1987 Kawasaki Ninja 750R / GPX750R Service Manual (P/N 99924-1079-01)

• Exact coverage: 1987 Kawasaki Ninja 750R and GPX750R, model ZX750-F1, beginning with frame number JKAZXDF1□HB500001 (the boxed character varies by machine) or ZX750F-000001.
• Factory publication: a 201-page PDF reproduction of Kawasaki Part No. 99924-1079-01, First Edition, August 31, 1986, with specifications and annotations for U.S., California, Canadian, European, Australian, Austrian, and South African configurations.
• Fuel and top-end procedures cover Keihin CVK34 carburetor synchronization and service fuel-level adjustment, U.S. clean-air checks, California evaporative-emissions testing, cam-chain timing, valve-clearance adjustment, cylinder compression, valve-guide and seat repair, and piston/cylinder inspection.
• Bottom-end and drivetrain work includes engine removal, crankcase splitting and assembly, crankshaft and connecting-rod bearing-insert selection, starter-clutch service, six-speed constant-mesh transmission disassembly and assembly, positive-neutral-finder service, shift-drum work, hydraulic clutch repair and bleeding, and oil-pressure testing.
• Wheels, final drive, and brakes are handled through wheel and hub-bearing service, tire and rim inspection, balance-weight installation and removal, endless O-ring chain and sprocket work, caliper and master-cylinder repair, brake-fluid replacement, line bleeding, and post-installation checks.
• Suspension and steering sections detail ESCS fork adjustment, fork disassembly and assembly, seal and bushing replacement, rear-shock air and damping adjustment, Uni-Trak, swingarm, tie-rod and rocker-arm service, plus steering-stem adjustment and bearing replacement.
• Electrical coverage includes alternator-belt adjustment and alternator overhaul, charging-system tests, pickup and ignition-coil checks, IC-igniter diagnosis, starter-motor service, headlight reserve-lighting operation, cooling-fan tests, gauges, sensors, relays, diodes, and market-specific wiring diagrams.

This is Kawasaki's factory workshop reference for the 1987 ZX750-F1, not a multi-year Ninja/GPX 750 compilation. Kawasaki states that it was prepared primarily for trained mechanics in a properly equipped shop. Owners with basic mechanical knowledge and the correct tools can use it for basic maintenance and repair, while internal-engine, hydraulic, and electrical work assumes sound workshop practice.

Market-Specific Fuel, Emissions, and Electrical Systems

Variant symbols distinguish U.S., California, Canadian, U.K., French, West German, Italian, Spanish, Swiss, Austrian, Australian, and South African specifications. The California-only evaporative-emission section covers the canister, liquid/vapor separator, color-coded hose routing, inspections, and separator operation test. U.S. models receive separate air-suction-valve inspection and vacuum-switch-valve testing. North American electrical coverage also explains the headlight reserve-lighting system and the relay differences in the junction box.

The named visual references include the ZX750-F1 Wiring Diagram (US and Canada), ZX750-F1 Wiring Diagram (Other than US and Canada), Coolant Flow Chart, Engine Oil Flow Chart, Ignition Circuit, and IC Igniter Troubleshooting flowchart. System chapters add exploded assembly views for the cylinder head and cam drive, clutch, crankshaft/transmission, brakes, and suspension, with assembly symbols for torque, locking agent, sealant, grease, and oil.

Engine and Drivetrain Repair Depth

The engine material is specific to the DOHC, liquid-cooled four-cylinder powerplant and moves well beyond tune-up data. It documents cylinder-head removal, camshaft and rocker service, chain-timing installation, valve-guide replacement, valve-seat cutting and lapping, cylinder and piston work, oil-pump service, and pressure diagnosis. Cooling procedures cover filling, pressure testing, water-pump inspection, radiator and cap service, thermostat testing, and fan-switch and temperature-sensor checks.

Crankshaft repair includes Plastigage inspection and factory bearing-selection tables keyed to crankcase, connecting-rod, crankpin, and main-journal markings, with bearing colors and part numbers. Transmission coverage follows the shafts, gears, circlips, bushings, shift forks, and shift drum through disassembly, inspection, and assembly.

The non-return cam-chain tensioner can damage the chain or upset timing if it is partly loosened or the crankshaft is turned while the tensioner is out; incorrect timing can damage the valves. Camshaft caps are machined with the cylinder head, so installing a cap in the wrong location can leave improper oil clearance and seize the camshaft.

Factory Data, Tools, and Scope

Reference material includes component torque tables, fluid grades and capacities, pressure-test data, electrical resistance and charging specifications, clearance and runout standards, service limits, wear measurements, cable and hose routing, and a fault guide spanning starting, fuel, ignition, overheating, clutch, shifting, noise, handling, brakes, and charging.

Representative factory tool callouts include Fuel Level Gauge 57001-1017, Vacuum Gauge 57001-1198, Valve Adjuster 57001-1232, Clutch Hub Holder 57001-305, Oil Pressure Gauge 57001-164 with Adapter 57001-1233, and Alternator Tension Wrench 57001-1235. Kawasaki's separate Parts Catalog and Special Tool Manual are referenced but are not part of this PDF.

Factory safety notes address possible asbestos in period brake and clutch friction materials, high-voltage ignition, battery charging, hydraulic brake and clutch work, and the battery-fed radiator fan, which may start with the ignition off. The motorcycle must be securely supported for wheel, engine, steering, or suspension repair.
