Suzuki GSX-R1100 Service Manual 1986–1996 (P/N 99500-39061-01E)

This Suzuki GSX-R1100 service manual, P/N 99500-39061-01E, is the June 1987 second edition of the January 1986 publication. It covers the GSX-R1100G (1986) and includes the 1986 appendix and GSX-R1100H (1987) supplement. The H-model section documents changes to use alongside the base service procedures.

PDF Search, Chapter Bookmarks and Page Gaps

Search and diagram detail: PDF text search is not available. Embedded bookmarks link to the main sections and both model appendices. Small wiring labels require zooming; some wire-color legend wording is cropped at the right edge of the base E-28 diagram.

Missing printed pages: Pages 3-47–3-48, 4-27–4-28, and 7-15 are absent from this PDF.

One printable PDF contains 295 pages total, including both covers, the five-page 1986 appendix, the 23-page H-model supplement, the publication page, and two repeated rear-brake pages.

Engine Overhaul, Carburetor Tuning and Chassis Service

The selected topics below outline the main service areas. Other examples include battery electrolyte checks and headlight adjustment.

• Engine and transmission: Engine removal, crankcase disassembly, crankshaft and connecting-rod bearing selection, transmission shaft service, and gearshift cam and fork inspection.

• Cylinder head and valve gear: Valve-guide replacement, valve-seat reconditioning, camshaft inspection, valve-clearance adjustment, cam timing, and cam chain tensioner checks.

• Fuel and lubrication: MIKUNI BST34SS carburetor disassembly, float and fuel-level checks, synchronization, fuel-cock operation, oil-pressure testing, and oil-cooler operation.

• Electrical diagnosis: Three-phase A.C. generator, regulator and rectifier tests; transistorized ignition checks; signal-generator testing; starter-motor service; and relay inspections.

• Brakes and hydraulic clutch: Pad replacement, caliper and master-cylinder service, clutch release-cylinder inspection, and step-by-step brake and clutch bleeding procedures.

• Suspension and steering: Front-fork disassembly, NEAS checks, steering-stem bearing service, steering-damper inspection, and full-floating rear-suspension linkage service.

• Troubleshooting and diagrams: Symptom-based fault charts, market-specific wiring diagrams, wire and hose routing illustrations, transmission cross-sectional views, and component exploded drawings.

Written primarily for experienced motorcycle mechanics, this manual also provides apprentice and DIY mechanics with a repair reference that calls for specified measuring equipment and special tools.

Engine Inspection and Assembly Details

Compression-test guidance and wear-limit tables help assess engine condition before an overhaul. Bearing-selection tables connect crankshaft and connecting-rod identification marks with the appropriate bearing shells, supporting parts selection during bottom-end repair.

The cylinder-head section provides step-by-step procedures for valve-guide replacement and valve-seat reconditioning. Camshaft timing illustrations, journal-holder identification, and tightening sequences support reassembly of the TSCC engine.

The manual warns that unevenly drawn-down camshaft holders can damage the head or holder thrust surfaces. It also identifies valve-guide installation practices that can damage the guide or cylinder head.

Transmission cross-sectional views show gear, washer, and circlip positions. Assembly notes address circlip replacement, orientation, and excessive expansion. Bearing-measurement cautions explain why rotating the crankshaft with Plastigauge in place invalidates the clearance reading.

BST34SS Carburetors and SACS Lubrication

The carburetor chapter explains diaphragm operation and the slow, main, starter, and float circuits. Its balancing procedures specify the carburetor balancer 09913-13121 and throttle-valve adjustment wrench 09913-14911.

Oil-pressure diagnosis distinguishes possible causes of low and high readings. The Engine Lubrication System Chart and sectional illustration trace oil distribution through the Suzuki Advanced Cooling System. Oil-filter, sump-strainer, relief-valve, and cooler information accompanies these diagrams. The oil pump is treated as an assembly, with an explicit restriction against internal disassembly.

Ignition Tests and Market-Specific Wiring

Electrical coverage extends from continuity checks to ignition-coil performance tests, ignitor-checker testing, and generator regulator/rectifier diagnosis. Engine procedures also show signal-generator stator removal and installation, plus oil-pressure-switch lead routing.

The H-model supplement adds Canadian E-28 side-stand/ignition interlock diagnosis. Its circuit diagrams and component checks help distinguish an interlock fault from other starting or ignition problems.

Forks, Brakes and H-Model Changes

NEAS coverage includes relay and solenoid-coil checks, leakage inspection, removal, and replacement. The NEAS unit is supplied as a replacement assembly; the rear shock absorber is also identified as nonserviceable internally.

The H-model section documents changes to the front axle and its matching bearings, spacers, nut, and speedometer gearbox. Revised fork-spring limits and rear-suspension settings help distinguish H-model requirements from the base specifications.

Brake and clutch chapters include hydraulic component inspection and exploded views. Follow the manual’s support and brake-fluid precautions during wheel, suspension, and hydraulic work.

Factory Adjustment and Inspection Examples

With the engine cold, the maintenance section specifies 35–40 N·m for the cylinder-head nuts and 0.10–0.15 mm clearance for both intake and exhaust valves.

Cylinder-head inspection gives a 0.05 mm valve-stem runout service limit. Valve-seat reconditioning distinguishes the 45° contact surface from the 15° upper cut.
