Kawasaki H1, H2 & KH500 Shop Manual | 1969–1977

Kawasaki’s original H Series shop manual covers the 1969–1975 H1, 1976–1977 KH500, and 1972–1975 H2, including US and European configurations. This PDF reproduces the 7th Revision dated July 26, 1977.

PDF Search, Bookmarks, and Diagram Detail

Finding text and wiring details: PDF text search is not available. Embedded bookmarks link to the contents, specifications, troubleshooting, index, and selected wiring diagrams. Small labels in the checked wiring diagrams are readable when enlarged; dense connector and switch details require zooming.

The ZIP download contains one printable English PDF. Its 163 pages comprise five opening pages, 131 pages of main workshop content, a 22-page integrated supplement, two conversion/reference pages, and three index pages, all included in the total.

Engine, Injectolube, Chassis, and Ignition Work

The selected coverage below highlights major workshop sections rather than reproducing the full contents. Further topics include automatic fuel-tap inspection and muffler baffle-tube cleaning.

• Engine repair: Step-by-step instructions for engine removal and mounting, top-end disassembly, carbon removal, cylinder and piston inspection, and crankcase separation.

• Clutch and transmission: Clutch service, external gear-shift mechanism repair, transmission disassembly and inspection, selector-fork checks, and kick-starter service.

• Fuel and lubrication: Triple-carburetor inspection, fuel-level testing, idle and throttle-cable synchronization, starter-lever adjustment, and Injectolube adjustment, bleeding, output testing, and component inspection.

• Chassis and brakes: Swingarm, wheel, hub, sprocket, and drive-chain service; steering-stem adjustment; front-fork repair; hydraulic steering-damper checks; and drum- and disc-brake procedures.

• Electrical diagnosis: Separate H1 point and CDI systems and H2 magneto-CDI coverage, with generator, rectifier, regulator, ignition-coil, signal-generator, distributor, and CDI-unit tests.

• Workshop reference: Periodic maintenance guide, master torque table, inspection and wear limits, carburetor settings, electrical test data, exploded drawings, section views, and model-specific wiring diagrams.

This manual is best suited to experienced owners and repair shops equipped to use dial gauges, electrical test equipment, and model-specific service tools.

Engine Inspection and Transmission Differences

The engine chapters explain the four-port scavenge method, then carry the work through cylinder and piston inspection, boring and honing criteria, crankcase service, and crankshaft runout measurement.

Crankshaft coverage: The manual describes common faults and inspection methods and recommends assembly replacement when repair is needed. Press-apart crankshaft rebuilding requires specialized equipment and a high degree of technical skill and is outside the included procedures.

Shift-pattern differences: Kawasaki’s foreword explains that the KH500 was the H1 under a new model name. The 1976 KH500 places neutral between first and second gear, while the through-1975 H-Series pattern places neutral below first.

Carburetor Circuits and Injectolube Variations

Carburetor material explains the pilot, main, starter, float, needle, and throttle-valve circuits, with fault isolation by throttle opening. Separate specification entries distinguish early CDI and non-CDI H1 machines, H1-B, H1-C, H1-D/H1-E, H2/H2-A, and H2-B.

Oil-pump service: Coverage includes pump construction, cable setting, line bleeding, check-valve inspection, and the H2-B pump-performance test. H2-B pump repair is limited to O-ring and shaft-seal replacement; faults in other internal components call for pump-assembly replacement.

Ignition Configurations and Electrical Testing

The separate point, battery-CDI, and magneto-CDI sections help you match diagnostic circuits and test procedures to the ignition fitted to the machine. The main specifications also identify European, French, and Italian differences where applicable.

H1-E supplement: Additional material covers ignition-timing adjustment, regulator/rectifier operation, and dynamo, distributor, CDI-unit, and regulator tests. Testing CDI Unit A requires the Kawasaki Electrotester; a hand tester alone is insufficient.

Wiring diagrams cover the H1 CDI model, European H1 through 1971, and H1 disc-brake model. Later diagrams distinguish H1-E, KH500-A8, and H2-B US and European configurations.

Diagnostic limits: Troubleshooting charts trace starting trouble, misfire, low output, abnormal engine noise, shifting and clutch faults, steering and suspension problems, and brake issues. Advanced H2 ignition tests requiring an oscilloscope are outside the included procedures.

Brake, Suspension, and Chain-Service Boundaries

Disc-brake coverage extends to master-cylinder and caliper disassembly and assembly, pad replacement, brake-line inspection, fluid changes, and bleeding. The supplement adds H1-E/H2-B front-fork construction and repair.

Rear shock absorbers are non-disassembly units, with inspection, adjustment, removal, and replacement covered. The hydraulic steering damper is also replaced as a unit if it leaks.

Drive-chain removal differs between models: the H1 uses a master link, while the H2 chain has no master link.

Illustrations and Workshop Tools

Illustrations include Scavenge Gas Flow Pattern, H Series Crankshaft, and Kick Starter Operation. Master Cylinder and Brake Line Assembly and Front Fork Cross Section show component relationships for brake and suspension work.

The procedures call out a piston-pin puller with adapter A, rotor puller, clutch-hub mounting tool, hook spanner, fuel-level measuring device, TDC finder and dial-gauge adapter, and fork service tools.

Disc-brake service identifies the seal hook as Part No. 56019-111 and the seal/O-ring mounting tool as Part No. 57001-132.

Repair Cautions

The manual warns that incorrect oil-pump cable adjustment can cause piston seizure and that compressed air can distort Injectolube check-valve springs. Reversed battery polarity or connection changes with the engine running can damage CDI components and rectifier diodes, while mineral-base cleaners can deteriorate hydraulic-brake parts.

Brake, steering, and ignition repairs should be performed with the motorcycle securely supported and with the specified test equipment and electrical-isolation precautions.

Selected Clutch-Spring and Crankshaft Inspection Values

Clutch inspection data distinguish H1 spring free length at 36.0 mm standard with a 34.0 mm service limit from H2 springs at 32 mm standard with a 30 mm service limit.

For H1 and H2 crankshaft inspection, the runout table specifies under 0.040 mm as standard and 0.10 mm maximum. These values accompany the dial-gauge inspection material.
