• Engine and drivetrain repair: Covers compression testing, camshaft-chain timing, valve-clearance adjustment and seat repair, piston and cylinder inspection, engine removal, crankcase splitting, crankshaft and connecting-rod service, clutch work, and six-speed transmission disassembly and inspection.
• Chassis service: Includes wheel and tire work, drive-chain alignment, caliper and master-cylinder repair, brake-line bleeding, pneumatic fork overhaul, anti-dive testing, AVDS/TCV troubleshooting, Uni-Trak linkage service, and steering-head bearing replacement.
• Electrical diagnosis: Provides charging, ignition, starter, lighting, fan, gauge, switch, sensor, relay, junction-box, and wiring tests, supported by regional wiring diagrams, circuit inspections, and electrical specifications.

This 264-page PDF reproduces Kawasaki’s GPZ500R/GPZ600R Motorcycle Service Manual, Part No. 99924-1055-04, Fourth Edition, dated November 30, 1995. Kawasaki states that the manual was prepared primarily for trained mechanics in a properly equipped shop, while owners with basic mechanical knowledge, correct tools, and workshop-procedure experience can use it for basic maintenance and repair.

Exact Model and Frame Application

Starting frames are ZX500A-000001 (A1), ZX500A-000801 (A2), and ZX500A-001601 (A3); ZX600A-000001 (A1), ZX600A-025001 (A2), ZX600A-046001 (A3), ZX600A-054001 (A4), and ZX600A-055801 (A5). The B1 application begins at JKAZX4B1□HA000001, with □ identified by Kawasaki as a variable digit; long-form VIN alternatives are also listed for the early ZX600-A models.

Regional marks distinguish US, California, Canadian, West German, Italian, Swiss, and South African specifications, with further European applications shown where relevant. These distinctions affect carburetor settings, spark-plug applications, tires, lighting and switch circuits, emissions equipment, and other market-dependent service data.

How the Later-Model Supplement Works

The main chapters establish the 1985 A1 procedures. Chapter 17 supplies only the changes unique to the 1986–1989 motorcycles, so later-model repair work requires the base section and supplement together. The supplement treats the 1987 ZX600-B1 as an A3 unless noted otherwise, then adds its aluminum-frame, engine-mounting, and steering differences. It also documents 1987–1989 transmission revisions, 1989 tire applications, the ZX600-A5 maintenance chart and wiring diagram, 1989 Swiss clean-air equipment, and model-specific carburetor data.

Shop Data, Diagrams, and Special Tools

Exploded views carry assembly notes for torque, lubrication, sealant, locking-agent, and replacement-part requirements. Specifications cover fastener torque, clearances, wear limits, bearing selection, fluid capacities, pressure and electrical tests, and adjustment data. The periodic maintenance charts are separated where the 1989 A5 schedule differs.

Useful visual references include the engine-oil flow chart, camshaft and sprocket timing illustration, California evaporative-emission hose layout, TCV troubleshooting chart, US/Canada and other-market wiring diagrams, and the separate 1989 ZX600-A5 wiring diagram. Named tool callouts include Vacuum Gauge & Tachometer 57001-1291, Pilot Screw Adjuster 57001-1292, Clutch Holder 57001-1243, Kawasaki Hand Tester 57001-983, and the 1987–1989 Rotor Puller Adapter 57001-1244.

The electrical section warns that striking the alternator rotor can cause its magnets to lose magnetism, while a megger or high-capacity meter can damage the IC igniter. Fork overhaul notes also flag that tapping the outer tube while the fork lies horizontal can damage the inner-tube guide bushing.

This publication is not a parts catalog; Kawasaki directs spare-parts identification to a separate Parts Catalog. Because the manual warns that some original brake, clutch, gasket, and insulating materials may contain asbestos, follow its dust-control, ventilation, and disposal precautions before disturbing those components.
