Kawasaki FD440V, FD501V, FD590V, FD611V V-Twin Gasoline Engine Service Manual (P/N 99924-2041-02)

This Kawasaki service manual covers FD440V, FD501V, FD590V, and FD611V 4-stroke liquid-cooled V-twin gasoline engines. Publication P/N 99924-2041-02, July 1999, 2nd Edition includes the FD440V–FD611V supplement, which must be used alongside the main service chapters for the revised specifications and procedures.

Text search, navigation, and wiring detail: PDF text search is unavailable, and there are no embedded bookmarks. Small wire-color codes and connector labels require zooming.

• Engine top end: Compression testing, cylinder-head removal, valve seat repair, piston inspection, and cylinder boring and honing procedures.

• Camshaft and crankshaft: Crankcase splitting, timing-gear alignment, connecting-rod inspection, crankshaft wear checks, and model-specific crankpin resizing information.

• Fuel and governor: Carburetor adjustments, high-altitude jet selection, governor link mechanism service, and mechanical fuel pump pressure and delivery tests.

• Cooling system: Leak and pressure testing, radiator inspection, thermostat testing, coolant air bleeding, and water pump disassembly and mechanical-seal service.

• Lubrication system: Oil-pressure diagnosis, pump rotor clearance checks, relief-valve inspection, oil screen cleaning, and oil filter maintenance.

• Electrical repair: Charging and ignition tests, starter-circuit diagnosis, starter motor disassembly and inspection, wiring diagrams, and electrical schematics.

Written primarily for trained mechanics in a properly equipped shop, this manual also supports basic maintenance and repair by owners who understand mechanical fundamentals, proper tool use, and workshop procedures.

Cylinder Head and Internal Engine Repair

Factory data distinguish the FD440V/FD501V valve clearances and wear limits from those for FD590V/FD611V. Inspection tables cover valves, valve springs, rocker arms, piston ring end gaps, and crankshaft main journals, alongside component-specific torque and locking-agent references. Exploded views mark fastener torques and lubrication points.

Cylinder boring and honing procedures include oversize piston data. Valve seat refacing is supported by cutter and holder references, while camshaft installation drawings show timing-gear alignment.

The valve seat repair notes explain how excessive cutting can sink the valve into the head until clearance adjustment is no longer possible, requiring cylinder-head replacement.

Crankpin resizing: For FD590V/FD611V, the manual supplies crankpin regrinding dimensions for a repair shop. FD440V/FD501V procedures call for crankshaft replacement when the journal diameter falls below its service limit, with no undersize connecting-rod option.

Carburetors and Governor Linkage

Carburetor specifications identify Mikuni BV20-15 for FD440V, BV24-18 for FD501V/FD590V, and BV26-18 for FD611V.

The Fuel and Air Flow diagrams explain the main and pilot circuits. Float-level inspection, throttle and choke adjustments, and governor arm-to-shaft setup accompany the fuel pump tests. Fuel shut-off solenoid testing is specified for FD501V/FD590V.

Water Pump, Radiator, and Thermostat

Pump inspection distinguishes coolant leaking through the mechanical seal from oil leaking through the oil seal, helping identify which seal needs attention before parts are ordered. Cross-sectional drawings show the seal cartridge, mating ring, and impeller assembly.

Radiator-cap testing and thermo-switch checks complement the cooling-system leak procedures. The safety precautions address rotating components, flammable fuel, and burns from hot, pressurized coolant.

Oil Flow and Maintenance References

The Engine Oil Flow Chart – FD590V shows the lubrication circuit. Pump inspection covers rotor and housing wear, with separate checks for the relief valve and oil-pressure warning system.

Periodic maintenance charts include oil and filter service. The supplement revises oil capacities, maintenance information, and other service specifications used with the main chapters.

Wiring, Ignition, and Starter Troubleshooting

The supplement supplies separate Wiring Diagram (FD440V) and Wiring Diagram (FD501V/FD590V/FD611V) pages. Wire-harness views identify connector terminals and lead colors; regulator and igniter resistance charts support component diagnosis.

Igniter testing specifies Kawasaki Hand Tester 57001-1394. The manual warns that a megohmmeter or a meter with a large-capacity battery can damage the igniter.

Starter coverage extends to the No-Load Starter Draw Bench Test, brush and armature inspection, and pinion-clutch checks. The Engine Troubleshooting Guide and Starter Motor Troubleshooting Guide address hard starting, power loss, excessive fuel or oil consumption, and starter engagement faults.

English PDF with Included Supplement

A single printable, English-language 178-page PDF contains 124 pages of main service chapters, the 40-page FD440V–FD611V supplement, seven cover and introductory/reference pages, and seven blank pages. All are included in the total.
