2009 Kawasaki KLX250 / D-Tracker X Service Manual (P/N 99966-1011–02)

• Factory model application: Covers the 2009 KLX250S9F (KLX250) from frame numbers JKALX250S□DA00001, JKALX250SSDA00548, or LX250S-A00540, and the 2009 KLX250V9F (D-Tracker X) from LX250V-A00832. The square symbol identifies a frame-number digit that varies by motorcycle.
• DFI diagnosis and fuel-system service: Details the Keihin DFI layout, Kawasaki Diagnostic System connector, ECU self-diagnosis, service-code reading and clearing, sensor and actuator checks, injector testing, fuel-pump diagnosis, fuel-pressure and flow testing, and throttle-body service.
• Engine and drivetrain repair: Covers engine removal and installation, cylinder-head and camshaft-chain work, valve-guide and valve-seat repair, piston and cylinder inspection, crankcase disassembly, crankshaft and connecting-rod checks, six-speed transmission service, balancer timing, starter clutch, torque limiter, and clutch-plate inspection.
• Cooling and lubrication work: Provides coolant pressure testing and flushing, water-pump and mechanical-seal replacement, radiator and thermostat inspection, engine-oil flow information, oil-pump disassembly, oil-screen service, oil-pressure measurement, and relief-valve inspection.
• Chassis procedures: Includes wheel, tire, hub-bearing, chain, and sprocket service; brake caliper and master-cylinder overhaul; brake-line bleeding; front-fork oil change and disassembly; shock adjustment; swingarm and Uni-Trak linkage bearing work; and steering-stem service.
• Document identity and technical illustrations: A 552-page PDF, Kawasaki Part No. 99924-1392-02, Second Edition (1), dated June 10, 2008. It contains IN-, TH-, and EUR-model wiring diagrams, a DFI system wiring diagram, DFI diagnosis flow charts, coolant and engine-oil flow charts, assembly exploded views, and cable, wire, and hose-routing drawings.

This factory service manual was written primarily for trained mechanics working in a properly equipped shop. Kawasaki also states that it contains enough basic information for an owner with mechanical knowledge, proper tools, and workshop experience to perform basic maintenance and repair; work beyond the owner’s experience should be left to a qualified mechanic.

Model and Configuration Coverage

The KLX250S9F and KLX250V9F share the liquid-cooled, four-valve single-cylinder engine and DFI architecture, but the factory tables keep their chassis and engine-control specifications separate. Model-specific entries distinguish final-drive gearing, tire fitment, suspension travel, dimensions, and ignition advance, which is especially important when using the D-Tracker X data rather than the KLX250 settings.

Regional coverage is identified as Indonesia (IN), Thailand (TH), and Europe (EUR). The ECU table specifies 21175-0167 for EUR and the TH-market KLX250S, 21175-0168 for the KLX250V, and 21175-0224 for IN. Kawasaki warns against mixing these ECUs because their characteristics correspond to different regulatory requirements. No US- or Canada-specific wiring diagram or model application is included.

DFI and Electrical Diagnosis

The fuel-injection chapter supports fault isolation at component and circuit level. Its self-diagnosis table covers the main throttle, inlet-air-pressure, inlet-air-temperature, water-temperature, crankshaft, speed, vehicle-down, and subthrottle sensors, along with the injector, fuel-pump relay, ignition coil, radiator-fan relay, air-switching valve, and oxygen-sensor heater. Service-code assignments 32 and 62 change between IN and TH/EUR configurations, a regional distinction that matters before following a test chart.

Testing goes beyond code retrieval. The manual provides ECU terminal identification, power and ground checks, sensor input and output tests, resistance and peak-voltage specifications, an injector audible check, and dedicated circuits for the ECU power supply, fuel pump, ignition, charging, starter, meter, fan, and lighting systems.

Factory Procedures, Tools, and Repair Cautions

Across the chapters, removal, inspection, assembly, and adjustment procedures are paired with component-specific torque tables, locking-agent callouts, capacities, clearances, wear limits, and electrical test specifications. Named factory tools include the Hand Tester 57001-1394, Fuel Pressure Gauge Adapter 57001-1593, Throttle Sensor Setting Adapter 57001-1538, Valve Spring Compressor Assembly 57001-241, and Fork Oil Level Gauge 57001-1290.

The manual specifically warns that partially loosening and retightening the non-return camshaft-chain tensioner can damage the tensioner and chain. Rotating the crankshaft while that tensioner is removed can also upset cam timing and damage the valves. Its valve-clearance section cautions against placing shim stock beneath a valve shim or grinding a shim, since either practice can lead to shim ejection or fracture and extensive engine damage.

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