Providing a structural breakdown of the engine assembly, suspension configuration, electrical architecture, fuel delivery, and brake systems, the manual documents how the People 125 and 150 platforms maintain consistent mechanical operation across distinct displacement categories. Cataloging major assemblies into systematic removal, inspection, and reinstallation procedures, each section correlates component relationships, lubrication requirements, and fastener sequencing. The documentation establishes baseline specifications for compression pressure (125cc: 13 kg/cm²; 150cc: 15 kg/cm²), idle speed (1700±100 rpm), and spark plug gap (0.6–0.7 mm). The document includes wiring diagrams for both displacements, routing schematics for fuel lines and brake fluid conduits, and cable management illustrations.
The troubleshooting chapter addresses common diagnostics through systematic inspection steps, covering starting failures, power delivery anomalies, charging system faults, and brake performance degradation. Cooling system maintenance is addressed in the lubrication section, documenting oil capacity (0.91 liter at disassembly; 0.81 liter at service), pump specifications, and bearing clearance limits (rotor clearance: 0.12 mm maximum). Testing requirements are specified for compression measurement, ignition timing verification (using timing light methodology), and electrical resistance checks across the charging circuit. Clearance measurements are addressed for valve guides (0.10–0.037 mm intake; 0.030–0.057 mm exhaust), piston-to-cylinder tolerance (0.010–0.040 mm), and bearing play thresholds. Special procedures are addressed for brake system bleeding, final reduction gear oil changes, and drive belt tension assessment.
The manual documents torque specifications for the engine assembly, including cylinder head nuts (2.0 kg-m), clutch components (5.5 kg-m outer nut), and final reduction case bolts (1.2 kg-m for transmission cover attachment). Valve rocker arm clearance adjustment is referenced with the provision of specialized tool requirements (valve wrench E012). Front and rear suspension components are documented with mount bolt specifications (front shock: 2.0–2.5 kg-m; rear shock upper: 4.0 kg-m, lower: 2.5 kg-m). The fuel system section catalogs carburetor disassembly, jet identification (main jet #108 for 125cc, #110 for 150cc; slow jet #35 for both), and float level measurement at 17.5–18.5 mm. Brake system documentation includes master cylinder specifications, caliper piston dimensions, and disk runout limits (0.3 mm maximum). Electrical system specifications encompass battery capacity (12V-6AH), A.C. generator resistance ranges (lighting coil: 0.1–1.0 Ω; charging coil: 0.2–1.2 Ω), and regulator/rectifier voltage limits (13.5–15.5 V at 5000 rpm).
This manual documents torque specifications for engine fasteners to ensure proper vibration dampening and mechanical stability throughout the powertrain assembly.
