2011 Yamaha FZ8NA(C) Service Manual (P/N LIT-11616-24-07)

This Yamaha service manual covers the 2011 FZ8NA(C), including the 39P2 (USA) and 39P3 (California) variants. It is the first edition, November 2010, P/N LIT-11616-24-07, with 39P-28197-10 also printed on the original cover.

PDF Search, Bookmarks and Wiring Sheets

Search and diagram detail: The main text is searchable, with embedded chapter and section bookmarks. The final wiring sheets have no searchable diagram labels; small connector markings and wire codes require zooming.

One printable, English-language 478-page PDF contains the 476-page manual—including its front and rear covers, preliminary material and six blank pages—plus two appended wiring-diagram sheets.

Engine Overhaul, Chassis Service and FI Diagnosis

These highlights are a selection of the manual’s contents, rather than a complete table of contents. Other documented topics include starter-clutch inspection and drive-chain riveting.

• Engine repair: Step-by-step procedures for engine removal, camshaft timing, cylinder-head service, and crankshaft, connecting-rod and piston inspection.

• Clutch and transmission: Clutch disassembly and plate inspection, shift-fork and shift-drum checks, and transmission shaft disassembly and installation.

• Brakes and suspension: Brake-caliper and master-cylinder repair, hydraulic bleeding, telescopic-fork overhaul, and steering-head bearing service.

• Fuel injection: Fuel-pressure and injector checks, throttle-body cleaning and synchronization, and throttle and sub-throttle position-sensor adjustment.

• Cooling and lubrication: Radiator-cap testing, thermostat checks, water-pump seal replacement, oil-pump inspection, and engine oil-pressure testing.

• Electrical diagnosis: Ignition, starting and charging troubleshooting, ECU self-diagnosis, fault-code tables, and system-specific circuit diagrams.

Written primarily for Yamaha dealers and their qualified mechanics, this manual assumes a basic understanding of mechanics and vehicle repair techniques.

Engine Repair and Maintenance

Engine service goes beyond routine adjustments. The internal repair sections cover piston-to-cylinder clearance, piston-ring inspection, crankcase assembly, and crankshaft and connecting-rod bearing selection.

The inspection limits, exploded assemblies and job charts let you assess components during teardown and identify parts marked for replacement. Shim-under-bucket valve-clearance adjustment includes valve-pad selection, while the bearing sections explain Plastigauge checks and selection using stamped identification marks.

The connecting-rod section specifies new bolts and plastic-region angle tightening, and warns that interchanging rod bearings can cause engine damage.

Prior to servicing high-stress powertrain components, always verify manufacturer limits and observe standard shop safety practices to prevent equipment damage or personal injury.

Tightening and Lubrication Specifications

Expect extensive torque tables for the engine, chassis and fasteners, with values in Nm, m·kgf and ft·lbf. Engine-oil and coolant capacities accompany the relevant service specifications.

The Engine Oil Lubrication Chart and lubrication diagrams trace internal oil paths. Component illustrations identify applications for molybdenum disulfide grease, lithium-soap-based grease and Yamaha bond No.1215.

Fork, Steering and Brake Service

Fork overhaul includes damper-rod disassembly, seal installation and oil-level measurement, with different left- and right-side damper details. Steering-head instructions cover bearing and race replacement, followed by adjustment checks.

Brake sections distinguish caliper and master-cylinder inspection from pad replacement and bleeding. Rear-shock coverage includes removal, inspection and linkage service; the nitrogen-charged shock unit is not to be opened.

Throttle Bodies, Emissions and Cooling

California-specific material covers canister hoses and rollover-valve testing. Air-induction service includes reed-valve inspection and solenoid checks.

The throttle-body instructions distinguish synchronization from throttle-valve adjustment and warn that disturbing factory screws can alter idle speed or cause related malfunctions. Tool references identify the Vacuummate YU-44456 and fuel-pressure adapter YM-03176.

Cooling System Diagrams show radiator, thermostat and oil-cooler connections. Water-pump instructions extend to impeller inspection and mechanical-seal installation.

Electrical Fault Isolation and Harness Reference

Fault-code troubleshooting links displayed codes to probable causes, wiring checks, sensor tests and reinstatement methods. This provides a documented way to narrow down a fault before deciding whether a sensor needs replacement.

Ignition System and Fuel Injection System circuit diagrams support those checks. Cable Routing illustrations and the final monochrome and color Wiring Diagram sheets provide additional harness and connector reference.

Selected Valve, Idle and Electrical Specifications

The valve-adjustment specifications give a cold intake-valve clearance of 0.10–0.17 mm. The idle-speed procedure specifies 1150–1250 r/min after warming the engine.

Electrical reference data lists crankshaft-position-sensor resistance at 336–504 Ω at 20 °C (68 °F), with a corresponding sensor-test procedure. The fuse table identifies a 50 A main fuse.
