2000s KYMCO People 125 / 150 Scooter Service & Repair Manual

This KYMCO service manual covers 2000s-era People 125 and People 150 scooters with carbureted, air-cooled four-stroke engines. Coverage runs from scheduled maintenance to internal engine, drivetrain, chassis, and electrical repair.

Text search, navigation, and wiring detail: Service text is searchable, and bookmarks link all 17 chapters. Labels inside the two main wiring diagrams are not searchable. Small wiring labels require zooming, and some fine wire codes remain blurred.

• Engine repair: Engine removal and installation, cylinder head and valve service, piston inspection, crankcase separation, and crankshaft checks.

• CVT and final reduction: Drive and driven pulley service, clutch disassembly, kick-starter repair, gear inspection, and transmission bearing replacement.

• Fuel system: Carburetor overhaul, auto bystarter testing, vacuum chamber and air cut-off valve service, float inspection, and auto fuel valve checks.

• Brakes and chassis: Hydraulic brake bleeding, master-cylinder and caliper service, rear drum-brake repair, suspension inspection, and steering stem ball race replacement.

• Starting and charging: Starter motor and starter clutch teardown, starter relay tests, A.C. generator removal, and regulator/rectifier diagnosis.

• Electrical troubleshooting: Ignition coil, pulser coil, and CDI unit tests, model-specific wiring diagrams, switch checks, and instrument troubleshooting.

This manual is suited to mechanics familiar with scooter teardown and electrical testing who have the specified pullers, spring compressors, and measuring equipment.

Engine Service and Lubrication

The cylinder head, valves, cylinder, and piston can be serviced with the engine installed in the frame. Crankcase separation and crankshaft work require engine removal.

Top-end coverage includes camshaft and rocker-arm inspection, valve-guide checks, cam-chain timing, and piston-ring installation. Separate inspection tables distinguish the two engine variants, including their cylinder, piston, and camshaft wear specifications.

The maintenance schedule is supported by lubrication-point illustrations, engine and frame torque tables, valve-clearance data, compression specifications, and engine- and gear-oil capacities. Oil-pump procedures cover removal, rotor-clearance inspection, assembly, and replacement at the service limit.

Carburetor Variants and Fuel-System Repair

The fuel-system specifications distinguish the VE052A carburetor for the 125cc model from the VE054A for the 150cc model, with separate jetting and pilot-screw data. These identifiers help match the reference data to the installed carburetor before parts are selected.

Auto bystarter operation and resistance checks accompany service procedures for the vacuum chamber, air cut-off valve, and float chamber. Fuel tank removal, fuel-unit service, and vacuum-operated auto fuel valve testing are also covered.

The carburetor cautions identify compressed-air cleaning as a potential cause of vacuum-diaphragm damage. Float-valve inspection and float-level measurement receive their own coverage.

Drive Pulleys, Clutch, and Final Reduction

The drive and driven pulley procedures extend to weight rollers, clutch shoes, driven-face bearings, oil seals, and kick-starter components. Final reduction repair covers the drive shaft, countershaft, final gear, bearing replacement, and case assembly.

The special-tool table identifies the E027 clutch spring compressor and E002 flywheel puller, with references to the relevant service sections.

Brakes, Suspension, and Bodywork

Hydraulic brake coverage extends beyond bleeding to master-cylinder and caliper disassembly, inspection, and assembly, supported by the Hydraulic Brake Drawing. Chassis sections also address wheel bearings, front shock absorbers, adjustable rear cushions, and steering stem ball races.

Frame cover and exhaust muffler removal are documented. Cable & Harness Routing drawings help avoid trapped wiring and misplaced control cables during reassembly.

The front-wheel installation notes warn that a misaligned speedometer drive can deform its retaining pawls when the axle is tightened. Follow the manual’s support and brake-contamination precautions during chassis work.

Ignition, Charging, and Electrical Fault Tracing

Troubleshooting flowcharts address hard starting, low power, poor running, charging faults, and loss of spark. Electrical test tables give component resistance, voltage, and continuity specifications; CDI and regulator/rectifier testing includes meter-specific guidance.

The wiring diagrams cover the 125cc model and the 150cc Singapore version. Ignition Circuit and Electrical Equipment Layout illustrations support fault tracing, while fuel-gauge, fuel-unit, lighting, and handlebar-switch tests extend coverage to instruments and controls.

The ignition section covers timing inspection and makes clear that CDI ignition timing is not adjustable.

Printable English PDF

The manual is supplied as one printable, English-language PDF with 185 pages across 17 chapters. This total includes two nearly blank chapter-end pages, numbered 6-6 and 8-9.
