1-2 GENERAL INFORMATION 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. A WARNING Indicates a potential hazard that could result in death or injury. I A CAUTION I 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 advice. GENERAL PRECAUTIONS A WARNING * Proper service and repair procedures are important for the safety of the service mechanic and the safety and reliability of the motorcycle. * When two 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 out- doors. * 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 manufacturer's instructions. * Never use gasoline as a cleaning solvent. * To avoid getting burned, do not touch the engine, engine oil, radiator, and exhaust system until they have cooled. * After servicing the fuel, oil, engine coolant, exhaust or brake systems, check all of the lines, and fittings related to the system for leaks.

GENERAL INFORMATION 1-3 I A CAUTION I * 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. * 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 lubricants, bonds, or sealants. * When removing the battery, disconnect the e battery lead wire first, then the (±) battery lead wire. * When reconnecting the battery, connect the (±) battery lead wire first, then the e battery lead wire. Finally, cover the (±) battery terminal with the terminal cover. * When performing service to electrical parts, disconnect the e battery lead wire, unless the service procedure requires the battery power. * When tightening cylinder head and crankcase nuts and bolts, tighten the larger sizes first. Always tighten the nuts and bolts from the inside working out, diagonally and to the specified torque. * Whenever you remove oil seals, gaskets, packing, O-rings, self-locking nuts, locking wash- ers, cotter pins, circlips, and other specified parts, 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 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, engine coolant, all other fluids, batteries, and tires. * To protect the earth's natural resources, properly dispose of used motorcycles and parts.

1-4 GENERAL INFORMATION SUZUKI DR-Z400SY (2000-MODEL) RIGHT SIDE LEFT SIDE * Difference between photographs and the actual motorcycle depends on the markets. SERIAL NUMBER LOCATION The frame serial number or V.I.N. (Vehicle Identification Number) G) is stamped on the right side of the steering head pipe. The engine serial number ® is located on the right side of the crankcase. These num- bers are required especially for registering the machine and ordering spare parts. FUEL, OIL, AND ENGINE COOLANT RECOMMENDATIONS FUEL (FOR USA AND CANADA) • Use only unleaded gasoline of at least 87 pump octane ( R ~ M ) method or 91 octane or higher rated by the Research Method. • SUZUKI recommends that customers use alcohol-free unleaded gasoline whenever possible. • Use of blended gasoline containing MTBE (Methyl Tertiary Butyl Ether) is permitted. • Use of blended gasoline/alcohol fuel is permitted, provided that the fuel contains not more than 10% ethanol. Gasoline/alcohol fuel may contain up to 5% methanol if appropriate cosolvents and corrosion inhibitors are present in it. • If the performance of the motorcycle is unsatisfactory while using blended gasoline/alcohol fuel, you should switch to alcohol-free unleaded gasoline. • Failure to follow these guidelines 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.
