Technical Content and Structure

The 2000–2003 Kawasaki 900 STX service documentation provides a structured walkthrough of all primary systems. It starts with critical general information and cable routing maps. From there, subsequent chapters detail the fuel system components, including carburetors and the fuel tank assembly. You also get a thorough breakdown of the engine lubrication system, exhaust chamber, and the complete engine top end. Additional sections focus heavily on the cooling and bilge systems, the drive system with its axial flow pump, steering assembly, and full electrical schematics. If you need to map out maintenance schedules, the manual includes a specific appendix covering periodic maintenance charts for 10-hour, 25-hour, and 100-hour service intervals. Keep in mind that working on high-performance personal watercraft involves fuel vapors and high electrical currents; always ensure a well-ventilated workspace and proper battery disconnection procedures before starting your work.

Engine and Drive Specifications

This supplement delivers the hard numbers required for accurate diagnostics and routine maintenance. Engine output is rated at 74 kW (100 PS) at 6750 r/min, pushing a maximum torque value of 109.7 N·m (81.0 ft-lb). For technicians handling fuel delivery, the Keihin CDCV 33 mm carburetors list a standard #165 main jet and #38 pilot jet for sea-level operation. When dealing with the top end, the cylinder head nut torque is specified at 29 N·m (22 ft-lb). On the electrical side, the primary winding resistance for the ignition coil sits between 0.18–0.24 Ω. Ignition timing for the 900 STX is documented strictly as 15° BTDC at 1250 r/min and 25° BTDC at 3000 r/min. Down below, the drive shaft coupling bolt torque requires a solid 132 N·m (98 ft-lb). Having these exact factory specifications on hand eliminates guesswork, streamlining the entire repair workflow in a busy shop environment.
