subject the motorcycle to full throttle
operation. However, do not exceed 12 000 r/min. at any time.
CYLINDER IDENTIFICATION
The four cylinders of this engine are identified as No.1, No.2, No.3 and No.4 cylinder, as counted from left to
right (as viewed by the rider on the seat).
