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

Suzuki's later change sections refer back to earlier factory chapters for unchanged procedures. Clymer adds workshop fundamentals, photo-supported repair sequences, troubleshooting, quick-reference data and an index for its narrower model range.

Factory page gaps: Printed pages 8-39, 8-40, 12-24, 12-25, 17-15, 17-16 and 17-21 are absent. The gaps include both 1993 factory wiring-diagram pages and affect earlier wiring/routing material, later DR350SE service data and rear-suspension settings.

Clymer wiring coverage: Its wiring appendix is limited to its 1990–1994 coverage and contains no model-specific 1995–1999 wiring material.

PDF Search, Bookmarks and Wiring Detail

Text search and navigation: The manual pages have no searchable text layer; only the parts-resource sheet has selectable text. The 21 bookmarks open Suzuki chapters, the resource sheet and the Clymer manual's beginning; Clymer has no chapter-level bookmarks. Small wiring labels require zooming, and sideways diagrams need rotation for comfortable reading.

One printable PDF with 797 pages total, including the one-page parts-resource sheet. The publication counts above include their covers and front matter.

Engine Overhaul, Electrical Tests and Chassis Service

These selected content highlights outline the repair coverage. Other topics include exhaust-system repair and storage preparation.

• Engine overhaul: Step-by-step removal and reinstallation, cylinder-head and valve service, camshaft and cam-chain work, crankcase separation, crankshaft and balancer inspection, and timed reassembly.

• Clutch and transmission: Clutch, kickstarter and oil-pump service, transmission inspection, and disassembly and reassembly of the internal shift mechanism.

• Fuel, lubrication and emissions: Carburetor removal, disassembly, inspection, reassembly and adjustment, fuel-cock service, dry-sump lubrication, oil-pressure checks and California evaporative-emission components.

• Electrical diagnosis: Ignition, magneto, CDI, charging, battery, lamp, instrument and switch testing, plus starter-clutch, starter-motor, generator, relay and interlock diagnosis for electric-start models.

• Chassis, brakes and suspension: 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 and shop data: Periodic schedules, tune-up procedures, cable and hose routing, troubleshooting, component-specific torque tables, fluid capacities, wear limits, running clearances, carburetor settings and electrical test specifications.

Suzuki wrote its manual primarily for experienced mechanics, while also identifying apprentice and do-it-yourself mechanics as users; Clymer adds basic tool and workshop guidance alongside its repair procedures.

Factory Changes and Market-Specific Procedures

Factory coverage separates the off-road DR350, street-legal DR350S and electric-start DR350SE. The Suzuki portion begins with the 1990 DR350 and DR350S material.

Change sections cover 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).

Electric-start and decompression: The DR350SER material adds the automatic-decompression camshaft assembly and starter/interlock circuitry. The circuit explanation and component tests support tracing a starting fault through the side-stand, neutral and clutch switches; the clutch switch applies only to U.S. and Canadian models. Suzuki treats the camshaft/automatic-decompression assembly as a replacement unit, not an internally serviceable assembly.

Market and fork differences: The final factory section distinguishes U.S., California, Canadian, U.K., French, German, Swiss, Italian, Australian, Barbados and general-market applications. Its DR350SEW/SEX fork section for U.S., Canadian and California models refers to the DR350V overhaul procedures; other market versions use a different fork configuration.

Carburetor References, Diagrams and Factory Tools

Mikuni TM33SS and BST33/BST33SS applications have separate service data and emission-control details. Model and market columns distinguish the applicable carburetor settings before parts or adjustment references are selected.

The engine lubrication-system chart and gearshift-cam and fork exploded view show oil circulation and assembly relationships. The DR350SEW/SEX front-fork exploded view shows the later fork assembly.

Electrical and routing examples include the DR350SN wiring diagram for Australia/Canada/U.S. models, DR350SER ignition/start and interlock circuitry, and California canister hose routing.

Specified tools include crankshaft installer 09910-32812, crankcase separator/crankshaft remover 09920-13120, front-fork oil-seal installer 09940-50113 and pocket tester 09900-25002.

Crankshaft and Brake-Service Cautions

Suzuki warns that tapping the crankshaft into the crankcase with a plastic hammer can disturb its alignment. The brake chapters identify caliper-piston damage from excessive air pressure and chemical damage to paint, plastic and rubber from spilled brake fluid.

Service safety: This documentation is provided for reference only. Brake hydraulic work, spring-loaded suspension service, and internal engine repair require suitable training, tools, and protective equipment; consult a qualified motorcycle technician before taking on work beyond your experience.

A Preview of Plug Gaps and Driveline Checks

For the base DR350L procedures, spark-plug inspection specifies a gap of 0.8–0.9 mm, while clutch adjustment specifies 10–15 mm of lever play.

The DR350L drive-chain inspection gives a service limit of 319.4 mm measured over 20 pitches with the chain fully tensioned.
