2004–2009 Suzuki VZ800 Marauder Boulevard M50 Factory Service Manual (P/N 99500-38050-01E)

Prepared by Suzuki Motor Corporation, this 454-page PDF is P/N 99500-38050-01E, dated December 2004 and identified on the cover as the VZ800K5 Service Manual. Its stated application is the Suzuki VZ800K5 ('05-model') with an 805cc liquid-cooled 45-degree V-twin, electronic fuel injection, a five-speed constant-mesh transmission, and shaft drive. It should not be treated as blanket 2004-2009 VZ800 coverage.

Suzuki states that this manual is written for people who already have the knowledge, skills, workshop equipment, and specified special tools needed to service Suzuki motorcycles. It is not a beginner-level repair guide. Across 12 indexed sections, it moves from periodic maintenance and internal repair to emissions controls and electrical diagnosis.

• Engine and transmission repair: Covers engine removal and installation, complete disassembly and reassembly, camshaft and cam-chain service, cylinder-head and valve work, piston and crankshaft inspection, clutch repair, oil-pump service, and internal transmission inspection.
• Secondary and final drive service: Details bevel-gear removal, disassembly, bearing and seal work, selective-shim adjustment, backlash measurement, tooth-contact checks, reassembly, and final installation of the shaft-drive units.
• FI and fuel-system diagnosis: Provides dealer-mode and SDS procedures, stored-code reset, fail-safe information, sensor and actuator circuit tests, fuel-pressure and pump checks, injector service, throttle-body work, TPS/STP adjustment, fast-idle setting, and throttle synchronization.
• Chassis repair: Walks through wheel, tire, front-fork, steering, and rear-suspension service, plus front caliper and master-cylinder rebuilding, rear-brake work, brake-fluid replacement and bleeding, steering-tension adjustment, and wheel balancing.
• Electrical fault finding: Covers charging, ignition, starter, side-stand/ignition interlock, speedometer, pilot lamps, relays, switches, battery service, component locations, connector testing, and market-specific wiring diagrams.
• Workshop reference material: Supplies exploded assembly views, routing drawings, troubleshooting charts, special-tool identification, component-specific torque tables, fluid data, electrical test specifications, service limits, wear limits, and adjustment clearances.

Model and Market Coverage

Coverage is organized by factory area code and effective frame number. E-02 U.K. begins at JS1B4111200100001; E-19 E.U. VZ800 at JS1B4111100100001; E-19 E.U. VZ800U at JS1B4211100100001; and E-24 Australia at JS1B4111300100001. E-03 U.S. except California, E-28 Canada, and E-33 California begin at JS1VS56A 52100001.

Market differences are carried into the service sections. Heated-oxygen-sensor coverage applies to E-02, E-19, and E-24; the EVAP system is specific to E-33; and catalyst coverage is identified for E-02, E-19, E-24, and E-33. The final full-vehicle wiring diagrams are split between the E-02/E-19/E-24 and E-03/E-28/E-33 configurations.

Factory Diagnostics and Illustrations

Named references include the FI System Wiring Diagram, Cooling Circuit, Engine Lubrication System Chart, PAIR System Diagram, E-33 EVAP Canister Hose Routing, and the two market-grouped wiring diagrams. The FI chapter also maps ECM terminals and develops the diagnostic coverage into circuit-specific fault tests rather than stopping at a code list.

The special-tool section identifies factory equipment by number. Examples include the SDS Set 09904-41010, mode selection switch 09930-82720, vacuum balancer gauge 09913-13121, and backlash measuring tool 09924-34510. Those references matter for diagnosis, throttle synchronization, and bevel-gear setup where a generic hand-tool procedure is not enough.

Important Service Notes

The shaft-drive chapter treats the secondary driven bevel gear and its bearing as an assembly, and it requires the final drive and driven gears to be replaced as a matched pair. Trying to separate the non-serviceable gear assembly or mixing a gear pair can damage components that depend on correct backlash and tooth contact.

The FI precautions warn that front-probing a coupler can spread its female terminals, while incorrect ECM meter connections or switching couplers with the ignition on can damage the ECM or sensors. Fuel-system work involves pressurized gasoline, and brake or internal-engine repair can affect rider safety; the manual's safety controls and required equipment should be followed throughout.
