1987–2002 Kawasaki KL650 / KL500 Factory Service Manual Supplement (P/N 99924-1080-58)

The 1987–2002 Kawasaki KL650/KL500 Service Manual Supplement, P/N 99924-1080-58, documents model-specific maintenance and repair information. It must be used with the KLR600 base Service Manual, P/N 99924-1050-01, which is not included.

• Engine service: Engine removal and installation, camshaft-chain tensioner installation, cylinder-head tightening sequences, piston-ring identification, and balancer assembly notes.

• Fuel and emissions: Carburetor jetting tables, U.S. high-altitude modifications, air-cleaner service, fuel-tank vent inspection, and California evaporative-system hose routing.

• Cooling system: Coolant-flow diagrams, radiator removal notes, water-pump assembly differences, and thermostat and radiator-cap specifications.

• Brakes and suspension: Front caliper assembly details, master-cylinder disassembly notes, brake-disc runout inspection, fork guide-bush installation, and rear-shock removal.

• Electrical diagnosis: Regulator/rectifier tests, model-specific CDI resistance tables, starter-motor inspection, starter-clutch checks, and charging, ignition, and starter wiring diagrams.

• Model updates: Dedicated KL650-A14/A15 and KL650-A16 chapters document revised specifications, assembly illustrations, wiring details, and maintenance information.

Written primarily for trained mechanics in an equipped shop, the supplement also supports owners performing basic maintenance and repair who understand mechanical principles, tools, and workshop procedures.

Engine and Drivetrain Service

The engine-removal flowchart identifies the components and connections involved in removing the engine unit. Separate right- and left-side removal charts show access relationships around the clutch, magneto, starter drive, and balancer mechanism.

Cylinder-head installation notes provide a tightening sequence, while piston-ring cross sections distinguish the top and second rings. The balancer section identifies magneto holder 57001-1184 for the front balancer-weight fastener.

Valve-clearance adjustment and most internal engine and transmission procedures refer to the base manual. This supplement supplies the related model-specific service data, exploded views, gear ratios, and wear limits; it does not replace those underlying procedures.

Fuel Delivery and Cooling Details

The carburetor tables distinguish KL500, early KL650, and later KL650 settings, including market-specific jetting. California vacuum and breather hose drawings identify connections between the fuel tank, liquid/vapor separator, canister, and intake system. Carburetor disassembly relies on the base manual.

The fuel-cap inspection section warns that compressed air can damage and obstruct the cap’s vent labyrinth. Air-cleaner instructions address element sealing and drain-tube placement.

The Coolant Flow Chart shows circulation through the radiator, pump, cylinder, and thermostat. Water-pump notes explain the supplement-specific impeller shim arrangement; mechanical-seal disassembly and inspection refer to the base manual.

Always ensure your workspace is well-ventilated and that you wear appropriate protective gear when handling fuel system components or maneuvering heavy chassis parts.

Brake, Wheel, and Suspension Work

Brake coverage includes front pad removal, caliper assembly details, master-cylinder component views, rear-pedal adjustment, and disc runout measurement. Rear-wheel removal, front-wheel balancing, and drive-chain adjustment are also documented.

Fork-service additions identify outer-tube weight 57001-1218 and oil-seal driver 57001-1219. Rear-shock instructions cover removal and preload selection, with a spring-preload and damper-setting table. Steering-stem bearing service and Uni-Trak bearing inspection refer to the base manual; the supplement supplies associated illustrations, tools, and sleeve wear limits.

Charging, Ignition, and Starting Faults

Separate CDI resistance tables distinguish KL500/KL650-A1–A3 from KL650-A4 onward. Their terminal and meter-polarity assignments help mechanics select the correct diagnostic reference before judging a CDI unit.

Regulator/rectifier testing includes terminal views and circuit-test diagrams. Starter coverage extends to brushes, commutator, armature, insulation checks, relay testing, and starter-clutch operation. The starter-removal caution explains that striking the shaft or housing can damage the motor.

The KL650-A14/A15 wiring diagram identifies later lighting changes alongside wire-color codes and switch-connection tables. The troubleshooting appendix adds starting-fault causes to the base manual’s diagnostic coverage.

Cooling and Electrical Specification Samples

The KL650/KL500 cooling-system table lists a total coolant quantity of 1.3 L alongside radiator-cap and thermostat specifications.

Electrical service data specify a 0.8–0.9 mm gap for the listed spark plugs, including the NGK DPR8EA-9. The charging-system reference gives a stator-coil resistance of 0.3–1.0 Ω between yellow leads at the disconnected magneto connector.

PDF Bookmarks and Wiring Detail

Navigation and diagram reading: Embedded bookmarks link to chapters and model-update sections. PDF text search is unavailable. Small wire-color codes and component labels in the main wiring diagrams require zooming.

One printable, English-language 130-page PDF includes 101 pages in chapters 1–15, the 15-page KL650-A14/A15 supplement, the 6-page KL650-A16 supplement, seven opening pages including the cover, and one rear model-application page.
