Supplied as a single printable English-language 442-page PDF, including the cover, two introductory pages, 11 memo pages and the two-page index.

Engine, Driveline and ESP Service Coverage

These selected service topics illustrate the repair coverage. Other documented work includes reverse-lock adjustment and carburetor-heater testing.

• Engine repair: Step-by-step instructions for engine removal, cylinder-head and valve service, camshaft work, and cylinder/piston disassembly, inspection and installation.

• Clutch and transmission: Centrifugal and change-clutch overhaul, gearshift-linkage service, crankcase separation, transmission inspection, and crankshaft/balancer installation.

• Fuel and lubrication: Carburetor disassembly and reassembly, pilot-screw and high-altitude adjustments, oil-pump inspection, oil-cooler service, and cooling-fan removal.

• Final drives: FM/FE front-drive-shaft and differential service, rear axle and final-drive overhaul, backlash checks, and gear-tooth contact-pattern inspection.

• Brakes and chassis: Front hydraulic drum-brake bleeding, master- and wheel-cylinder service, rear brake repair, wheel bearings, suspension arms, and swingarm service.

• Electrical testing: Battery and charging-system diagnosis, ignition peak-voltage checks, starter-motor inspection, and model- and market-specific wiring diagrams.

• TE/FE Electric Shift Program: Blink-code troubleshooting, angle-sensor tests, shift and reverse-switch checks, control-motor inspection, and reduction-gear service.

Suited to mechanically qualified owners and technicians with the required workshop tools; the maintenance schedule recommends that only a Honda dealer service the steering system and steering-shaft holder bearing.

Engine Access and Clutch Differences

Repair planning: Cylinder and piston work can be performed with the engine in the frame. Camshaft, transmission and crankshaft service require engine removal; transmission and crankshaft work also require crankcase separation. The alternator/starter-clutch section describes swingarm removal as an alternative access route when no additional engine work is needed.

Clutch variants: TE/FE change clutches use a judder spring, spring seat and a distinct outer clutch disc. The assembly drawings and inspection tables distinguish these parts from the TM/FM arrangement.

Carburetor Service and Dry-Sump Lubrication

VE94EA carburetor specifications accompany vacuum-piston and diaphragm inspections, air cut-off valve testing and jet service. The float-level inspection specifies gauge 07401-0010000; the float is not adjustable and is replaced as an assembly if its level is outside specification.

The integral crankcase oil tank is explained through the Oil Management System Drawing and Lubrication System Diagram, which trace feed and scavenge paths. The oil-level check accounts for circulation through this dry-sump system.

The oil-filter replacement section warns that installing the filter backward can cause severe engine damage.

Differential Setup and Chassis Details

A.P. Suretrac differential: FM/FE procedures cover face cams, cam followers, cone-spring inspection and slip-torque testing. Shim-selection information and gear-tooth contact-pattern views distinguish drive-side and coast-side contact during differential and final-drive setup.

Steering and brakes: Alignment information distinguishes TM/TE toe-in from FM/FE toe-out. Brake coverage includes waterproof-seal inspection and replacement. Cable & Harness Routing drawings show the specified paths around covers and brackets, helping avoid pinched wiring during reassembly.

ESP Fault Tracing and Electrical Checks

The ESP System Diagram, blink-code table and connector tests help separate sensor, harness and control-motor faults from mechanical shifting problems. The shift control motor is replaced as an assembly; angle-sensor and reduction-gear procedures are documented separately.

Charging diagnosis includes current-leakage and regulator/rectifier harness tests. Ignition diagnosis compares pulse-generator readings at the ICM and alternator connectors. ESP service notes warn that disconnecting powered connectors can damage the ECU.

Before diagnostic work, review the manual’s safety procedures and shop precautions, particularly those for gasoline handling and electrical isolation.

A Preview of Head-Fastener and Differential Service Data

Cylinder-head installation specifies 39 N·m (29 lbf-ft) for the cap nuts, with oiled threads and seating surfaces. The procedure distinguishes these nuts from the rocker-arm holder bolt and specifies staged, crisscross tightening.

For FM/FE front-differential service, the listed oil quantities are 241 cm³ after draining and 275 cm³ after disassembly, distinguishing routine oil replacement from refilling a dismantled assembly.
