1999–2002 Yamaha YZF-R6R / R6SR / R6RC / R6SRC Service Manual (P/N LIT-11616-16-45, 5SL-28197-10)

This factory service publication covers the 1999–2002 Yamaha YZF-R6R, YZF-R6SR, YZF-R6RC, and YZF-R6SRC, including the 5SL3, 5SL4, 5SL7, and 5SL8 configurations. Yamaha publication identifiers: LIT-11616-16-45 and 5SL-28197-10.

Delivered as a 433-page PDF in one file, covering all nine manual chapters.

• Engine repair: Engine removal, cylinder-head and crankcase disassembly, valve service, camshaft timing, and crankshaft and piston inspection.

• Transmission and clutch: Internal gearshaft inspection, shift-drum and shift-fork checks, clutch-plate inspection, and reassembly.

• Fuel injection: ECU self-diagnosis, diagnostic mode, fail-safe actions, throttle-body synchronization, and fuel-pump, pressure-regulator, and throttle-position-sensor testing.

• Cooling and lubrication: Water-pump overhaul, thermostat and radiator-cap testing, oil-cooler service, and oil-pump inspection.

• Brakes and chassis: Hydraulic brake bleeding, master-cylinder and caliper repair, front-fork rebuilding, steering-head service, and swingarm inspection.

• Electrical troubleshooting: Ignition, starting, charging, lighting, signaling, and radiator-fan circuit diagnosis, with wiring diagrams and starter-motor repair.

Written primarily for Yamaha dealers and their qualified mechanics, this manual assumes a working knowledge of mechanical service and motorcycle repair techniques.

Engine Overhaul and Service Specifications

Periodic maintenance charts cover emission controls and general lubrication. Valve-clearance procedures include pad-selection tables; engine checks cover compression and oil pressure.

Internal engine repair extends to valve guides and seats, piston rings, and crankshaft and connecting-rod bearings. Bearing-selection charts use component markings and color codes, with wear limits, clearance specifications, torque tables, and fluid-capacity data available throughout the manual.

The transmission section includes gear-dog condition and shaft-runout checks. Clutch assembly illustrations distinguish brown and purple friction plates and different clutch-plate thicknesses.

Camshaft assembly: Uneven cap-bolt tightening can damage the cylinder head, caps, and camshafts; the manual addresses this in its installation precautions.

Fuel Injection and California Equipment

The FI overview explains ECU-controlled fuel metering and air-induction control. Fault-code tables connect reported faults to sensor, harness, and connector checks, with factory test values, reinstatement methods, and fault-history information.

These checks help a technician distinguish a failed sensor from a wiring or pressure-sensor hose fault before choosing a repair.

California-specific coverage includes the evaporative-emissions canister and hose routing. Specifications distinguish California and non-California throttle-body identification marks and ignition settings.

The throttle-body section covers injector inspection, fuel-pressure testing, and TPS adjustment, with a specific caution against internal throttle-body disassembly. The specified fuel-pressure adapter is 90890-03176 / YM-03176.

Cooling, Brakes, and Suspension

Water-pump procedures include mechanical-seal replacement and impeller-shaft inspection.

Brake sections cover piston seals and hydraulic components, including Yamaha's warning that solvent cleaning can swell and distort caliper piston seals.

Front-fork coverage includes damper-rod service, bushing and seal replacement, and oil-level setup. The special-tool list identifies damper rod holder 90890-01473.

Rear-shock coverage includes removal, inspection, linkage service, and spring-preload and damping adjustments. Yamaha cautions against opening the pressurized shock absorber or gas cylinder.

Electrical Diagnosis and Diagram Reference

Starting circuit cut-off operation and relay tests support no-crank diagnosis; charging checks cover the stator and rectifier/regulator. The generator section also documents rotor removal and installation.

Reference illustrations include fuel-injection wiring, starting-system circuit diagrams, cable routing, cooling system diagrams, the engine oil lubrication chart, and air-induction system diagrams. Exploded views accompany disassembly tables, while troubleshooting charts and fail-safe tables support fault isolation.

If you lack the required tools or experience, consult a certified motorcycle mechanic for critical engine or braking system adjustments.

File Format and Readability

The total includes 16 front-matter pages, 412 chapter pages, two wiring-legend pages, one back cover, and two full wiring-diagram sheets: one black-and-white and one color. All are already included in the stated page count.

Text search: The main chapters have searchable text. The front cover and labels on the full wiring-diagram sheets do not.

Navigation: Nine embedded bookmarks lead to chapter listings in the table of contents; two open the full wiring diagrams.

Wiring readability: Small component numbers, connector details, and wire-color codes require zooming.
