1986-2009 Suzuki VS700, VS750 & VS800 Intruder / Boulevard S50 Service & Repair Manual with Supplements (P/N 99500-38064-03e)

This Suzuki service manual covers the 1986–2009 VS700, VS750, VS800 Intruder and Boulevard S50 range. It combines ten main workshop groups with integrated model supplements; the base-manual foreword carries Suzuki Motor Corporation’s 1990 copyright.

• Engine repair: Engine removal and reinstallation, cylinder-head service, camshaft timing, crankshaft bearing selection, and piston and cylinder inspection.

• Clutch and transmission: Hydraulic clutch servicing, plate inspection, transmission disassembly, gear assembly, and shift-fork clearance checks.

• Shaft drive: Secondary and final bevel-gear disassembly, shim adjustment, backlash measurement, tooth-contact checks, and propeller-shaft inspection.

• Fuel and cooling: Carburetor teardown and balancing, fuel-pump and relay checks, lubrication diagnosis, thermostat testing, and water-pump service.

• Electrical diagnosis: Charging, ignition, starter, and side-stand interlock tests, with wiring diagrams and model-specific harness routing.

• Chassis service: Front brake and rear drum-brake work, fork overhaul, steering-stem inspection, wheel bearings, and swingarm servicing.

Written primarily for experienced mechanics, the manual also addresses apprentice and do-it-yourself mechanics. Internal overhaul work calls for the precision measuring equipment and special tools identified in the relevant sections.

Engine, Clutch, and Transmission Repair

The engine chapters document cylinder-head disassembly, valve-guide and seat servicing, camshaft journal inspection, and piston-to-cylinder measurements. Crankshaft and connecting-rod bearing selection tables support internal engine work, alongside compression testing and component-specific wear limits.

Clutch coverage extends to the hydraulic operating system, drive and driven plates, springs, and release components. Transmission documentation includes shift-fork groove clearances and illustrated countershaft and driveshaft assembly.

The disassembly notes flag the primary-drive-gear bolt’s left-hand thread and the damage that can result from treating it as a conventional fastener.

Bevel-Gear Setup and Model Supplements

The shaft-drive chapter goes beyond oil changes. It documents secondary-gear and final-gear shimming, bearing-case clearance, backlash, and tooth-contact patterns. The final gear case breather circuit drawing explains the air and oil passages within the assembly.

Later supplements identify changes to connecting rods, pistons, crankpin bearings, intake pipes, and radiator connections. Their differences and cross-references help match the service data to the model before selecting bearings or applying a base-manual specification. These supplements build on the earlier chapters rather than repeating every repair procedure.

Carburetors, Lubrication, and Cooling

Fuel-system coverage includes needle-valve inspection, float-height and fuel-level checks, and carburetor synchronization. The balancing section identifies carburetor balancer 09913-13121 and adapter 09913-13140, with separate adjustment coverage for synchronizing cables, throttle cables, and carburetor replacement.

The lubrication system chart traces oil delivery to the engine components. Oil-pressure diagnosis distinguishes possible causes of high and low readings, while cooling coverage includes radiator-cap testing, thermostat inspection, water-pump disassembly, and fan-switch checks.

Cooling-system service carries a hot-coolant burn risk; follow the manual’s radiator-cap precautions.

Electrical Troubleshooting and Chassis Work

Electrical documentation combines symptom-based troubleshooting with charging-system, ignition-system, and starter-system circuit diagrams. The side-stand/ignition interlock diagrams and model-specific wiring layouts support fault tracing when the engine will not start or loses ignition.

The VS800GLT/V supplement includes digital ignitor checker 09931-94490 and lead wire 09931-61740. Later VS800K6 material adds a regulator/rectifier terminal-test table.

Chassis sections cover caliper and master-cylinder inspection, hydraulic bleeding, rear brake linkage, fork oil specifications, steering bearings, and suspension checks. Fork assembly cautions address damage to the Teflon-coated bushings. Exploded views, hose-routing illustrations, and fastener-specific torque tables accompany the work.

A Preview of Valve-Clearance and Fluid Specifications

These maintenance values are a small sample of the technical specifications in the manual.

The VS700 base procedures specify intake and exhaust valve clearance of 0.08–0.13 mm with the engine cold. The VS700 capacity table lists 1.7 L of coolant and 200–220 ml of final bevel-gear oil.

Model-specific service tables also distinguish engine-oil quantities for an oil change, filter change, and overhaul.

PDF Bookmarks, Search Coverage, and Page Breakdown

Finding sections and reading diagrams: Embedded bookmarks link the main workshop groups and model supplements. Text search works in the opening indexes and later VS800 supplements, while most earlier workshop pages are not searchable. Small wiring-diagram labels require zooming.

Supplied as one printable, English-language PDF with 539 pages: 6 opening pages, 270 pages covering the ten main groups, and 263 pages of integrated model supplements. All 14 blank separator pages are included in that total.
