2004 Yamaha YZF-R6 SS Kit Manual (P/N LIT-11616-16-45)

This 625-page PDF set combines Yamaha factory repair information for the 2003-2005 YZF-R6 with the YEC race-kit data used to configure the '04 YZF-R6 SS race specification. Page breakdown: 434-page base service manual; 40-page 2004 supplement; 64-page 2005 supplement; 73-page YEC kit booklet; and 5-, 4-, and 5-page paint bulletins for 2003, 2004, and 2005.

• Covers YZF-R6R/YZF-R6RC (5SL3/5SL4), YZF-R6SR/YZF-R6SRC (5SL7/5SL8), YZF-R6S/YZF-R6SC (5SLD/5SLE), and YZF-R6T/YZF-R6TC (5SLR/5SLS).
• Details engine removal and internal repair, including camshafts, cylinder head, valves, starter clutch, generator, clutch, oil pump, crankcase, connecting rods, pistons, crankshaft, shift mechanism, and transmission.
• Includes chassis repair for wheel and brake-disc inspection, static balancing, master-cylinder and caliper service, hydraulic brake bleeding, front-fork work, steering-head service, rear shock removal, swingarm installation, and drive-chain checks.
• Provides fuel-injection and electrical diagnosis through ECU self-diagnostics, fail-safe tables, diagnostic mode, injector and throttle-position-sensor checks, fuel-pump testing, circuit-specific troubleshooting, and model wiring diagrams.
• Breaks the YEC package into 32 numbered kit-part sections, covering race camshafts and adjustable sprockets, head-gasket selection, sub-radiator and oil-pump kits, bell-mouth combinations, titanium exhaust, kit transmission and option gears, ECU and harness, controls, brakes, chassis protection, suspension components, and the valve-seat cutter set.
• Adds race setup references for SS/ST ECU control data, fuel-injection adjustment ranges, ignition offset, sensor diagnosis, gearing selection, front-fork and rear-shock baseline adjustment, symptom-based setup charts, and the speed-versus-ratio table.

Factory Service and Repair Coverage

The YZF-R6R/YZF-R6SR/YZF-R6RC/YZF-R6SRC Service Manual, P/N LIT-11616-16-45 (5SL-28197-10), is the main repair reference. Exploded views and job charts support removal, disassembly, inspection, assembly, installation, and final adjustment. Specification chapters provide component-specific torque tables, lubrication data, fluid capacities, wear limits, clearances, cable routing, and electrical test values.

The 2004 Supplementary Service Manual, P/N LIT-11616-17-46 (5SL-28197-11), updates the S/SC models with revised specifications, fuel-pump installation information, air-induction diagrams, ignition and lighting diagnosis, cable routing, and a dedicated wiring diagram. The 2005 Supplementary Service Manual, P/N LIT-11616-18-45 (5SL-28197-12), adds T/TC changes for brake bleeding, front brake master-cylinder and caliper service, front-fork disassembly and assembly, radiator service, starting-system diagnosis, and cooling-system troubleshooting. It also identifies tools such as the YM-01441 fork spring compressor and YM-01442 fork seal driver. The 2004 book is used with the base manual; the 2005 book calls for both earlier publications, so neither supplement is a stand-alone repair manual.

Engine and Performance Kit Configuration

The YEC '04 YZF-R6 SS Kit Manual gives competition-specific information outside routine street-bike service coverage. Its engine sections address SS baseline specifications, squish-height and head-gasket selection, cam timing, valve-seat work, connecting-rod installation, cylinder-head installation, intake-funnel combinations, reduced-loss oil-pump use, and the all-titanium exhaust layout. ECU coverage documents the two control-data modes plus the available fuel and ignition correction functions; it does not contain a full fuel-map table.

Two compatibility traps are stated clearly. The kit transmission gears cannot be mixed with standard gears, and incorrect cam-sprocket indexing can damage the engine instead of merely reducing power. The sub-radiator is designed around the kit exhaust arrangement and specified hose and cable clearances; it is not presented as a universal bolt-on cooling upgrade.

Chassis and Suspension Setup

YEC chassis content includes rear-shock and front-fork spring options, the complete front-fork damper set, steering-damper mounting, racing brake discs and pads, adjustable footrests, protection kits, and basic fork and shock setup guidance. The suspension chapters explain preload, rebound, and compression adjustment and provide terrain/symptom charts for harshness, lack of traction, bottoming, kick-out, and headshake.

Useful visual references include exploded removal and assembly views, cooling-system diagrams, the engine-oil lubrication chart, fuel-injection wiring and diagnostic charts, full model wiring diagrams, and the YEC speed-versus-ratio table. Three Yamaha technical bulletins (M2003-001, M2004-003, and M2005-004) add R6 model codes and body, frame, and wheel paint references. These are all-model Yamaha charts that include the R6, not R6-only paint manuals. The 2004 chart also lists the YZF-R6SS/C (5SLH/5SLJ) paint entry.

The YEC booklet is marked for racing use only, not public-road use, and directs the mechanic to the service manual for normal assembly and maintenance procedures. Competition engine, brake, and suspension work requires measurement and final operational checks against the listed factory specifications before track use. Its cover identifies an '04 SS Kit Manual, while the inside title, final wiring diagram, and speed-versus-ratio table identify the 2003 YZF-R6. In the YEC material, SS denotes the Super Sports race specification; it should not be confused with the YZF-R6SS/C paint-chart model designation.
