1992–1995 Suzuki DR650R/S & DR650RE/SE Service & Repair Manual (P/N 99500-46022-01E)

This Suzuki DR650R/S service manual covers the listed 1992–1995 variants. P/N 99500-46022-01E, second edition dated October 1994, combines the DR650RN/DR650SN base manual with update chapters for DR650RP/DR650SP, DR650RER/DR650SER, and DR650RES/DR650SES.

• Engine repair: Engine removal, crankcase separation, cylinder-head and valve service, crankshaft inspection, and camshaft and balancer-drive assembly.

• Clutch and transmission: Clutch-plate measurements, release-mechanism inspection, gearbox disassembly, shift-fork checks, and primary kick-starter service.

• Fuel and lubrication: Carburetor disassembly, needle-valve inspection, float-height adjustment, fuel-cock service, oil-pressure testing, and oil-cooler references.

• Electrical diagnosis: CDI, magneto-coil, and charging-system tests, plus de-compression control, solenoid, starter-relay, and starter-motor checks for electric-start variants.

• Brakes and front chassis: Caliper and master-cylinder service, brake bleeding, telescopic-fork overhaul, tapered-roller steering-bearing replacement, and wheel inspection.

• Rear suspension: Swingarm and linkage-bearing service, shock-absorber removal and inspection, and spring-preload settings.

Written primarily for experienced mechanics, this manual also serves apprentices and DIY mechanics using the tools and test equipment specified for the work.

Engine, Timing, and Transmission Repairs

The engine chapter provides disassembly and reassembly procedures with inspection criteria for rocker arms, valves and guides, pistons, rings, and the crankshaft. The transmission section view shows gear, washer, and circlip positions, while the valve timing diagram supports the camshaft references.

The primary drive gear nut is identified as left-hand threaded. A separate crankcase-splitting caution explains how leaving the transmission components in the wrong case half can damage the gearshift cam stopper.

Model-specific updates: The RP/SP chapter revises balancer driven sprockets and chain assembly information. The RER/SER chapter adds magneto inner-cover removal, starter-drive components, and starter torque-limiter inspection. These update chapters refer back to the earlier sections, helping you match the procedure to the complete model designation.

Carburetor, Lubrication, and Scheduled Maintenance

The Mikuni BST40SS tables distinguish carburetor identification numbers, jetting, and pilot-screw settings by market. That distinction matters when selecting the baseline settings for a regional version.

Fuel-hose and air-supply routing drawings show the relevant arrangements, including Austria and Switzerland. The Engine Lubrication/Cylinder Head Cooling System Chart traces oil through the pump, filter, cooler, and internal passages.

The periodic maintenance chart is supported by procedures for valve-clearance and de-compression adjustments, manual balancer-chain tensioning, and spark-arrester cleaning on Canadian models.

Ignition, Charging, and Electric Starting

Separate magneto-coil, ignition-coil, and charging-system checks support fault isolation for no-spark and charging complaints. The CDI and regulator/rectifier resistance tables specify Suzuki pocket tester 09900-25002; the manual notes that other meters can produce different readings.

Electric-start coverage includes de-compression control-unit and solenoid tests, starter-relay inspection, and starter-motor brush, commutator, and armature checks. Market-specific wiring diagrams include the base electrical systems and the later de-compression and starter circuits.

Fork, Brake, and Rear-Suspension Service

Fork service includes tube inspection, seal replacement, and oil-level adjustment. The disassembly notes warn that separating the fork tubes can damage the anti-friction bushings.

Rear-suspension coverage includes swingarm and linkage bearings, shock removal and inspection, and spring-preload adjustment. Internal shock-absorber rebuilding is not covered.

Review the manufacturer’s safety procedures and warnings before teardown or diagnostic work, including the precautions for brake-fluid and fuel-system handling.

Selected Valve, Fastener, and Oil Service Data

The valve-clearance section specifies 0.08–0.13 mm for both intake and exhaust valves with the engine cold. The engine torque table lists 35–40 N·m for the 10 mm cylinder-head bolts, with separate specifications for the nuts and cover bolts.

The oil-capacity data distinguish 2,150 ml with a filter change from 2,000 ml for an oil-only change.
