1992–2001 Honda CR500R Factory Service Manual (P/N 61ML309)

This Honda factory service manual covers the 1992–2001 CR500R, with repair procedures for the two-stroke engine, transmission, chassis and ignition system.

Chapter Bookmarks, Diagram Detail and PDF Format

Navigation and wiring detail: Embedded bookmarks provide access to the main chapters and index. PDF text search is not available. Small wire-color labels in the wiring diagram are best read with zoom.

One printable, English-language PDF contains 213 pages total, including three front-matter pages: the cover, introduction/contents and symbols guide.

Two-Stroke Engine, Suspension and Ignition Service

These selected topics outline the main workshop coverage. The manual also includes silencer glass-wool replacement and optional suspension-spring identification.

• Engine repair: Step-by-step procedures for engine removal, cylinder-head decarbonizing, cylinder and piston inspection, crankcase separation, crankshaft removal and bearing replacement.

• Clutch and shifting: Clutch removal and installation, kickstarter disassembly, gearshift-linkage assembly, transmission shaft assembly and component wear specifications.

• Fuel system: Carburetor disassembly and assembly, float-level and jet-needle settings, temperature/altitude tuning charts, reed-valve service and fuel-system troubleshooting.

• Cooling system: Coolant replacement and air bleeding, radiator removal, water-pump inspection, bearing replacement and mechanical water-seal and oil-seal replacement.

• Chassis and brakes: Separate fork procedures for different versions, shock-absorber overhaul, Pro-Link linkage service, steering-bearing replacement, master-cylinder work, caliper service and brake bleeding.

• Electrical diagnosis: Ignition troubleshooting flowcharts, ICM circuit checks, exciter-coil and pulse-generator tests, ignition-coil inspection, timing checks and a wiring diagram.

This manual suits mechanics familiar with two-stroke teardown and precision measurement; suspension overhaul also calls for the specified service tools and equipment for nitrogen charging.

Engine Teardown and Drivetrain Assembly

The engine-removal section distinguishes work that can be performed in the frame from crankshaft, transmission and shift-fork work requiring engine removal. Cylinder inspection covers bore wear, taper, out-of-round, piston fit and oversize-piston applications.

The cylinder-installation cautions address piston rings snagging in cylinder ports and breaking. Crankcase work includes bearing and oil-seal locations, dedicated removal and assembly tools, and transmission drawings showing gear placement and snap-ring positioning.

Clutch and shifting coverage extends to the lifter mechanism, starter ratchet, return spring, drum shifter and shift forks. Primary reduction and gear-ratio data accompany the drivetrain specifications.

Factory torque tables provide references for the cylinder head, clutch center nut, axles and other assemblies. Combined with the inspection limits, they support parts assessment during teardown and specification checks during reassembly.

Carburetor Tuning and Cooling-System Repair

The carburetor tuning information chart relates air-screw opening, slow jet, needle-clip position and main jet to temperature and altitude. Troubleshooting separates rich and lean running conditions from faults such as intake leaks, restricted fuel flow and crankshaft-seal problems.

Cable and harness routing drawings show how the controls and vent tubes are arranged. Reed-valve instructions distinguish the applicable assembly styles.

Water-pump coverage includes separate checks for coolant and transmission-oil leakage at the inspection hole. Bearing and seal replacement procedures identify dedicated tools, including water seal driver 07945-KA30000. Radiator illustrations show the joint hoses, overflow tube and hose connections; cooling-system tester specifications accompany the service information.

Forks, Pro-Link Suspension and Hydraulic Brakes

Fork sections cover internal disassembly, bushing and seal work, oil filling, air bleeding and reassembly. Their cautions identify possible damage to damping-adjuster needles and the resulting loss of damping performance.

Shock-absorber procedures extend to the reservoir bladder, damper rod, piston ring, valve arrangement and air bleeding. Linkage and swingarm sections address needle and spherical bearings. Support the motorcycle securely for chassis work; shock service involves high-pressure nitrogen.

Brake documentation includes wear-indicator views, hydraulic troubleshooting, pad replacement, front and rear master-cylinder assembly, caliper seals and fluid bleeding.

Ignition Fault-Finding and Wiring References

The no-spark flowchart links checks at the ICM connector with individual component tests. System-location drawings and the wiring diagram identify the engine stop button, ignition coil, exciter coil and pulse generator.

These references help trace an ignition fault through connectors and individual circuits before the ICM is considered for replacement. Additional troubleshooting charts address hard starting, power loss, poor running and handling complaints.

Inspection Limits and Filling Quantities

Examples of the inspection data include cylinder-to-piston clearance of 0.070–0.105 mm, with a 0.12 mm service limit. Connecting-rod big-end side clearance is 0.4–0.8 mm, with a 0.9 mm service limit.

Transmission oil quantities distinguish between 680 cc at an oil change and 750 cc after disassembly.
