Honda CBX Shop Manual Set, 1979–1982 (P/N 6142202)

Each shop manual pairs a base edition with a model-year addendum. Use the addendum for changes to the later model and the corresponding base manual for procedures the addendum leaves unchanged.

Wheel and wheel-bearing service are covered. Honda refers tubeless tire repairs to a separate Tubeless Tire Manual (No. 6141550), which is outside this set.

PDF Layout and Wiring Diagram Detail

Search, bookmarks, and diagram labels: Both PDFs have printed contents pages, with no text search or embedded bookmarks. Small wire codes and connector labels in the 1979–1980 diagrams are readable at higher zoom. Some of those labels remain hard to distinguish in the 1981–1982 main wiring diagram even when enlarged.

The ZIP contains two printable English-language PDFs totaling 631 pages. The total includes both covers and the addenda already bound into the manuals: 39 pages for the ’80 Addendum and 9 pages for the ’82 Addendum.

CBX Engine, Chassis, and Electrical Service

These selected service topics show the range of the manuals. The chapters also include crankcase emission-control routing and switch-continuity charts.

• Cylinder head: DOHC four-valve head service covers camshaft timing, valve-guide and seat work, and shim selection. The cylinder and piston chapter includes bore and ring inspection.

• Carburetors: Rack disassembly and vacuum synchronization are documented alongside accelerator-pump service, air cutoff valve inspection, and fuel-line diaphragm testing on applicable models.

• Clutch and transmission: The manuals detail wet multi-plate clutch service, gear and shaft inspection, and starter-clutch repair in the crankshaft and primary-shaft chapter.

• Steering and suspension: Front-fork overhaul, steering-head bearing adjustment, swingarm service, and rear-shock work cover the chassis changes documented across the two editions.

• Hydraulic brakes: Service chapters cover master-cylinder and caliper rebuilding, disc and piston inspection, brake bleeding, and troubleshooting for poor braking or brake drag.

• Electrical diagnosis: Wiring diagrams and Cable & Harness Routing drawings accompany transistorized ignition tests, charging-system checks, and starter-motor inspection and overhaul.

The manuals suit readers familiar with standard workshop procedures and equipped to use the specified measuring and service tools.

Engine Access and Bottom-End Inspection

The engine removal chapters help you plan access by separating in-frame jobs such as clutch service from cylinder-head and piston work with the engine tilted forward, and from work requiring complete removal. The valve and camshaft sections flag a specific risk: mishandling the tachometer drive can break the No. 4 camshaft holder and require cylinder-head assembly replacement.

Crankcase and transmission coverage includes shift-fork and shift-drum inspection. The crankshaft chapter pairs bearing color codes with Plastigauge clearance checks. The earlier edition separates primary-shaft procedures by engine serial number, including changes to sprocket indexing and the collet ring nut.

The Engine Lubrication Diagram shows the dual-pump oil circuit and cooler. The service chapters pair oil-pressure testing with pump-rotor inspection and relief-valve service. Reference tables give component torque values, fluid capacities, and wear limits. Tool listings identify the CBX Special Tool Set No. 07900-4220101 and carburetor throttle wrench No. 07908-4220100.

Carburetor Identification and Calibration

The fuel-system tables identify VB60A carburetors for 1979, VB62A for 1980, and VB64A for 1981–1982. Rack service covers separation into two banks of three and the throttle and choke linkages. Tube Routing illustrations help identify the connections around the assembly.

The synchronization procedure uses the fixed No. 4 reference carburetor. The manuals also document fast-idle settings, pilot-screw idle-drop adjustment and limiter caps where applicable, and a U.S. high-altitude adjustment in the later edition.

Suspension, Brakes, and Touring Bodywork

The ’80 Addendum details air-assisted front forks and adjustable F.V.Q. twin shocks. The later manual covers the front-fork air connection and Pro-Link rear suspension, including shock oil-seal replacement and linkage-bushing inspection. Its brake chapters cover dual-piston calipers and ventilated front discs.

Touring-bodywork procedures cover fairing disassembly, windshield replacement, and saddlebag and stay removal. The ’82 Addendum adds fuel-strainer service, seat and grab-rail removal, and rear-shock mounting-bushing lubrication.

Ignition, Charging, and Suspension Warning Tests

Ignition troubleshooting separates faults by cylinder pair and provides checks for pulse generators, spark units, and coils. Alternator service covers the brushes, rotor, stator, and drive coupling, with test tables for the regulator and rectifier.

In the later manual, Rear Suspension Warning System flowcharts distinguish faults in the pressure sensor, control unit, wiring, and speedometer input.

Always double-check torque values against the applicable model-year specifications and keep your workspace well-ventilated when handling fuel system components.

Valve Clearance and Compression Test Preview

For cold intake and exhaust valves, the 1979 base manual lists 0.08 mm with a +0.05/−0.02 mm tolerance. The 1980–1982 specifications express the same limits as 0.06–0.13 mm. The valve service sections pair these limits with shim selection.

Both manuals list 170 ± 14 psi for the warm-engine cranking compression test with the throttle and choke fully open. The later manual also specifies a fully charged battery for the test.
