Suzuki SV650/SV650S 2003 Service Manual (P/N 99500-36120-03E)

Suzuki's 2003 SV650/S Service Manual, P/N 99500-36120-03E, covers the SV650 and SV650S, with factory inspection, service, and major-component overhaul procedures.

OCR Search, Bookmarks, and Diagram Detail

Search and diagram labels: OCR text search is available across the service chapters, although small diagram labels are not consistently recognized. Embedded section and page bookmarks are included. Small wiring labels require zooming.

Supplied as one printable, 495-page PDF. The total includes the original front and rear covers and the publication-details page.

V-Twin Overhaul, FI Testing, and Chassis Service

The selected coverage below gives an overview; other topics include combination-meter testing and tubeless-tire service.

• Engine and drivetrain: Engine removal, internal disassembly, cylinder-head repair, clutch inspection, transmission service, and camshaft installation procedures.

• Periodic maintenance: Step-by-step tappet-clearance adjustment, drive-chain inspection and adjustment, compression testing, and engine oil-pressure checks.

• FI diagnosis: User and dealer modes, malfunction code charts, ECM connector views, sensor testing, and circuit fault isolation.

• Fuel and throttle body: Fuel-pressure and pump-delivery testing, injector service, throttle synchronization, STV synchronization, and TPS/STPS adjustment.

• Cooling and lubrication: Cooling-circuit testing, radiator and thermostat checks, water-pump service, oil-cooler inspection, and lubrication diagrams.

• Chassis and brakes: Front-fork overhaul, steering-stem and swingarm service, wheel-bearing replacement, brake-caliper and master-cylinder repair, and brake bleeding.

• Electrical systems: Charging and ignition troubleshooting, starter-motor overhaul, side-stand/ignition interlock tests, and model- and market-specific wiring diagrams.

Written for mechanics with the knowledge, skills, and special tools needed to service Suzuki motorcycles; generally known workshop basics are not explained.

Engine, Clutch, and Transmission Repairs

Cylinder-head, camshaft, piston, and crankshaft coverage extends to valve-guide and seat service, bearing selection, and crankcase separation. The manual also identifies components removable with the engine still in the frame.

Separate intake and exhaust tappet shim selection tables accompany the valve-train procedures. Torque tables include staged cylinder-head bolt tightening specifications. Uneven camshaft-journal holder installation can damage the cylinder-head and holder thrust surfaces.

Clutch checks cover plate wear and distortion, spring condition, and release-bearing inspection. Transmission instructions include gear and bushing inspection and shift-fork clearance measurements.

C28 Diagnosis and Throttle-Body Service Limits

Dealer-mode diagnosis uses mode-select switch 09930-82720. The code charts link detected faults to connector views and circuit checks, helping distinguish wiring and connection problems from component faults.

C28 is covered as a Secondary Throttle Valve Actuator (STVA) circuit malfunction. The fuel-system chapter distinguishes primary throttle balancing from secondary throttle valve synchronization and also covers automatic fast-idle inspection and adjustment.

Throttle-body disassembly is limited to the operations shown; the chapter prohibits removal of the STVA, throttle valves, and link plates. It also warns that using tools to turn the STVA shaft can damage the actuator.

Cooling Circuit and Lubrication References

Water-pump procedures include mechanical-seal and bearing inspection and replacement. The Engine Lubrication Flow Chart and Cooling System Hose Routing drawings support checks of oil passages and coolant connections.

Model-Specific Chassis and Brake Work

SV650 and SV650S instructions distinguish handlebar arrangements, front master-cylinder assemblies, brake-hose routing, and fork-oil settings. Swingarm coverage includes pivot and suspension-linkage bearings. Brake procedures cover the twin-disc front and single-disc rear systems.

Rear-shock coverage includes removal, inspection, replacement, and preload adjustment; the shock unit itself is specified as nonserviceable.

Always ensure your workspace is properly ventilated and secure the motorcycle on reliable stabilization stands before initiating any heavy service work.

Electrical Fault Charts and Emission Controls

Charging tests distinguish battery leakage, generator output, and regulator/rectifier checks. Starter and ignition fault charts address no-crank and no-spark complaints.

Emission Control Information covers PAIR reed-valve and solenoid checks. California E-33 coverage includes the EVAP canister, tank-pressure control valve, and EVAP Canister Hose Routing diagram.

Tappet, STVA, and Fluid-Capacity Examples

Cold tappet clearance is specified at 0.10–0.20 mm intake and 0.20–0.30 mm exhaust. Separate shim-selection tables support the adjustment procedures.

The C28 diagnostic section specifies an STVA resistance of approximately 7–14 ohms.

Capacity tables list 1.7 L of coolant and 3.1 L of engine oil after overhaul, with separate oil quantities for oil-only and filter-change service.
