• Official Honda publication PN C4256-90954 (1988), serving as the foundational repair reference for the vehicle launch.
• Features 262 pages of original technical documentation, including system schematics and component exploded-view diagrams.
• Indexed architecture covers every chapter and appendix for fast workshop navigation.

What the Manual Documents

This 1988 publication delivers detailed technical data across twenty-two distinct sections. Major chapters catalog components like the cylinder head, recoil starter, balancer, and crankcase assembly. Chassis documentation explores the transmission system, front and rear suspension geometry, and the hydraulic brake circuit. You will find comprehensive electrical data detailing the ignition, charging, and lighting systems alongside a complete wiring diagram. Dedicated segments for fuel component evaluation, cooling system testing, and periodic maintenance scheduling provide mechanics with exactly what they need to assess the vehicle before planning any repair. For safety, always ensure the machine is fully secured and stabilized prior to initiating any diagnostic work.

Specification Highlights

Accurate factory specifications eliminate guesswork on the shop floor. The engine cooling system capacity for the FL400R is rated at 2.04 liters. During engine assembly, the cylinder head nut torque requires a strict 27 N·m. Transmission oil capacity takes exactly 1.0 liters for complete assembly and disassembly procedures. The text also catalogs critical routine data like intake valve clearances and the factory spark plug gap. Mechanics benefit from a comprehensive list of torque values for chassis and frame hardware, notably the 55 N·m requirement for engine-transmission connecting bracket bolts.
