Kawasaki KLX250 / D-Tracker X 2009 Service Manual (P/N 99924-1392-02)

Kawasaki’s service manual for the 2009 KLX250 (KLX250S9F) and D-Tracker X (KLX250V9F), P/N 99924-1392-02, covers maintenance, diagnosis, and repair. This is Second Edition (1), dated June 10, 2008, with regional information for Indonesia (IN), Thailand (TH), and Europe (EUR).

Searchable Text, Bookmarks and Wiring Detail

Text search and diagram labels: Body text is searchable, and embedded bookmarks provide chapter and subsection navigation. Labels within image-based diagrams and flowcharts are not searchable. Small labels in the regional wiring diagrams require zooming to read clearly.

The ZIP download contains one printable English-language PDF with 552 pages, including six unnumbered front/back-matter pages, nine blank pages, and one numbered placeholder page immediately before the IN wiring diagrams.

DFI Diagnosis, Engine Repair and Chassis Service

The following highlights are a selection of the manual’s contents. Other topics include air-cleaner servicing and TH-market evaporative-emission system checks.

• DFI and fuel delivery: Self-diagnosis, service-code interpretation, sensor and actuator testing, injector checks, fuel-pump diagnosis, fuel-pressure and flow testing, and throttle-body service.

• Engine repair: Step-by-step engine removal and installation, cylinder-head and camshaft-chain work, valve-guide and valve-seat repair, and piston and cylinder inspection.

• Clutch and transmission: Crankcase disassembly, crankshaft and connecting-rod checks, transmission disassembly and inspection, balancer timing, starter-clutch service, torque-limiter inspection, and clutch-plate assessment.

• Cooling and lubrication: Cooling-system pressure testing and flushing, water-pump mechanical-seal replacement, radiator and thermostat inspection, oil-pump disassembly, oil-screen service, and oil-pressure and relief-valve checks.

• Chassis service: Wheel, tire, hub-bearing, chain, and sprocket procedures; brake-caliper and master-cylinder overhaul; brake bleeding; fork disassembly and oil changes; shock adjustment; and swingarm, Uni-Trak linkage, and steering-stem service.

• Electrical diagnosis: Ignition, charging, starter, meter, fan, and lighting tests, supported by regional wiring diagrams, component circuits, connector information, and troubleshooting charts.

This factory service manual was written primarily for trained mechanics working in a properly equipped shop. Kawasaki also provides information for owners performing basic maintenance and repair, provided they understand mechanics, tool use, and workshop procedures; work beyond their experience belongs with a qualified mechanic.

Model and Regional Differences

The factory tables keep chassis and engine-control specifications separate for the two models. Entries distinguish final-drive gearing, tire fitment, suspension travel, dimensions, and ignition advance, which matters when selecting D-Tracker X data rather than KLX250 settings.

ECU identification: The table lists 21175-0167 for EUR and the TH-market KLX250S, 21175-0168 for KLX250V, and 21175-0224 for IN. Kawasaki warns against interchanging these ECUs because their characteristics correspond to different regulatory requirements. This is an IN/TH/EUR edition, rather than a US- or Canada-specific publication.

DFI Fault Isolation and Throttle-Body Limits

The Keihin DFI section identifies ECU terminals and the Kawasaki Diagnostic System connector. It combines FI-indicator code reading with power-supply, ground, wiring, sensor-input, and output tests, allowing component faults to be distinguished from circuit problems.

The diagnostic coverage includes the main-throttle, inlet-air-pressure, inlet-air-temperature, water-temperature, crankshaft, speed, vehicle-down, and subthrottle sensors. Injector audible checks, relay tests, resistance specifications, and peak-voltage measurements extend the testing beyond code retrieval.

Regional service codes: Assignments 32 and 62 are reversed between IN and TH/EUR configurations for the subthrottle sensor and actuator. The tables also address the fuel-pump relay, ignition coil, radiator-fan relay, air-switching valve, and oxygen-sensor heater.

Factory-set components: Throttle-body removal, cleaning, and selected component service are documented. Kawasaki prohibits disassembly or adjustment of the factory-set throttle sensors, subthrottle actuator, and throttle-link mechanism; the testing coverage should not be read as permission to recalibrate these parts.

Workshop References, Tools and Repair Cautions

Illustrations include the DFI System Wiring Diagram, DFI Diagnosis Flow Chart, Self-Diagnosis Flow Chart, Coolant Flow Chart, and Engine Oil Flow Chart. Exploded assembly views and cable, wire, and hose-routing drawings support reassembly alongside the component-specific torque tables, locking-agent callouts, capacities, clearances, and wear limits.

Specified tools include the Hand Tester 57001-1394, Fuel Pressure Gauge Adapter 57001-1593, and Throttle Sensor Setting Adapter 57001-1538. Mechanical service references include the Valve Spring Compressor Assembly 57001-241 and Fork Oil Level Gauge 57001-1290.

Cam-chain and valve-shim cautions: Kawasaki warns that partially loosening and retightening the non-return tensioner can damage the tensioner and chain, while crankshaft rotation with the tensioner removed can disturb timing and damage valves. The valve-clearance section also explains how shim stock beneath a shim or grinding a shim can cause ejection or fracture and extensive engine damage.

DFI fuel-line work can release residual pressure, while brake bleeding and engine removal introduce fluid-handling and lifting hazards. These operations require the specified equipment and factory safety precautions.

Fuel-Pressure and Injector Test Examples

The high-pressure fuel-line specification is 294 kPa (43 psi) with the engine idling, paired with a fuel-pressure inspection procedure.

For injector electrical testing, the specified resistance is approximately 9.97–11.03 Ω at 20°C (68°F). The related diagnostic section also documents injector power-supply and output-voltage checks.
