Honda XR650R 2000 Factory Shop Manual

Honda's February 2000 XR650RY Shop Manual covers the 2000 XR650R in ED, U, and D (DK/DM) area types. This is the Y-model base publication, not an XR650L manual or a later-year supplement.

PDF Bookmarks and Wiring Diagram Viewing

Navigation and small labels: Embedded PDF bookmarks provide access to chapters and individual procedures. PDF text search is not available. Small wiring-diagram labels are readable with magnification; rotating the sideways wiring pages also makes them easier to follow.

One printable, 325-page PDF, including the cover, three introductory pages, two index pages, eight memo pages, and one blank page.

Engine Overhaul, Chassis Service, and Electrical Diagnosis

The following selected topics show the manual's repair coverage. Other examples include fuel-tank and exhaust-system removal and spark-arrester cleaning.

• Maintenance: Routine and competition schedules, valve-clearance and decompressor adjustment, oil and filter service, chain and sprocket work, and wheel, tire, suspension, and steering-head checks.

• Engine repair: Step-by-step procedures for compression testing, cylinder-head removal, valve-guide replacement, valve-seat refacing, camshaft and cam-chain timing, and cylinder and piston inspection.

• Drivetrain: Clutch, primary-drive gear, kickstarter, and gearshift-cam service; flywheel removal; crankcase separation; crankshaft, balancer, and bearing replacement; and transmission disassembly and reassembly.

• Fuel and lubrication: Carburetor overhaul, float-level checking, pilot-screw idle-drop adjustment, dry-sump oil-pump and strainer service, check-valve inspection, and external oil-pipe work.

• Cooling system: Pressure testing, coolant replacement and air bleeding, thermostat inspection, radiator service, water-pump assembly replacement, and reserve-tank removal and installation.

• Chassis and brakes: Front-wheel, fork, handlebar, and steering-stem repair; rear-wheel, shock, linkage, and swingarm service; hydraulic bleeding; and master-cylinder, caliper, pad, disc, and brake-pedal procedures.

• Electrical diagnosis: Ignition peak-voltage and timing checks, alternator and regulator tests, lighting and switch diagnosis, market-specific wiring diagrams, and symptom-based troubleshooting charts.

Honda wrote this manual for readers with basic knowledge of Honda motorcycle, scooter, or ATV maintenance. Standard workshop procedures and safety fundamentals are assumed.

Market Variants and Diagnostic References

ED/DK machines use the PE78C carburetor, while the U type uses PE78D. Final-drive arrangements, brake-disc specifications, and electrical layouts are also separated. That distinction matters when parts, settings, or a wiring schematic are selected for a specific motorcycle.

Frame, engine, and carburetor identification views accompany the cable and harness routing illustrations. Five wiring-diagram pages cover ED, DK, and U configurations, including language variants.

Other visual references include the lubrication-system cutaway, cooling-system flow pattern, coolant gravity chart, crankcase-emission schematic, and exploded assembly views.

Ignition troubleshooting compares signals at the ICM and component connectors to distinguish harness faults from exciter-coil or ignition-pulse-generator faults. The ignition-coil tests use the 07HGJ-0020100 peak-voltage adapter with a digital multimeter. Separate AC regulator and regulator/rectifier procedures cover the lighting circuits.

Top-End Repair and Engine-Out Work

The liquid-cooled SOHC single is covered through both in-frame top-end repair and engine-out bottom-end work. Cylinder-head procedures include rocker arms, camshaft bearings, the automatic decompressor, valve springs, guides, seals, and seat refacing.

Cylinder and piston inspection covers bore wear, taper, rings, piston pins, and connecting-rod measurements. Factory tables provide the related torque values, service limits, fluid capacities, and adjustment data.

Crankshaft, balancer, and internal transmission service require engine removal and crankcase separation. Transmission inspection extends to gear engagement dogs, bushings, shift forks, and the shift drum. The crankcase assembly warning addresses damage risks from forcing misaligned case halves together.

Honda tool references include the 07757-0010000 valve-spring compressor and 07725-0040000 flywheel holder.

Carburetor, Oil Pump, and Cooling Service

Carburetor coverage extends to the float and jets, throttle valve, air cut-off valve, choke mechanism, and factory pilot-screw adjustment. Float inspection uses the 07401-0010000 float-level gauge.

Lubrication procedures cover both oil-pump rotor sets, crankcase and frame/down-tube strainers, the check valve, and external oil pipes. An oil pump beyond its service limits is replaced together with the right crankcase cover. The filter-service warning explains that installing the oil filter backward can cause severe engine damage.

Cooling diagnosis includes radiator-cap testing and water-pump mechanical-seal leak inspection. The water pump is replaced as an assembly, rather than disassembled for internal repair, when its seal is defective or the pump is damaged.

Forks, Rear Shock, and Hydraulic Brakes

Fork procedures extend to bushings, seals, damper rods, fluid filling, air bleeding, oil-level setting, and damping adjustment. Rear-shock work includes spring removal, reservoir bladder replacement, damper disassembly, piston and rod-guide inspection, oil filling and bleeding, and nitrogen charging.

Linkage and swingarm procedures include needle-bearing replacement. Drive-chain replacement uses the 07HMH-MR10103 drive-chain tool set. Hydraulic brake coverage handles both master cylinders and calipers rather than stopping at pad replacement.

The rear shock contains high-pressure nitrogen, while fuel and hydraulic brake work 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.

Selected Float-Level and Thermostat Test Data

Carburetor inspection specifies a float level of 16.0 mm (0.63 in), with the float valve just contacting the float arm lip.

Thermostat testing specifies an opening temperature of 80–84°C (176–183°F) and a minimum valve lift of 8 mm (0.3 in) at 95°C (203°F).
