Suzuki GSX1300R Hayabusa 2008 Service Manual (P/N 99500-39350-03E)

Suzuki Motor Corporation’s September 2007 factory service manual, P/N 99500-39350-03E, covers the 2008 Hayabusa GSX1300R K8 in E-02, E-19, E-03, E-24, E-28, and E-33 specifications, plus GSX1300RUF K8 (E-19).

Text Search, Bookmarks and PDF Contents

Navigation and diagram detail: Service text is searchable, with embedded bookmarks for chapters and individual procedures. The covers and opening emissions notice do not support text search. Small labels in the dense wiring diagrams require zooming.

The ZIP contains one printable, 658-page PDF in English. This total includes two covers, an emissions notice, foreword, contents page, publication page, and six blank or header-only pages.

Engine Overhaul, FI Troubleshooting and Chassis Service

The following selected service topics outline the manual’s scope. Other material includes compression testing and exhaust-system servicing.

• Engine repair: Step-by-step procedures for engine removal and installation, top- and bottom-end disassembly and assembly, camshaft timing, valve-guide replacement, and valve-seat repair.

• Transmission and clutch: Countershaft and driveshaft gear disassembly, shift-fork inspection, wet multi-plate clutch service, and hydraulic clutch master-cylinder and release-cylinder repair.

• FI diagnosis: Electrical circuit inspections, user/dealer-mode diagnosis, Suzuki Diagnosis System testing, and separate checks for primary- and secondary-injector circuits.

• Fuel, lubrication and cooling: Fuel-pressure, pump-delivery, and oil-pressure tests, cooling-system pressure testing, and water-pump disassembly, inspection, and rebuilding.

• Suspension and steering: Front fork overhaul, swingarm and cushion-lever bearing replacement, steering-stem bearing service, and steering tension adjustment.

• Brake service: Front and rear caliper and master-cylinder disassembly, component inspection, reassembly, fluid replacement, and hydraulic bleeding, supported by symptom-diagnosis tables.

Suzuki wrote this manual for people with the knowledge, skills, and equipment—including special tools—needed to service Suzuki motorcycles.

Market Variants and Component Identification

The country-code table distinguishes E-19 GSX1300R coverage beginning at JS1CK111100100001 from GSX1300RUF coverage beginning at JS1CK211100100001.

E-33 material includes evaporative-emission system service and purge-solenoid testing. Immobilizer operation and antenna service apply to E-02, E-19, and E-24. Throttle-body identification distinguishes 15H1 for E-33 from 15H0 for other markets.

Periodic Maintenance and Internal Engine Work

The maintenance schedule uses miles, kilometers, and months for air cleaner replacement, valve-clearance checks, fuel-line inspections, and cooling-system maintenance. Lubrication points and drive-chain inspection, adjustment, cleaning, and replacement are documented; chain replacement references cutting and joining tool 09922-22711.

Internal engine work extends to piston and ring inspection, crankshaft and connecting-rod bearing selection, thrust-clearance adjustment, and crank-balancer assembly. A separate chart identifies components removable with the engine still in the frame.

The valve-seat repair section explains why lapping the titanium valves after seat servicing can remove their wear-resistant surface treatment.

SDS Diagnosis and Throttle-Control Adjustments

Fault tracing: Suzuki Diagnosis System (SDS) procedures cover current and stored diagnostic trouble codes, fault-condition data, and history-code clearing. Comparing current readings with saved data supports diagnosis of running problems, including abnormal idling without a DTC.

The code tables identify C00 as no detected fault and associate C-codes with their P-codes. C62/P0443 concerns the E-33 EVAP purge circuit. Dedicated diagnostic charts also address secondary throttle valve actuator (STVA) and PAIR control solenoid faults.

Throttle control: Procedures include SDS-assisted throttle synchronization, idle speed control (ISC) learned-value reset and opening initialization, throttle position (TP) reset, and TP/secondary throttle position (STP) sensor adjustment.

Electrical checks extend to the drive mode selector, ignition coils, starter interlock, generator, and regulator/rectifier. Diagnostic equipment references include SDS set 09904-41010 and mode select switch 09930-82720.

Wiring and Mechanical Diagrams

Separate wiring diagrams cover E-02/E-19/E-24, E-03/E-28, and E-33. Harness-routing and component-location drawings supplement the circuit diagrams.

The FI System Wiring Diagram and Terminal Alignment of ECM Coupler connect circuit-testing information with the relevant components and ECM terminals. Mechanical references include the Camshaft and Sprocket Assembly Diagram, Engine Lubrication Circuit Diagram, and Cooling Circuit Diagram. The EVAP Canister Hose Routing Diagram applies specifically to E-33.

Chassis Procedures and Rear Shock Limits

Wheel-bearing replacement, wheel balancing, combination-meter testing, lighting service, and exterior-panel removal are covered.

Rear shock service excludes internal rebuilding. Suzuki treats the shock as a nonserviceable assembly; the manual instead documents inspection, adjustment, replacement, and disposal.

Always verify your measurements against the published OEM parameters before operating the motorcycle, and complete the brake and steering checks specified for the repair.

Selected Valve-Clearance and ECT Test Specifications

Service tables provide engine and chassis tightening torques, fluid capacities, wear limits, and ECM sensor reference values.

For the covered GSX1300R models, cold valve clearance is 0.08–0.18 mm at the intake valves and 0.18–0.28 mm at the exhaust valves. Separate intake and exhaust shim-selection charts support the adjustment procedure.

The engine coolant temperature (ECT) sensor inspection specifies approximately 2.45 kΩ at 20 °C (68 °F). Its temperature/resistance table provides further reference points for assessing sensor response as temperature changes.
