2001–2002 Suzuki GSX-R600 Service Manual (P/N 99500-35080-01E)

• 2001–2002 Suzuki GSX-R600 service reference: a 399-page PDF containing Suzuki’s K1 factory publication, P/N 99500-35080-01E.
• Details complete engine disassembly and reassembly, cylinder-head service, crankshaft inspection, and six-speed transmission and wet-clutch repair.
• Covers Dealer Mode fuel-injection diagnosis, secondary-throttle system testing, fuel-pump checks, and throttle-valve synchronization.
• Cooling-system work includes radiator pressure testing, thermostat and fan checks, and water-pump disassembly and seal replacement.
• Chassis procedures cover front-fork overhaul, swingarm and suspension-linkage service, brake-caliper and master-cylinder rebuilding, and brake bleeding.
• Electrical troubleshooting addresses charging, starting, and ignition faults, supported by system circuits and market-specific wiring diagrams.

The workshop text is Suzuki’s September 2000 K1 edition. It is written for people with Suzuki motorcycle service knowledge, repair skills, and the required workshop equipment and special tools.

Market coverage identifies E-02 (U.K.), E-03 (U.S., except California), E-19 (EU), E-24 (Australia), E-28 (Canada), and E-33 (California). GSX-R600UD and GSX-R600UF are specifically listed as E-19 EU variants.

Technical Coverage and Engine Systems

Compression and oil-pressure testing help diagnose the 599 cc, fuel-injected four-cylinder before teardown. An engine-in-frame serviceability table separates jobs that can be done with the engine installed from those requiring removal.

Cylinder-head repair includes valve-guide replacement, valve-seat cutting, valve-clearance shim selection, and camshaft timing. Lower-end work covers crankshaft and connecting-rod bearing selection by identification and color codes, plus crankshaft thrust-clearance adjustment.

The Transmission Parts Location view shows the arrangement of gears, bushings, washers, and retaining rings. The camshaft section also explains how uneven journal-holder seating can damage the cylinder head or holder thrust surfaces.

Fuel Injection and Secondary Throttle Diagnostics

User Mode and Dealer Mode are explained separately, with fault-code tables and ECM fail-safe behavior. The secondary-throttle section distinguishes the STC unit, STV actuator, and STP sensor and provides dedicated circuit tests. Related procedures cover injector and fuel-filter service, throttle-position adjustment, and cable-operated fast-idle adjustment. PAIR reed-valve and control-valve testing extends the intake-air coverage.

The FI System Diagram and FI System Wiring Diagram connect component operation with circuit diagnosis. Tool references include the 09930-82710 mode select switch and 09913-13121 vacuum balancer gauge, with gauge calibration covered before synchronization work.

A throttle-body caution identifies snapping the throttle valve shut with its cables disconnected as a possible cause of throttle-valve and throttle-body damage.

Cooling, Lubrication, and Chassis Repair

The Cooling Circuit and Engine Lubrication System Chart trace coolant and oil flow. Inspection coverage extends to piston-cooling oil jets, the oil-pressure regulator, and the oil strainer.

Chassis work goes beyond suspension settings: steering-stem bearing replacement and tension adjustment, wheel-bearing service, and swingarm pivot adjustment are included. Front and rear suspension data cover spring preload and rebound/compression damping. Rear-shock coverage is removal, inspection, replacement, and adjustment—not an internal shock rebuild.

Precision Data and Workshop Reference

Reference tables cover valve and bearing clearances, piston and cylinder limits, fluid capacities, component torque, fuel-pressure tests, and electrical test values. The chassis torque table distinguishes rear-axle specifications for E-03/E-28/E-33 from those for other markets.

Wiring diagrams are grouped for E-03/E-28/E-33, E-02/E-19, and E-24. The Starter System and Side-Stand/Ignition Interlock System circuit and troubleshooting chart support no-crank diagnosis. Battery and combination-meter checks, fuse identification, and wiring-harness, cable, and hose-routing drawings support electrical repair.

Always review the manual’s safety precautions, ensure adequate workspace ventilation during fuel-system work, and use a calibrated torque wrench for specified fasteners.
