Kawasaki Ultra 130 DI 2001 Jet Ski Service Manual (P/N 99924-1276-01)

Kawasaki’s factory service manual covers the 2001 JET SKI Ultra 130 D.I. (JH1100-B1). This is P/N 99924-1276-01, First Edition (1), issued March 9, 2001.

PDF Reading and Diagram Detail

Text search and wiring labels: PDF text search and embedded bookmarks are not available. Small wire-color codes, connector labels, and pin numbers in the wiring diagrams require zooming for comfortable reading.

The ZIP download contains one printable, English-language PDF with 307 pages. That total includes six front-matter pages, eight blank pages, and the rear model-application and part-number page.

DFI Troubleshooting, Engine Repair, and Jet-Pump Service

The following selected coverage highlights outline the main workshop content. Other topics include hull-fitting removal and preparation for storage, rather than a complete chapter-by-chapter listing.

• FICHT fuel system: Fuel pump, filter, pressure regulator, supply and return rails, direct injectors, throttle-body synchronization, reed-valve inspection, and fuel pressure and flow testing.

• KADIAG diagnostics: Stored-code retrieval, static component tests, cylinder-drop testing, live engine monitoring, replacement-injector registration, EMM data transfer, and controlled fuel-map adjustment.

• Engine repair: Step-by-step engine removal and installation, top-end disassembly, crankcase splitting, and reassembly, supported by inspection specifications and component wear limits.

• Jet pump and drive: Pump rebuilding, drive-shaft holder service, bearing and seal replacement, impeller shim selection, and final rotational and clearance checks.

• Electrical and steering systems: Wiring diagrams and circuit tests for dual-output charging, ignition, starter, electric trim, multifunction meter, sensors, and Kawasaki Smart Steering.

• Lubrication, cooling, and exhaust: Oil-pump bleeding and output testing, cooling and bilge flushing, and exhaust-passage cleaning and inspection.

Kawasaki designed this service manual primarily for trained mechanics in a properly equipped shop. It also supports basic maintenance and repair by owners who understand mechanics, tool use, and workshop procedures; DFI programming and precision internal work require the appropriate equipment and experience.

DFI Fault Isolation and EMM Programming

The theory section explains how the EMM coordinates injector timing, high-frequency multi-strike DC-CDI ignition, cold starting, idle control, fuel-pump operation, engine-hour recording, warning outputs, and S.L.O.W. protection. It also traces the dual-voltage charging architecture that supplies the battery and conventional circuits separately from the injectors and ignition.

Priority-coded service faults and symptom charts cover no-crank, crank/no-start, stalling, rough running, low rpm, shutdown, smoke, overheating, false warnings, and S.L.O.W. activation. Their links to component checks help distinguish fuel-delivery, ignition, sensor, and cooling faults before selecting a repair.

Dedicated tests address throttle-position, crank-position, water-temperature, air-temperature, steering-position, fuel-level, oil-level, and speed sensors. The barometric-pressure and EMM-temperature sensors are internal to the EMM and are not serviced separately.

Injector matching: Each injector’s serial number and flow characteristics are stored in the EMM. Moving an injector between cylinders or engines can upset the mixture and cause engine damage.

The manual describes replacement-injector registration and transfer of engine-specific information to a service replacement EMM. The transfer procedure requires communication with the original EMM; a noncommunicating unit requires distributor assistance. KADIAG operation also refers to the separate KADIAG Software Manual, P/N 99929-1412-01, which is not included. The download contains no diagnostic software or communication cable.

Internal Engine Inspection and Assembly

Inspection coverage includes compression testing, cylinder-head warp, cylinder and piston measurement, piston-ring checks, connecting-rod alignment, bearing condition, and crankshaft runout. Coupling and flywheel removal, stator service, and crankcase check-valve inspection are also documented.

Crankshaft disassembly is outside the manual’s scope because Kawasaki specifies specialized equipment; damaged or worn crankshaft components call for assembly replacement. Removed piston-pin snap rings must not be reused because they can come loose and score the cylinder wall.

The 15 chapters include scheduled maintenance, torque tables, special tools, and cable, wire, cooling-hose, oil-hose, and fuel-hose routing. Exploded views identify assembly order, tightening points, lubricants, sealants, and locking-agent locations.

Pump, Steering, and Electrical Workshop Detail

The pump section connects poor propulsion performance with excessive impeller clearance even when the impeller and pump case show no obvious damage. Steering- and trim-cable adjustment and Smart Steering sensor clearance and operation checks are documented separately.

Starter-motor coverage includes disassembly and inspection of brushes, the commutator, and armature. Named diagnostic illustrations include the DFI System Diagram, DFI Wiring Diagram with EMM connector pin views, EMM Power Source Circuit, Injector Circuit, Charging System Circuit, and Kawasaki Smart Steering System flow chart.

Specified service equipment: DFI tool references include Communication Cable 57001-1460, KADIAG Software 57001-1461, Needle Adapter Set 57001-1457, Throttle Sensor Setting Adapter 57001-1400, and Fuel Pressure Gauge Adapter 57001-1463. Mechanical tools include Impeller Wrench 57001-1228 and Flywheel Puller Assembly 57001-1405.

Fuel-system work can release residual pressure, while injector and ignition circuits operate at hazardous voltage. Follow the manual’s cooling-water, electrical-isolation, and fuel-handling precautions during testing and repair.

A Preview of Sensor, Injector, and Impeller Test Data

With the engine stopped and ignition on, throttle-position sensor output specifications are 0.2 ± 0.1 V DC at the specified idle opening and 3.75–4.00 V DC at full throttle.

For the FICHT injectors, the resistance-inspection section specifies 0.684–0.710 Ω at 25 °C.

Jet-pump assembly data list a standard impeller-to-pump-case clearance of 0.2–0.3 mm and a service limit of 0.6 mm. The assembly section also provides the associated shim-selection chart.
