Honda XR400 OEM Service Manual (P/N 62KCE00)

Before ordering, check the model carefully: this is a Honda XR250R(T) manual for the 249 cc engine, not an XR400R manual. The November 1995 factory publication is in English and is organized as 14 PDF files totaling 300 pages.

• Model and configuration coverage: Identifies the ED European-direct-sales, U Australian, and D general-export area types, including DK/DM references, plus frame, engine, carburetor, and color-label identification locations.
• Engine and drivetrain repair: Covers engine removal and installation, cylinder-head and valve work, camshaft timing, cylinder and piston inspection, clutch and kickstarter service, crankcase separation, crankshaft and balancer work, and transmission disassembly and assembly.
• Fuel and lubrication systems: Details fuel-tank and air-cleaner components, carburetor removal and overhaul, float and jet inspection, pilot-screw adjustment, oil-pump service, oil-strainer access, and oil-pipe and passage inspection.
• Chassis and suspension work: Includes front- and rear-wheel service, hub bearings, fork disassembly and assembly, steering-stem and head-bearing work, swingarm and linkage repair, and full rear-shock disassembly, oil filling, bleeding, and nitrogen charging.
• Brake and electrical diagnosis: Covers brake-fluid replacement and bleeding, pads, discs, calipers, master cylinders, ignition peak-voltage testing, charging and lighting checks, switch continuity tests, and turn-signal fault isolation.
• Factory workshop data: Provides service limits, component-specific torque tables, clearances, fluid specifications, maintenance schedules, Honda special-tool listings with tool numbers, cable and harness routing views, wiring diagrams, and system-based troubleshooting charts.

Working on motorcycles carries inherent risks, so keep the machine securely supported and the workspace properly ventilated. The rear shock is nitrogen-pressurized, while brake, fuel, spring, and ignition work require suitable isolation and service equipment. Double-check all torque values, clearances, oil levels, and test pressures against the factory tables before turning a wrench.

Engine, Fuel, and Drivetrain Repair Depth

The top-end chapters cover the cylinder-head cover, camshaft, valves and springs, valve guides and seats, cylinder, piston, and rings. Lower-engine and drivetrain sections document clutch and primary-drive service, kickstarter and gearshift work, alternator removal, crankshaft and balancer inspection, crankcase-bearing replacement, and transmission overhaul.

Timing-mark illustrations support camshaft installation, while the transmission section uses exploded mainshaft and countershaft views and identifies the shift-fork positions. The crankcase chapter also calls out a damage risk that matters during repair: the case halves must not be forced together or drawn together with the case bolts when an assembly fault leaves a gap.

The fuel section includes carburetor disassembly and assembly, float-level and jet checks, choke and throttle-valve components, pilot-screw adjustment, and intake-leak diagnosis. One manual-specific caution concerns the pilot-screw seat, which can be damaged if the screw is tightened hard against it. Because the engine is air-cooled, this publication has no radiator, coolant, or water-pump repair chapter.

Suspension, Brakes, and Electrical Systems

Fork coverage includes removal, internal disassembly, guide and seal service, wear inspection, oil filling and level setting, reassembly, and installation. The rear-suspension section reaches into the remote-reservoir shock, bladder, damper rod, piston components, internal oil bleeding, gas charging, linkage bearings, spherical bearings, and swingarm service.

The brake chapter addresses both hydraulic disc systems, including fluid replacement, air bleeding, pad and disc inspection, caliper overhaul, master-cylinder repair, and the front lever and rear pedal assemblies.

Electrical sections cover the ignition control module, ignition coil, pulse generator, alternator, AC regulator, regulator/rectifier, lighting, horn, brake-light switches, handlebar switches, and turn-signal relay. Diagnostic support includes ignition troubleshooting, peak-voltage test procedures, wire-harness checks, switch continuity tables, lighting-system flowcharts, and separate full wiring diagrams for ED, DK, and U types.

Diagrams, Troubleshooting, and Manual Scope

Representative illustrations include the lubrication-system sectional view, carburetor exploded assembly, camshaft timing diagrams, transmission shaft exploded views, rear-shock damper and reservoir views, and the type-specific electrical schematics. The final troubleshooting section organizes fault isolation around hard starting, low power, poor idle and low-speed performance, high-speed performance problems, and poor handling.

This is model-specific factory repair information for technicians and experienced owners. It assumes basic Honda motorcycle service knowledge and does not teach standard workshop methods or general safety principles; its scope is the component-level repair procedures, inspection criteria, test data, and assembly references for the covered XR250R configuration.
