2000 Honda XR650R Factory Shop Manual (P/N 62MBN00)

• Coverage: A 325-page PDF of Honda's February 2000 XR650RY Shop Manual. The manual's type-code table covers ED, E, F, G, U, SA, ND, SW, SD, FI, N, IT, B, H, AR, SP, and D/DK/DM variants. This is the Y-model base publication, not an XR650L manual or a later-year supplement.
• Engine repair depth: Covers cylinder compression testing, decompressor and valve-clearance service, camshaft and cam-chain timing, cylinder-head removal, valve-guide replacement, valve-seat refacing, cylinder and piston inspection, and complete engine removal and installation.
• Drivetrain work: Details clutch-pack inspection, primary-drive gear service, kickstarter and gearshift-cam repair, alternator and flywheel removal, crankcase separation, crankshaft/balancer and bearing replacement, plus transmission disassembly, inspection, and reassembly.
• Fuel, lubrication, and cooling systems: Includes carburetor removal and overhaul, float-level checking, pilot-screw idle-drop adjustment, dry-sump oil-pump and strainer service, check-valve and oil-pipe inspection, cooling-system pressure testing, coolant replacement and air bleeding, thermostat checks, radiator service, and water-pump repair.
• Chassis and hydraulic brake procedures: Provides front-wheel, fork, handlebar, and steering-stem repair; rear-wheel, shock absorber, linkage, and swingarm service; and brake-fluid replacement, air bleeding, master-cylinder, caliper, pad, disc, and brake-pedal procedures.
• Electrical diagnosis and fault isolation: Includes ignition peak-voltage testing, ignition-timing inspection, ICM, coil, alternator, AC regulator and regulator/rectifier checks, lighting and switch diagnosis, five full-page wiring diagrams for ED, DK, and U configurations, and symptom-based troubleshooting charts.

Factory Repair Coverage

The manual is built around the XR650RY's 649 cm³ liquid-cooled, dry-sump SOHC single and 5-speed constant-mesh transmission. The opening section identifies frame, engine, and carburetor number locations, then shows cable and harness routing for the principal market configurations. It also keeps important variant data separate: ED/DK machines use the PE78C carburetor, while the U type uses PE78D; final-drive arrangements, brake-disc specifications, and electrical layouts are likewise separated. That distinction matters when parts, settings, or a wiring schematic are selected for a specific motorcycle.

Routine and competition maintenance schedules lead into valve-clearance inspection, engine-oil and filter service, decompressor adjustment, drive-chain and sprocket work, brake checks, wheel and tire inspection, suspension checks, and steering-head bearing inspection. The related factory tables supply component-specific torque values, service limits, wear measurements, fluid capacities, adjustment data, and electrical test specifications without reducing the manual to a collection of isolated numbers.

The engine chapters support both in-frame top-end repair and engine-out bottom-end work. Cylinder-head coverage includes rocker arms, camshaft bearings, the automatic decompressor, valve springs, guides, seals, and seat refacing. The cylinder and piston section adds bore, taper, ring, piston-pin, and connecting-rod inspection. For deeper repair, the manual covers crankcase separation, crankshaft and balancer removal, crankcase-bearing replacement, transmission inspection, shift forks and shift drum checks, and final crankcase assembly.

Diagnostics, Schematics, and Shop References

Fuel-system repair goes well beyond external adjustment. The carburetor chapter covers the float and jets, throttle valve, air cut-off valve, choke mechanism, float-level measurement, reassembly, and the factory idle-drop procedure for the pilot screw. The lubrication section maps the dry-sump circuit and documents both oil-pump rotor sets, the crankcase and frame/down-tube strainer screens, the check valve, and the external oil pipes. Cooling-system coverage includes the system flow pattern, coolant gravity chart, radiator-cap and system-pressure inspection, replacement and air bleeding, thermostat testing, radiator removal, water-pump mechanical-seal inspection, and reserve-tank service.

The chassis chapters include full fork disassembly, bushing and seal inspection, damper-rod service, fork-fluid filling, air bleeding, oil-level setting, and damping adjustment. Rear-suspension repair extends to shock-spring removal, reservoir bladder replacement, damper disassembly, piston and rod-guide inspection, shock-oil filling and bleeding, nitrogen charging, linkage bearings, and swingarm service. Hydraulic brake coverage handles both master cylinders and calipers rather than stopping at pad replacement.

Useful visual references include the lubrication-system cutaway, cooling-system flow pattern, cable and harness routing views, crankcase-emission schematic, major exploded assembly views, and the market-specific wiring pages. Honda tool references include the 07401-0010000 carburetor float-level gauge, 07HMH-MR10103 drive-chain tool set, 07757-0010000 valve-spring compressor, 07725-0040000 flywheel holder, and 07HGJ-0020100 peak-voltage adapter.

Important Repair Notes

Two XR650R repair traps are called out clearly. Installing the engine-oil filter backward can cause severe engine damage, and the crankcase halves must not be forced together when a shaft, dowel, or internal part is misaligned. The rear shock contains high-pressure nitrogen, while the fuel and hydraulic brake sections require careful control of flammable fuel, brake-fluid contamination, and system bleeding. Use the manual's factory warnings, specified tools, and final operational checks whenever these repairs are performed.
