1990–1999 Suzuki DR350 / DR350S / DR350SE Service Repair Manual (P/N 99500-43019-03E)

This 797-page PDF combines three distinct items: a 411-page Suzuki factory service manual section, a one-page microfiche/parts-catalog link sheet, and the 385-page Clymer M476 manual. The Suzuki publication carries Part No. 99500-43019-03E; its cover is dated October 1990, while the closing publication record identifies the Suzuki manual as the 11th edition from July 1999, with the first edition issued in March 1990. The Clymer volume is the fifth printing from July 2004. Suzuki states that its manual was produced primarily for experienced mechanics, while also identifying apprentice and do-it-yourself mechanics as users.

• Engine and transmission repair: Documents engine removal and remounting, full disassembly, cylinder-head and valve service, camshaft and cam-chain work, crankcase separation, crankshaft and balancer inspection, oil-pump service, clutch and kickstarter repair, transmission inspection, and timed engine reassembly.
• Fuel, lubrication, and emissions: Covers the Mikuni TM33SS and BST33/BST33SS carburetor applications, including removal, disassembly, inspection, reassembly, adjustment, and emission-control components. Fuel-cock service, oil-pressure checks, dry-sump lubrication, and California evaporative-emission hardware are also addressed.
• Electrical diagnosis and electric-start systems: Provides ignition, magneto, CDI, charging, battery, lamp, instrument, and switch testing. The DR350SER material adds starter-clutch, starter-motor, generator, relay, and side-stand/ignition-interlock diagnosis.
• Chassis, brake, and suspension work: Details wheel and bearing inspection; brake-pad, caliper, master-cylinder, hose, and disc service; hydraulic bleeding; front-fork and steering-stem overhaul; and rear wheel, swingarm, linkage, and shock inspection, reassembly, and adjustment.
• Maintenance, troubleshooting, and shop data: Includes periodic schedules, tune-up procedures, cable and hose routing, fault-finding guidance, component-specific torque tables, fluid capacities, wear limits, running clearances, carburetor settings, and electrical test specifications.

Exact Model and Market Coverage

The Suzuki portion begins with the 1990 DR350 and DR350S material, then adds cumulative change sections for DR350M/SM (1991), DR350N/SN (1992), DR350P/SP (1993), DR350R/SER (1994), DR350S/SES (1995), DR350T/SET (1996), DR350V/SEV (1997), and DR350W/X plus DR350SEW/SEX (1998–1999). These codes separate the off-road DR350 line from the street-legal DR350S and electric-start DR350SE variants. Later year sections cover only what changed and refer back to the earlier sections for unchanged repair procedures.

The 1994 DR350SER chapter is especially distinct: it covers the automatic-decompression camshaft assembly plus electric-start and interlock diagnosis and repair. The 1998–1999 material identifies separate market codes for the U.S., California, Canada, U.K., France, Germany, Switzerland, Italy, Australia, Barbados, and general-market machines, including a different DR350SEW/SEX front-fork configuration for U.S., Canadian, and California applications.

Clymer M476 and Identification Data

The separate Clymer manual covers DR250 for 1990–1993 and DR250S, DR350, and DR350S for 1990–1994. Its introduction specifies U.S. DR250/DR350 coverage and U.K. DR350/DR350S coverage. It adds workshop fundamentals, photo-supported repair sequences, troubleshooting, quick-reference data, an index, and model-specific wiring diagrams. For U.S. DR350 identification, its frame-number table uses prefix JS1DJ41A for off-road models and JS1SK42A for street models, paired with L/M/N/P year codes and start number 21000001; end numbers are not supplied. Separate U.K. DR350S starts are listed through 1993, while the 1994 entries are marked unavailable.

Diagrams and Factory Tools

Representative visuals include the engine lubrication-system chart, gearshift-cam and fork exploded view, DR350SN wiring diagram for Australia/Canada/U.S. models, DR350SER ignition/start and interlock circuitry, California evaporative-emission canister routing, and the DR350SEW/SEX front-fork exploded view. The Suzuki tool pages identify equipment by number, including crankshaft installer 09910-32812, crankcase separator/crankshaft remover 09920-13120, front-fork oil-seal installer 09940-50113, and pocket tester 09900-25002.

Scan Scope and Repair Cautions

The factory section is not page-complete: numbered pages 8-39, 8-40, 12-24, 12-25, 17-15, 17-16, and 17-21 are absent. That removes two 1993 factory wiring-diagram pages and portions of later routing, service-data, and rear-suspension material. Clymer's wiring appendix is limited to its 1990–1994 model coverage; it contains no 1995–1999 wiring material. The separate parts-resource page contains web links only; no parts catalog or microfiche images are embedded.

Suzuki's repair cautions warn that tapping the crankshaft into the crankcase with a plastic hammer can disturb its alignment and that excessive air pressure can damage brake-caliper pistons. The brake chapters also flag chemical damage to paint, plastic, and rubber from spilled brake fluid.
