2003 Honda ST1100P Service Manual Addendum (P/N 00302-MJ4-3300)

• Official Honda publication 00302-MJ4-3300, dated October 2003.
• Designed to be used alongside the base 61MY311 shop manual, this addendum provides essential supplemental data for the ST1100 platform.
• Bridges the gap between standard civilian models and police-edition variants, documenting specialized chassis, electrical, and cooling configurations.
• Includes 13 pages of highly detailed cable and harness routing maps covering Standard, ABS/TCS, and LBS-ABS/TCS setups.
• Contains 47 pages of service specifications. You will find everything from precise torque values to diagnostic thresholds.

Component and System Coverage

Servicing a police-edition ST1100 requires exact knowledge of its unique bodywork and electronics. This manual details the specialized procedures for managing the seat, cowlings, saddlebag stays, and instrument panel. Dedicated chapters break down internal components. Expect comprehensive teardown references for fairing pockets, rearview mirror assemblies, and the complex integration of emergency lighting and electrical switching units.

Wiring is where the P-model significantly differs from the base version. The text maps out routing for specialized police cabling, including bank angle sensors, siren relays, and model-specific harnesses. Getting the alignment right is crucial. The documentation clarifies the exact removal sequences for fairing panels and internal instrumentation exclusive to the ST1100P build, ensuring accurate maintenance for cooling and fuel systems under heavy duty cycles.

Specification and Data Highlights

Precision matters when working on the V4 engine platform. This addendum delivers a full technical database covering engine internal clearances, valve timing, and hydraulic system pressures. Cylinder head bolt torque values are strictly documented at 58 N·m (42 lbf·ft). Crankshaft main journal oil clearance is set between 0.026 and 0.048 mm.

Cooling system data dictates a capacity of 2.5 liters for the radiator and engine, with the thermostat opening right at 80–84°C (176–183°F). You will also find baseline electrical reference data, such as stator coil resistance marked at 0.22–0.26 ohms at 20°C, and tire pressure specs calling for 250 kPa up front and 290 kPa in the rear.

Working with high-pressure hydraulics and specialized electrical systems carries inherent risks. Always verify your tools are calibrated and confirm you fully understand the mechanical procedures to avoid personal injury or equipment damage.
