1979–1985 Kawasaki KZ500/KZ550/ZX550 Clymer Service & Repair Manual (P/N M449)

This Clymer service and repair manual covers the 1979–1985 Kawasaki KZ500, KZ550, and ZX550, including GPZ and LTD variants. The base chapters and the 1982 and Later Service Information supplement work together, with the supplement identifying procedures and specifications that differ on later models.

• Engine repair: Engine removal, crankcase separation, cylinder head work, camshaft timing, valve-clearance adjustment, and crankshaft inspection, supported by torque and wear-limit tables.

• Clutch and transmission: Wet-clutch inspection, clutch-release adjustment, transmission disassembly, and checks of shift drum assemblies, shift forks, and transmission gears.

• Fuel and emissions: Carburetor cleaning, synchronization, fuel-level inspection, air suction valve testing, and model-specific evaporative emission system service.

• Electrical diagnosis: Contact breaker points and transistorized ignition service, alternator stator checks, charging-system diagnosis, starter testing, and model-specific wiring diagrams.

• Brakes: Hydraulic disc brake bleeding, pad and disc inspection, drum brake service, and master cylinder and caliper removal.

• Suspension and steering: Front fork disassembly, steering head bearing service, Uni-Trak linkage inspection, rear shock checks, and ZX550 anti-dive testing.

• Lubrication and final drive: Engine oil/filter service, drive-chain adjustment, and shaft-drive maintenance, with model-specific fork-oil and final-drive lubricant capacities.

Written for owners and home mechanics, the manual explains routine maintenance and major repairs while identifying work that requires specialized equipment or a qualified repair shop.

Engine Inspection, Timing and Bearing Selection

Component photographs and the Cam Chain and Tensioner exploded view support top-end and bottom-end work. Torque specification tables cover internal engine components and cylinder head hardware; bearing clearance checks use Plastigage and insert-selection data.

ZX550 camshaft sprocket alignment and Main Bearing Insert Selection tables help distinguish its assembly requirements from earlier KZ procedures. The tensioner section also identifies early KZ550 engines below engine number 9031 and warns that incorrect crosswedge-tensioner handling can damage the cam chain.

Carburetor Service and Emission Controls

Slide-type Teikei carburetors and the later constant-velocity carburetors have separate service instructions. Diaphragm inspection, fuel-level checks, and synchronization are tied to the applicable carburetor arrangement, helping owners select the adjustment procedure for their setup.

Air suction valves and the vacuum-operated switching system are covered alongside the evaporative emission controls fitted to California ZX550 models. Fuel and ignition work involves fire and electrical hazards; review the manual's safety instructions before service.

Ignition, Charging and Instrument Diagnosis

Step-by-step documentation covers ignition timing mark alignment across both contact-breaker and transistorized systems, with separate pickup-coil and IC-igniter tests.

The 3-Phase Charging System schematic relates stator and regulator/rectifier checks to the circuit, while the ZX550 Starter System diagram supports relay and interlock fault tracing.

The supplement also covers LCD warning displays, with an LCD Gauge and Wiring System diagram and connector assignments for tracing warning-light and gauge faults. These references help separate a failed sender or circuit connection from an instrument-panel fault.

Brakes, Suspension and Final Drive

The brake chapters distinguish front and rear disc systems from the rear drum brake. Master cylinder and caliper coverage includes removal and exploded views, but rebuilding is referred to a brake specialist.

Conventional forks, steering head bearings, and air-assisted shocks have model-specific service sections, with suspension fastener torques and wear limits. The Uni-Trak exploded view identifies rocker and tie-rod bearing locations for linkage inspection.

ZX550 anti-dive fork sections cover operation checks and removal; faulty plunger and valve units require replacement. The manual warns that turning an anti-dive plunger assembly against its rigid brake line can bend the line.

KZ550-F1 and KZ550-M1 sections add shaft-drive lubrication and propeller-shaft/swingarm removal.
