2007–2009 Yamaha FZ6 FZ6-N FZ6-S FZ6-NA FZ6-SA FZS6W FZS6WC Service Manual (P/N LIT-11616-20-60)

• Two Yamaha factory service manuals totaling 932 pages: a 394-page U.S./California PDF and a 538-page 2007 FZ6 variant PDF.
• Engine repair covers removal, crankcase separation, cylinder-head disassembly, and camshaft/timing-chain installation, with inspection and reassembly procedures.
• Wet multi-disc clutch and six-speed transmission repair includes clutch-pack inspection, shaft and gear checks, and shift-drum/shift-fork service.
• Fuel-injection diagnostics include meter-operated diagnostic mode, fault-code troubleshooting, sensor readings, and actuator tests for injectors, ignition coils, and relays.
• Front and rear brake caliper/master-cylinder service is joined by ABS-specific bleeding, hydraulic-unit operation tests, and wheel-sensor diagnosis for equipped variants.
• Chassis procedures cover fork disassembly and seal replacement, steering-head bearings, swingarm inspection, wheel bearings, and static wheel balancing.
• Cooling-system work includes radiator-cap pressure testing, thermostat inspection, oil-cooler service, and water-pump disassembly and seal installation.

Documentation Coverage

The U.S. publication, P/N LIT-11616-20-60, covers FZS6W/FZS6WC and was first issued in October 2006. Its additional cover identifier is 4S8-28197-10. Model codes distinguish 4S82 for the U.S. version and 4S83 for California, with California-specific evaporative-emission canister and rollover-valve hose routing.

The companion manual, 4S8-28197-E0, is the 2007 FZ6 publication, first edition August 2006. European coverage includes FZ6-N/FZ6-S Standard models, FZ6-NA/FZ6-SA ABS models, FZ6-NHG/FZ6-SHG High-grade models, and FZ6-NAHG/FZ6-SAHG High-grade+ABS models. Australian FZ6-NHGW/FZ6-SHGW versions are also identified.

These distinctions matter when selecting front-brake procedures, throttle-body and ECU specifications, instrument-panel instructions, and wiring diagrams. The international manual separates Standard and High-grade equipment rather than treating every FZ6 as the same configuration.

Periodic Maintenance and Internal Engine Work

For the liquid-cooled DOHC four-cylinder engine, routine service includes valve-clearance inspection and shim selection, throttle body synchronization, compression testing, and engine oil-pressure measurement. Maintenance charts address emission controls, chassis checks, and lubrication points. The international edition also provides separate Standard and High-grade exhaust-gas CO adjustment procedures.

Internal engine coverage extends to valve-guide replacement and valve-seat lapping, piston and ring inspection, and color-coded connecting-rod and crankshaft bearing selection using Plastigauge clearance checks. Oil-pump, relief-valve, generator, and starter-clutch work are covered as separate assemblies.

Yamaha's camshaft-cap cautions address the risk of damaging the cylinder head, camshafts, and caps through uneven bolt loading.

Electrical Diagnosis, Immobilizer, and ABS

The international edition's immobilizer chapter covers fault-code diagnosis, replacement-part requirements, and key-code registration, including the role of the red code re-registering key. The Starting Circuit Cut-off System Operation diagram supports diagnosis of neutral, clutch, and sidestand interlock faults.

ABS troubleshooting distinguishes stored faults from present malfunctions and includes post-service checks. Its ABS Connector Location Chart identifies connector positions and terminals for circuit testing. A specific electrical caution explains that reversed tester connections can destroy the ABS motor relay's diode.

Technical Reference and Specifications

Component-specific torque tables, chassis geometry, fluid capacities, wear limits, clearance specifications, and electrical test values accompany the repair sections. The Engine Oil Lubrication Chart traces the oil circuit, while Cooling System Diagrams and model-specific Cable Routing drawings document hose and harness arrangements. Exploded assembly views identify component order and associated fasteners.

The special-tool tables identify the YU-44456 synchronizer for throttle-body balancing, YM-91042 universal clutch holder, and 90890-03149 ABS test coupler adapter. These references show which jobs call for equipment beyond ordinary hand tools.

Rear shock coverage is limited to removal, inspection, preload adjustment, replacement, and disposal—not internal rebuilding or gas recharging. The ABS hydraulic unit is likewise treated as a test-and-replace assembly, not a unit for internal disassembly.

Accurate factory torque values and structural clearances are critical to safe operation. Brake, fuel-system, and suspension repair is intended for qualified mechanics and experienced owners equipped for this work.
