2005–2008 Suzuki GSF650 & GSF650S Bandit Factory Service Manual (P/N 99500-36150-01E)

This Suzuki Motor Corporation factory service manual (P/N 99500-36150-01E) covers the naked GSF650 and faired GSF650S Bandit. Originally issued for the 2005 model year, it documents the air-cooled, carbureted DOHC configuration, with UK, European-market, and Canadian-market information.

• Engine and transmission: Engine removal, internal inspection and overhaul, clutch repair, starter-clutch checks, and transmission disassembly and reassembly.

• Maintenance and testing: Valve-clearance adjustment, compression-pressure testing, oil-pressure checks, scheduled maintenance, and lubrication-point references.

• Fuel and PAIR systems: KEIHIN CVR32 carburetor overhaul and synchronization, throttle-position sensor adjustment, and PAIR air-supply valve testing.

• Suspension and steering: Front fork overhaul, steering tension adjustment, swingarm and linkage bearing service, and seat and handlebar height adjustments.

• Brakes and final drive: Caliper and master-cylinder overhaul, brake bleeding, wheel-bearing replacement, and drive-chain cutting and joining.

• Electrical diagnosis: Digital-ignitor troubleshooting, generator and IC regulator tests, starter-system diagnosis, combination-meter checks, and model-specific wiring diagrams.

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

Engine Overhaul and Drivetrain Service

Internal engine coverage extends to valve guides and seats, camshaft journals, piston and cylinder wear, and crankshaft thrust clearance. Bearing selection tables match connecting-rod and crankshaft/crankcase codes to bearing colors and part numbers, helping you identify the correct replacement shells.

The transmission section provides shaft assembly views, shift-fork inspection, and primary reduction and gear-ratio tables with tooth counts. Engine reassembly cautions explain how uneven camshaft-holder tightening can damage the cylinder head or holder thrust surfaces.

Lubrication service covers the oil cooler, sump filter, oil jets, and pressure regulator. Oil-pump removal requires engine removal and crankcase separation; the pump is replaced as a complete assembly rather than rebuilt internally.

Carburetor Variants and PAIR Testing

Carburetor specification tables distinguish E-02/E-19, E-19 U-type, E-28, and P-37 configurations through identification codes, jetting, and needle specifications. Heater and thermo-switch tests apply to E-02/E-19 models.

The synchronization procedure includes vacuum-balancer setup using tool 09913-13121. Separate instructions cover throttle-position sensor positioning and PAIR reed-valve inspection. A carburetor cleaning caution explains why compressed air can damage a diaphragm that is still installed.

Forks, Steering, and Brake Service

The GSF650 and GSF650S have different fork spring limits and oil settings, plus separate rear-spring preload baselines. Rear suspension procedures cover the swingarm and linkage bearings; the rear shock absorber itself is a nonserviceable replacement unit.

Cold tire-pressure data covers solo and dual riding. Drive-chain replacement includes riveting checks and identifies cutting/joining tool 09922-22711. Brake and steering work requires secure support and the manual's post-service checks before riding.

Electrical Fault Tracing and Routing Drawings

Charging, starting, and no-spark diagnostic charts connect symptoms to component tests, including gear-position switches, ignition coils, and the signal generator. Combination-meter documentation adds connector pin assignments, fuel-level tests, and speed-sensor checks.

Illustrations include separate GSF650 and GSF650S wiring diagrams, the Engine Lubrication System Chart, Cylinder Head Cooling System Chart, and model-specific cable-routing views. Wire-harness and carburetor hose routing drawings help avoid trapped wiring and interference with the throttle mechanism. Exploded views and torque charts identify fasteners, tightening values, and lubrication points.

Examples of Valve Clearances, Oil Capacity, and Fork Travel

These are a few examples of the service specifications included for these models. Cold valve clearances are 0.10–0.15 mm for the intake valves and 0.18–0.23 mm for the exhaust valves.

The engine-oil capacity table lists 4,600 ml for an overhaul fill. Chassis specifications give a front fork stroke of 130 mm, alongside the model-specific fork spring and oil-level data.

PDF Search, Bookmarks, and Wiring Detail

Search and diagram access: Text is searchable, and bookmarks cover the main chapters. The Carburetor and Wiring Diagram bookmarks incorrectly open the cover; use PDF p. 143 and PDF pp. 298–299, respectively. Small wiring labels are legible when enlarged.

The download is one printable, 333-page PDF in English. The total includes 327 technical pages, one front cover, three introductory pages, one publication page, and one back cover.
