Yamaha YZF-R6V 2006 Service Manual (P/N 2C0281972006)

Yamaha’s service manual for the 2006 YZF-R6V (YZFR6V) covers scheduled maintenance, troubleshooting, and engine and chassis repair. This is the Second Edition, May 2007, P/N 2C0281972006.

Searchable PDF and Wiring Detail

Search and diagram navigation: Searchable text and embedded chapter and component bookmarks support navigation. Small connector labels and wire-color codes on dense wiring pages require zooming.

One printable English PDF contains 437 pages, including the cover, four introductory pages, and the publisher’s back page.

Engine, Chassis, and YCC-T Service

These content highlights are a selection from the manual; other topics include multi-function meter settings and air-induction-system checks.

• Maintenance and specifications: Periodic service charts, engine and chassis torque tables, lubrication points, wear limits, and electrical test specifications.

• Engine repair: Engine removal, valve-clearance adjustment, camshaft timing, cylinder-head service, piston inspection, and crankshaft bearing checks.

• Clutch and transmission: Clutch disassembly, plate inspection, assembly-width adjustment, transmission reassembly, and shift-fork and shift-drum inspection.

• Fuel injection and EXUP: Throttle-body synchronization, position-sensor adjustment, primary and secondary injector checks, fuel-pump service, and EXUP cable adjustment.

• Cooling system: Radiator-cap pressure testing, thermostat checks, oil-cooler service, and water-pump assembly removal and inspection.

• Brakes and chassis: Caliper and master-cylinder service, hydraulic brake bleeding, front-fork rebuilds, steering-head checks, wheel service, and swingarm inspection.

• Electrical diagnosis: ECU diagnostic mode, FI and immobilizer fault tables, ignition and starting checks, charging-system troubleshooting, and wiring diagrams.

Written primarily for Yamaha dealers and qualified mechanics, this manual assumes a basic understanding of motorcycle mechanics and the use of the specified test equipment and special tools.

Engine and Transmission Repair

Step-by-step instructions for the liquid-cooled DOHC inline-four extend to crankcase separation, bearing-clearance checks, and crankshaft and piston installation. Clutch assembly-width adjustment distinguishes the available plate thicknesses; transmission checks include gear engagement and shaft runout.

The valve-seat section specifies titanium intake and exhaust valves and prohibits reuse after lapping. A separate camshaft warning explains that uneven cap-bolt tightening can damage the cylinder head, caps, and camshafts.

The Engine Oil Lubrication Chart traces oil supply to the internal assemblies.

YCC-T and Fuel-System Diagnosis

Yamaha Chip Controlled Throttle system and control outlines explain ECU CPU functions, motor-driven throttle valves, and the separate throttle-valve and cable-pulley position sensors.

Fuel-pressure testing identifies the YU-03153 gauge and YM-03176 adapter; separate procedures cover fuel-pump removal and installation.

Injector coverage includes removal, inspection, and diagnostic-mode actuation tests; the throttle bodies themselves are not to be disassembled.

EXUP troubleshooting distinguishes electrical circuit faults from a stuck servo motor and includes an actuator test.

Cooling, Brakes, and Suspension

Cooling System Diagrams show hose and pipe routing between the radiator, thermostat, water pump, and oil cooler. Front-fork instructions specify oil-level measurement conditions, damper bleeding, and seal orientation.

Brake chapters give piston and cylinder inspection criteria and identify seals requiring replacement during disassembly. Always double-check torque values and component routing before releasing a motorcycle for a test ride.

Electrical Fault Tracing

The fault-code tables connect meter indications to likely causes, circuit checks, and reinstatement methods. Used with sensor resistance and output-voltage tests, they help you investigate wiring, sensor, and power-supply faults before selecting replacement components.

Immobilizer coverage includes key-code registration and component-replacement requirements. Battery-capacity and AC-magneto output tables accompany charging-system tests.

Cable Routing views complement the ignition, electric-starting, and fuel-injection circuit diagrams, allowing connector checks to be matched to the relevant system.

Examples of Valve and Cooling Specifications

Valve-clearance tables specify 0.12–0.19 mm for the intake valves and 0.16–0.23 mm for the exhaust valves, measured cold. These values accompany the clearance-check and valve-pad selection procedures.

Cooling specifications list a radiator capacity, including all routes, of 2.30 L and a thermostat opening temperature of 71 °C. The cooling chapter provides the corresponding cap-pressure and thermostat checks.
