Suzuki DL650 V-Strom 2004–2009 Service & Repair Manual (P/N 99500-36130-03E)

This Suzuki service manual covers scheduled maintenance through complete engine repair for the DL650K4 ('04 model), publication 99500-36130-03E. Its market table also lists the EU-market DL650-UE. This is the 2004 K4 edition; later model-year supplements and ABS-specific repair sections are not included.

PDF Text Search and Wiring Detail

Search and diagram readability: The PDF is partially searchable through an existing OCR text layer and has no embedded bookmarks. The fuel-system contents page and appended wiring sheets have no searchable text. Small wiring labels require zooming.

The RAR download contains one printable English PDF with 467 pages: 465 manual pages, including the cover and introductory material, plus two appended full-sheet electrical redraws. Both additional sheets are already included in the total.

Engine Overhaul, Fuel Injection, and Chassis Service

These selected contents outline the main workshop coverage. Other topics include windshield adjustment and exterior-panel removal.

• Engine repair: Removal and installation, top- and bottom-end disassembly, cylinder-head and valve-gear inspection, internal servicing, and reassembly.

• Fuel-injection diagnosis: ECM self-diagnosis, user and dealer modes, fail-safe functions, malfunction-code charts, circuit inspection, and sensor and actuator testing.

• Fuel and throttle-body service: Fuel-pressure and pump-output testing, pump and filter removal, injector service, STV and throttle-valve synchronization, and TPS, STP, and fast-idle adjustment.

• Cooling and lubrication: Circuit inspection, radiator and cap checks, fan and thermo-switch testing, thermostat and ECT-sensor service, water-pump overhaul, and oil-pressure checks.

• Chassis repair: Wheel service, fork rebuilding, steering-head and swingarm work, brake-caliper and master-cylinder rebuilding, brake-fluid replacement and bleeding, and drive-chain cutting and riveting.

• Electrical troubleshooting: Charging, starting, ignition, side-stand/interlock, combination-meter, lighting, relay, switch, and battery diagnosis, with component locations, connector-handling guidance, and circuit test specifications.

Suzuki wrote this manual for people who already have the service knowledge, skills, equipment, and special tools required; it suits professional technicians and experienced DIY mechanics with workshop-level capability.

Internal Engine and Drivetrain Repair

Step-by-step procedures address camshafts, pistons, connecting rods, the crankshaft, crankcase bearings, clutch, primary drive, six-speed transmission, starter clutch, generator, and oil pump. Valve-seat servicing, shim-selection charts, cam-timing illustrations, and bearing-selection data support internal inspection and assembly.

Incorrect loosening can damage the primary-drive gear bolt, which uses a left-hand thread. Uneven seating of camshaft journal holders can damage the cylinder-head and holder thrust surfaces.

FI Fault Isolation and Throttle-Body Limits

Dedicated circuit checks cover CKP, IAP, TP, STP, ECT, IAT, tip-over, oxygen-sensor, injector, ignition, fuel-pump-relay, and PAIR faults, plus the GP switch and STV actuator. The diagnostic charts distinguish wiring and connection faults from component faults, helping narrow the cause before replacement parts are selected.

Restricted disassembly: Throttle-body work is limited to the operations shown; the STVA, throttle valves, secondary throttle valves, and link plates are not removable service items under these procedures.

Market differences: Codes identify the UK (E-02), USA except California (E-03), EU (E-19), Australia (E-24), Canada (E-28), and California (E-33). Heated oxygen-sensor inspection applies to E-02/E-19; EVAP-canister and fuel-shutoff-valve checks apply to E-33.

Cooling-System and Lubrication Service

The water-pump section distinguishes oil-seal/O-ring leakage from mechanical-seal leakage and documents bearing and seal replacement. Lubrication coverage extends to the pressure regulator, strainer, jets, pump, and oil cooler.

Suspension, Brakes, and Wheels

Wheel-bearing replacement and tire removal/installation accompany the chassis procedures. Suspension information includes preload and damping settings. Rear-shock removal, inspection, replacement, and disposal are covered, but the shock unit itself is designated unserviceable and must not be disassembled.

Workshop Diagrams, Tools, and Service Data

Exploded views carry torque, lubrication, sealant, and thread-lock callouts. Diagram examples include the FI-system wiring diagram, transmission cross-sectional view, engine-lubrication flow chart and circuit, wire-harness routing, and cooling, brake, throttle-body, PAIR, and EVAP hose-routing views. The appended electrical redraws distinguish UK/EU models from the other covered markets.

Suzuki tool references include the 09900-25008 multi-circuit tester set, 09930-82720 mode-select switch, 09913-13121 vacuum balancer gauge, and 09940-40211 fuel-pressure gauge adapter. Servicing data collects torque tables, capacities, approved fluids, clearance and wear limits, compression and oil-pressure checks, suspension settings, and electrical test values.

Before service, review the General Information precautions for pressurized fuel, brake work, hot coolant, and electrical testing around the ECM and ignition system.

Valve-Clearance and Injector-Test Examples

Valve inspection: The K4 engine's cold valve-clearance ranges are 0.10–0.20 mm at the intake valves and 0.20–0.30 mm at the exhaust valves. The maintenance section pairs these figures with shim-selection tables.

Injector diagnosis: The fuel-injector circuit check specifies 11–13 Ω at 20°C (68°F). The C32/C33 charts distinguish resistance and ground-insulation checks from supply-voltage testing.
