Honda CMX450C Rebel Cruiser 1986–1987 Service Manual (P/N 61MM201)

This three-PDF reference set covers the 1986-1987 Honda CMX450C Rebel and combines the model-specific factory service manual with Honda's 1995 Common Service Manual and an illustrated parts-reference file. The CMX450C manual is the core repair source for the 447 cc air-cooled parallel twin, five-speed-plus-overdrive transmission, chain final drive, and model-specific chassis and electrical systems. It distinguishes the standard VE24A carburetor configuration from the VE28A California configuration with evaporative-emission controls. The material is suited to experienced technicians and advanced DIY owners who can use vacuum and pressure gauges, electrical test equipment, and the specified service tools.

• 781 PDF pages total - 243-page 1986-1987 CMX450C Service Manual; 440-page Honda Common Service Manual dated March 1995; and a 98-page illustrated parts reference.
• Engine and transmission repair - engine removal and installation, cylinder-head and valve service, cylinder and piston inspection, clutch and oil-pump work, crankcase separation, crankshaft bearing selection, balancer timing, and five-speed-plus-overdrive transmission disassembly and reassembly.
• Fuel and emissions procedures - dual CV carburetor removal, separation, cleaning, reassembly, synchronization, pilot-screw and high-altitude adjustment, plus California-only canister, purge-control-valve, and vacuum-hose checks.
• Chassis and brake service - spoke and wheel work, wheel balancing, fork disassembly and seal replacement, steering-stem bearing replacement and preload, swingarm and shock service, rear drum-brake repair, and front hydraulic-brake bleeding and overhaul.
• Electrical diagnosis - charging-voltage and leakage tests, regulator/rectifier and charging-coil inspection, CDI ignition checks, pulse-generator and exciter-coil tests, starter-motor and relay repair, clutch-diode testing, and switch continuity checks.
• Factory reference data - component torque tables, lubrication and capacity data, oil-pressure and compression testing, wear limits, bearing and gear-selection data, suspension and brake specifications, and electrical test values.

CMX450C Powertrain and Chassis Coverage

The model-specific manual begins with identification points, specifications, special tools, cable and harness routing, and U.S. emission-control information. Its maintenance section covers valve-clearance inspection, balancer-chain adjustment, carburetor synchronization, cylinder-compression testing, drive-chain service, brake inspection, suspension checks, and steering-head bearings. Each major repair chapter opens with service information and troubleshooting before moving into removal, inspection, assembly, and installation coverage.

The tool chart identifies the vacuum gauge 07404-0030000, pilot-screw wrench 07908-4220201, clutch-center holder 07923-KE10000, steering-stem socket 07916-3710100, and fork-seal driver 07747-0010100, along with bearing, valve-guide, and shock-compressor tooling.

Engine work goes well beyond tune-up material. The cylinder-head chapter includes camshaft and rocker-arm inspection, valve-guide replacement, valve-seat inspection and grinding, head assembly, and cam timing. The lower-end chapters cover piston and ring service, oil-pump inspection, crankshaft and connecting-rod bearing selection, starter-clutch work, transmission gear and dog inspection, shift forks and drum, balancer installation, and final crankcase assembly.

Chassis coverage follows the same repair-oriented structure. The front end includes handlebar removal, spoke replacement, hub and bearing service, fork teardown, seal and bushing installation, steering races, and steering-head preload. Rear chapters cover wheel and driven-flange service, rear brake disassembly, shock-absorber inspection, swingarm pivot bearings, and rear fender and seat removal. The hydraulic-brake section adds fluid replacement and bleeding, pad and disc inspection, caliper overhaul, and master-cylinder disassembly and assembly.

Diagrams and Diagnostic Support

The visual references include Cable & Harness Routing views, the California Vacuum Hose Routing Diagram, the Battery/Charging System schematic, the Ignition System schematic, the Electric Starter interlock circuit, and the complete Wiring Diagram. A separate troubleshooting section traces low power, fuel-flow problems, starting faults, charging complaints, and abnormal wheel or suspension behavior. The parts-reference PDF supplements these drawings with exploded assemblies, reference numbers, quantities, and Honda part numbers for major engine, fuel, chassis, and electrical groups.

How the Three PDFs Work Together

The 243-page CMX450C manual contains the motorcycle-specific repair procedures and specifications and carries Honda code 61MM201, dated October 1986. The 1995 Common Service Manual explains system theory, general inspection methods, bearing and fastener practices, engine testing, carburetion, chassis work, and electrical fundamentals across Honda motorcycles, scooters, and ATVs. It is supplemental: it expressly directs the reader back to the model-specific manual for adjustments, maintenance, and repair information. Its cooling-system and V-Matic sections do not indicate that those systems are fitted to the CMX450C.

The parts-reference PDF is an illustrated lookup aid rather than a substitute for the service procedures. Its price column should not be treated as current availability or current pricing.

Factory Cautions That Matter

The cylinder-head chapter flags the camshaft-holder mating and bearing surfaces as vulnerable during installation and warns against allowing the cam chain to jam while timing is checked. The brake chapter identifies inverted master-cylinder cup lips as an assembly error that can compromise hydraulic sealing. Factory safety material also covers engine-running work, gasoline, battery electrolyte, brake-fluid contamination, and brake dust; carburetor synchronization and other running tests require proper shop ventilation.
