• 527-page original factory reference documenting complete unit specifications for the KVF400-A1 and A2 series
• Features 43 exploded-view diagrams, 16 electrical system schematics, and 57 tightening torque tables

Technical Content and System Organization

This workshop reference breaks down the liquid-cooled single-cylinder engine, chassis, and cooling systems into categorized chapters for efficient shop use. It details the 4-valve per cylinder combustion chamber, the DC-CDI ignition system, and the reverse power control setup. You will find comprehensive overviews of engine top-end service, transmission disassembly sequences, lubrication routing, and steering geometry. By providing highly specific torque tables for fasteners across the fuel system, electrical components, and engine assembly, it delivers the exact data required for accurate bench work. Always exercise proper shop safety protocols and verify vehicle stability before cross-referencing these system charts and beginning any mechanical procedures.

Specifications and Reference Values

Technical data is laid out clearly to streamline diagnostic workflows. The documentation covers engine displacement (391 mL), a compression ratio of 9.0, and precise ignition timing specs (10° BTDC @ 1300 r/min to 30° BTDC @ 4300 r/min). Technicians can easily locate essential fluid capacities, including the 3.4 L engine oil limit and 14 L fuel tank volume. Cooling system pressure testing values are set at 93–123 kPa (14–18 psi). Electrical parameters detail an alternator rated output of 25 A at 6000 r/min. Mechanical tolerances are strictly defined, listing an intake valve clearance of 0.14–0.19 mm and a 4.16–0.92 reduction ratio for the belt converter drive train.
