Kawasaki KLR600 1984–1994 Service Manual Set (P/N 99924-1050-01)

The supplement contains procedures and specifications that changed for, or are unique to, the electric-start models. Unchanged service operations remain in the base manual, so both publications are required for a complete KL600-B repair reference.

PDF Search, Bookmarks, and Diagram Detail

Search and wiring detail: The base manual has partially searchable OCR text and chapter bookmarks. The supplement has page-number bookmarks but no PDF text search. Small wiring labels require zooming; some labels in the supplement’s full wiring diagram remain difficult to read when enlarged.

The ZIP download contains two printable English PDFs totaling 221 pages, including three cover pages and 10 preliminary reference, safety, and foreword pages.

Engine Overhaul and Electric-Start Service

The following selected coverage highlights outline the main workshop sections. Additional topics include general lubrication and US-model spark-arrester cleaning.

• Engine repair: Cylinder-head and valve work, camshaft and cam-chain service, KACR inspection, cylinder and piston service, engine removal, crankcase splitting, crankshaft work, transmission service, and balancer timing.

• Fuel system: Keihin CVK40 inspection and adjustment, service fuel-level checks, market-specific and high-altitude calibration, air-cleaner maintenance, and California evaporative-emissions service.

• Cooling system: Coolant draining, filling and air bleeding, leak and pressure testing, radiator and fan removal, thermostat checks, water-pump repair, and the carburetor-heater layout.

• Chassis and controls: Wheels and tires, final drive, front and rear brakes, steering bearings, front fork, Uni-Trak suspension, cables, instruments, frame routing, and electric-start-model throttle adjustment.

• Electrical diagnosis: Battery, charging and CDI ignition systems, starter clutch, starter motor, relays, safety interlocks, switches, lighting, gauges, cooling fan, continuity tests, and component resistance checks.

The material is written primarily for trained motorcycle mechanics working in a properly equipped shop. An experienced owner can also use it for basic maintenance and repair, provided they understand standard workshop practices and tool use; more involved work requires the specified equipment and mechanical knowledge.

Top-End, Bottom-End, and Lubrication Work

Step-by-step procedures cover cam-chain tensioner installation, valve-clearance adjustment, engine removal, crankcase separation, and transmission assembly. The valve section includes shim-selection charts, valve-seat repair, installed-height checks, and valve-to-guide inspection.

The Kawasaki Automatic Compression Release section distinguishes starting-related faults from compression-release problems while running. Cylinder compression testing, piston-ring identification, camshaft bearing-clearance checks, oil-pressure testing, and balancer-chain timing support deeper engine diagnosis.

The supplement changes the tensioner installation procedure and piston-ring orientation information. Crankshaft disassembly and reassembly require a shop with the necessary precision tools and equipment.

Carburetor Calibration and Cooling Repairs

Fuel and emissions: Carburetor removal and disassembly instructions accompany pilot-screw, jetting, float-height, and service fuel-level data. The supplement separates early and later B-series calibration, while California-specific information covers the canister, liquid/vapor separator, and hose connections.

Cooling: Water-pump mechanical-seal installation includes impeller-shim information, with revised assembly details in the supplement. The 1994 carburetor-heater illustration identifies its coolant connections, filter, and valve.

Brakes, Suspension, and Reassembly

Hydraulic front-brake coverage includes caliper and master-cylinder disassembly, fluid replacement, bleeding, and disc inspection. Rear drum-brake information covers shoe replacement, cam-lever positioning, pedal adjustment, and brake-light switch adjustment.

Fork service extends to internal disassembly, guide-bush inspection, and oil-seal replacement. Uni-Trak coverage includes linkage bearings, sleeves, lubrication, spring removal, preload, and damping adjustment; the nitrogen-filled shock damper is not treated as an internal rebuild.

Electrical Fault Isolation and Workshop Illustrations

The starter troubleshooting guide distinguishes a motor that does not rotate from one that runs without turning the engine. Starter-clutch checks, brush and commutator inspection, relay testing, and interlock diagrams help trace the fault to the relevant assembly.

Illustrations include the left-side part-removal flowchart, piston-ring cross sections, water-pump mechanical-seal section, starter-clutch and starter-motor exploded view, charging-system schematic, and electric-starter circuit diagram. Cable, hose, and wiring-routing views support reassembly.

Reference tables provide tightening torques, wear limits, fluid data, and electrical test values. Tool callouts identify the fuel-level gauge, crankshaft installing jig, magneto holder and puller, and Kawasaki electrical testers.

Repair cautions: Oil or dirt on the magneto rotor taper, or incorrect tightening, can allow the rotor bolt to loosen and cause serious damage. The starter-motor section also warns that impact on its shaft or housing can damage the motor.

The starter circuit includes a battery-positive lead that remains live with the ignition switched off, so disconnected leads must be protected from contact with the chassis.

A Preview of Valve and Thermostat Specifications

Cold valve-clearance specifications are 0.10–0.20 mm for the inlet valves and 0.15–0.25 mm for the exhaust valves. The adjustment section pairs these ranges with shim-selection charts.

For cooling-system diagnosis, the thermostat inspection specifies an opening temperature of 69.5–72.5°C (157–162°F). The same chapter supplies thermostat-lift and radiator-cap relief-pressure data.
