2003 Honda ST1100P Service Manual Addendum (P/N 61MY311)

This two-PDF factory service set combines Honda's 2003 ST1100P Service Manual Addendum with the base ST1100/ST1100A shop manual it requires. The addendum is specific to the 2003 ST1100P, while the included base manual covers the 1991-2002 ST1100 and 1992-2002 ST1100A. Honda states that these manuals are written for readers who have already acquired basic knowledge of Honda motorcycle maintenance, making the material best suited to technicians and experienced owners who are comfortable with factory repair procedures and specialty tools.

• 472-page PDF set: ST1100/ST1100A Shop Manual No. 61MY311, 441 PDF pages; 2003 ST1100P Service Manual Addendum, issued October 2003, 31 PDF pages.
• Engine and drivetrain repair covers engine removal and installation, cylinder-head removal and disassembly, valve-clearance service, timing-belt and pulley work, clutch overhaul, transmission and primary-damper service, crankcase separation, piston/crankshaft work, and final-drive setup.
• Chassis and brake procedures include body panels and exhaust, handlebar and anti-dive work, rear-wheel disassembly, shock absorber and swingarm service, brake master cylinders and calipers, LBS bleeding, the secondary master cylinder, delay valve, and proportional control valve.
• ABS/TCS diagnosis is divided between 1992-1995 ABS/TCS and post-1995 LBS-ABS/TCS systems, with circuit diagrams, pre-start self-diagnosis, problem-code retrieval and clearing, Symptom-to-System charts, wheel-sensor air-gap inspection and shim adjustment, and front/rear modulator replacement.
• Fuel, cooling, and electrical coverage includes carburetor separation and overhaul, synchronization, pilot-screw and high-altitude adjustment, PAIR/EVAP controls, radiator and water-pump service, charging-system tests for early and later builds, ignition fault tracing, starter service, and lights/meters/switches checks.
• ST1100P body and equipment procedures detail the seat and seat cowlings, saddlebag and amplifier stays, fairing pockets, instrument panel, rearview mirror and front strobe-lamp stay, headlight aim, rear lighting, and voltmeter removal and bulb replacement.
• Police cable and harness documentation provides seven printed routing pages for the bank-angle sensor, siren speaker, strobe lamp, headlight and voltmeter relays, police switch groups, optional-equipment connectors, and the associated fuel, ignition, EVAP, and PAIR routing, followed by a full ST1100P wiring diagram. The base manual adds 20 printed routing pages for Standard, ABS/TCS, and LBS-ABS/TCS configurations.

Police-Specific Data

The addendum supplies 11 printed pages of ST1100P specifications rather than repeating the full repair manual. They cover general dimensions and configuration, engine and fuel data, cylinder-head and rotating-assembly limits, transmission and clutch specifications, cooling and final-drive data, suspension and brake limits, and electrical test values. Model-identification locations are shown for the VIN, engine, frame, carburetors, and color label. Emissions references include the information-label locations, the high-altitude update label, and the California vacuum-hose routing diagram.

Diagnostic Reference and Special Tools

The base manual goes well beyond routine maintenance. ABS and TCS chapters provide system wiring locations, connector and terminal views, circuit diagrams, indicator-light code tables, diagnostic flowcharts, wheel-sensor checks, and post-repair self-diagnosis. Other useful graphics include the cooling-system flow pattern, standard-model wiring diagrams by production period, the TCS circuit diagram, the LBS hydraulic layout, and the complete ST1100P electrical schematic.

Honda's tool table identifies the equipment needed for deeper repair work, including valve spring compressor 07757-0010000, pinion joint holder 07924-ME40000, pinion retainer wrench 07910-MA10100, oil seal driver 07965-MC70100, and shock absorber compressor 07GME-0010000. The manuals also provide component-specific torque tables, capacities, pressure-test data, bearing-selection references, wear limits, clearances, adjustment data, and electrical specifications.

Scope Notes Before You Buy

The ST1100P addendum is not a stand-alone manual; it supplies Police-model differences and directs the reader to No. 61MY311 for procedures and data not repeated there. This set includes that model-specific base manual, but it does not include Honda's separate Common Service Manual. Generic procedures such as tire removal and remounting, battery testing and charging, oil-pressure checks, selected switch and sensor tests, standard brake bleeding, and portions of final-drive backlash and tooth-contact inspection are cross-referenced to that publication.

The 441-page base PDF contains three exact duplicate scan pages and omits printed page 5-7 plus section 13 pages 13-9 through 13-30. The missing section removes the end of the LBS front-wheel removal procedure and the front-wheel disassembly, fork removal/disassembly/assembly, and steering-stem procedures listed in the printed contents; those procedures are not present in this file.

The cautions are assembly-specific. The cylinder-head section warns that rotating the camshafts after timing-belt removal can damage the valves and piston domes; the crankcase section explains that incorrectly positioned bearing inserts can block oil passages and lead to engine seizure. Brake, cooling, fuel, and electrical work can involve pressurized fluid, hot coolant, gasoline vapors, or sudden motor operation, so the model-specific safety notes and required test equipment should be followed throughout any repair.
