2006–2007 Suzuki GSX-R750 Factory Service Manual (P/N 99500-37130-01E)

• Set identity and scope: 590 PDF pages total — a 522-page Suzuki GSX-R750K6 service manual, P/N 99500-37130-01E, prepared in December 2005 and copyrighted 2006; a 67-page illustrated parts-diagram PDF labeled GSX-R750 K6-K7; and a one-page parts-fiche reference sheet. The OEM workshop manual itself is K6-specific, and no separate K7 service supplement is included.
• Covers engine removal and installation plus full internal service of the cylinder head and valves, cam drive, pistons, crankshaft and connecting rods, balancer shaft, clutch, gearshift system, and 6-speed transmission.
• Includes Suzuki FI self-diagnosis and SDS procedures, dealer-mode checks, DTC charts covering the manual's C11-C60 code range, fail-safe data, ECM terminal identification, sensor and actuator circuit testing, active-control checks, and fault-code reset routines.
• Details fuel-pressure and discharge testing, pump and filter service, throttle-body removal and cleaning, primary and secondary injector inspection, STP/TPS and fast-idle adjustment, and four-cylinder throttle-valve synchronization.
• Chassis repair coverage includes front-fork overhaul and setup, steering and steering-damper service, wheel and bearing work, swingarm and rear-suspension inspection, brake caliper and master-cylinder repair, tire balancing, and drive-chain cutting and joining.
• Provides periodic-maintenance charts, special-tool part numbers, component-specific torque tables, service limits and adjustment data, harness/cable/hose routing drawings, market-specific wiring diagrams, and separate illustrated parts views.

K6 Workshop Coverage and K7 Parts Scope

The workshop publication identifies the GSX-R750K6 ('06 model) and lists E-02 U.K., E-19 E.U., E-24 Australia, E-03 U.S.A. except California, E-28 Canada, and E-33 California applications. It gives effective frame-number starts of JS1CF111100100001 for E-02 and E-19 GSX-R750, JS1CF211100100001 for the E-19 GSX-R750U2, JS1CF121300100001 for E-24, and JS1GR7KA 62100001 for E-03, E-28, and E-33. The information-label table also distinguishes GSX-R750 and GSX-R750UF applications.

Coverage changes with market equipment. The FI and electrical sections identify HO2-sensor procedures for E-02 and E-19, immobilizer coverage for E-02, E-19, and E-24, and evaporative-emission material for E-33. The final wiring section is divided into full diagrams for E-02/E-19/E-24 and E-03/E-28/E-33. The K7 designation appears on the separate parts-diagram PDF, not on a K7 workshop-manual supplement.

Factory Procedures and Diagnostic Depth

The engine chapter separates components that can be repaired with the engine still in the frame from work requiring engine removal. It then follows the major assemblies through teardown, inspection, measurement, service-limit evaluation, bearing selection, and reassembly. Valve work includes cold-clearance inspection, intake and exhaust shim-selection charts, the 21-size tappet shim set P/N 12800-05830, camshaft installation, valve-timing checks, and cam-chain tensioner service.

The fuel section explains the delivery layout with no external return hose, pressure and discharge tests, fuel-pump and mesh-filter service, throttle-body disassembly/reassembly, injector checks, fast-idle setting, and throttle synchronization. FI diagnosis adds the system wiring schematic, component-location views, SDS live and stored data, and circuit-specific tests for the engine sensors, ignition coils, primary and secondary injectors, STVA, EXCVA, PAIR valve, fuel-pump and cooling-fan relays, immobilizer, and HO2 system where fitted.

The special-tool index identifies the Suzuki SDS Set 09904-41010 with CD-ROM Ver.7 99565-01010-007, mode-selection switch 09930-82720, TPS test harness 09900-28630, and fuel-pressure adapter/hose tools 09940-40211 and 09940-40220. It also catalogs the valve, bearing, clutch, rotor, steering, swingarm, front-fork, and drive-chain tooling used throughout the repair procedures.

Chassis, Electrical, and Diagram Coverage

Chassis chapters cover inverted-fork disassembly, seal and oil-level service, suspension settings, steering-bearing work, rear-shock removal, swingarm and linkage disassembly, wheel-bearing installation, front and rear brake overhaul, tire service, and final chassis adjustments. Electrical repair sections address charging, starting, the side-stand/ignition interlock, ignition and immobilizer systems, combination meter, lighting, switches, relays, and battery testing and charging.

Useful factory graphics include the FI wiring schematic, ECM terminal map, cooling circuit, engine-lubrication chart, front-fork construction view, rear-suspension construction view, and the two market-group wiring sheets. The separate 67-page parts-diagram file contains 66 numbered parts-illustration pages after its cover, spanning engine internals, fuel delivery, the rolling chassis and brakes, bodywork, instruments, and wiring harnesses.

Two manual-specific repair cautions are worth noting. The EXCVA pulley and cables must be handled in the specified adjustment position; forcing the pulley or adjusting the cables at the fully open or fully closed stop can damage the actuator's internal gearing. The rear shock absorber is identified as an unserviceable high-pressure nitrogen unit, so the manual limits normal repair to removal and replacement and separately covers pressure release before scrapping. Fuel-system and brake work also require the ventilation, ignition-control, fluid-handling, and leak-check precautions stated in the publication. This manual assumes prior motorcycle service knowledge and access to the specified tools; it is not written as a beginner's repair guide.
