2003–2009 Suzuki Burgman 650 AN650/A Scooter Service & Repair Manual (P/N 99500-36116-03E)

• Covers 2003–2009 Suzuki AN650 and AN650A Burgman 650 scooters, including base and ABS-equipped models powered by the 638cc DOHC twin-cylinder engine and electronic CVT.
• Official 653-page Suzuki PDF publication (P/N 99500-36116-03E). Represents the 2003 first edition alongside supplemental sections for model year updates through 2009.
• Contains over 50 exploded-view assembly diagrams, 30+ torque-specification tables, and comprehensive Wiring diagrams for both the FI and CVT networks.
• Covers service data for the Anti-lock Brake System (ABS), Suzuki Diagnostic System (SDS), immobilizer anti-theft system, Evaporative Emission Control System (EVAP), Pulsed Secondary Air Injection (PAIR), Idle Speed Control (ISC) valve, power wind screen, and the fail-safe function.
• Details parameters for the dealer mode, malfunction codes, Diagnostic Trouble Codes (DTC), heated oxygen sensor (HO2S), CVT secondary pulley revolution sensor, throttle position sensor (TPS), ambient air temperature sensor (AAT), engine coolant temperature sensor (ECT), and the intake air pressure sensor (IAPS).

Documented Subsystems and Overhaul Data

This Suzuki Burgman 650 technical guide lays out detailed organizational chapters for complete scooter teardown, assembly, and routine maintenance. It breaks down the primary mechanical systems into logical sections. You start with general motorcycle data and periodic maintenance schedules before moving directly into full engine mechanical overhauls. Major sub-systems detailed inside include the advanced fuel injection setup, the electronic CVT control unit, liquid cooling circuits, and the multi-plate clutch mechanisms. Standard chassis components—like front and rear disc brake systems, telescopic front forks, and swingarm geometry—are also thoroughly mapped out.

To help owners and independent mechanics bypass expensive dealership labor fees, the manual provides step-by-step instructions for procedures like a throttle valve synchronization, adjusting the automatic brake-lock system, and performing a CVT primary pulley shims adjustment. It also walks you through reading and clearing malfunction codes via the dealer mode, keeping diagnostic costs in check. Because working on these electrical or pressurized hydraulic systems carries inherent physical risks, technicians must review all factory safety protocols outlined in the initial chapters before beginning repairs or troubleshooting. To further assist with diagnostics, the manual features targeted visual references, including FI system wiring diagrams, engine lubrication system charts, tappet shim selection tables, engine coolant density-freezing point curves, tightening torque charts, and EVAP canister hose routing diagrams.

Specification Highlights

Technical depth shines through the detailed tables and diagnostic limits. The document logs crucial clearances for tappets, piston-to-cylinder tolerances, and transmission ratios directly from the manufacturer. For example, intake valve clearance is listed precisely at 0.10–0.20 mm within the cylinder head specification table. Cylinder head bolt torque values require a strict multi-stage sequence. The data specifies final-stage angles of 130°–140° during engine assembly. You will also find the Suzuki AN650 transmission oil level plug torque set exactly at 21 N·m in the gear-case maintenance data.

Having this level of precise factory data ensures components are mated correctly, preventing assembly errors and minimizing bay downtime. Accessing the exact Suzuki Diagnostic System (SDS) active control parameters and pinout voltages allows a mechanic to trace complex FI or CVT faults directly to the wiring harness. This diagnostic capability prevents the unnecessary replacement of expensive sensors or control units, keeping repair turnaround times efficient and highly profitable for any service bay.
