2009–2013 Daelim Roadwin 250R FI Service Manual (P/N 11200-RFZ-0000)

This 288-page PDF contains the Daelim Roadwin 250R FI Service Manual, dated October 2009. Its internal engine repair procedures and electrical tests are suited to experienced mechanics equipped for precision measurement and scan-tool diagnosis.

The cover identifies the 250R FI, but the introduction names VJF125 and the general specifications list a 124.1 cc engine. These conflicting model references require an applicability check before purchase.

• Engine removal and top-end repair, including cylinder-head disassembly, valve-guide replacement, valve-seat refacing, and cam-chain timing.
• Wet multiplate clutch inspection and reassembly, transmission teardown, shift-fork checks, crankshaft inspection, and balancer-gear alignment.
• EMS diagnostics cover fault-code retrieval and clearing, ECU initialization, idle speed actuator (ISA) PWM adjustment, and scan-tool checks of ignition timing and engine speed.
• Cooling-system procedures address radiator-cap pressure testing, thermostat and fan-switch checks, and water-pump mechanical-seal replacement.
• Hydraulic brake service includes front and rear master-cylinder and caliper overhaul, pad replacement, disc inspection, and air bleeding.
• Front-fork disassembly, seal and bushing replacement, steering-stem bearing service, and swingarm pivot inspection support chassis repairs.
• Ignition and charging-system tests accompany starter-motor disassembly, brush and armature inspection, and starter magnetic-switch diagnosis.

Engine Repair and Service Data

The manual organizes mechanical and electrical data into 22 primary sections. The opening chapters cover maintenance schedules, fastener torque values, and model identification markers located on the frame and engine crankcase. Routine service procedures include compression testing, valve-clearance inspection with shim selection, spark-plug inspection, and drive-chain adjustment.

Engine inspection data goes beyond general specifications. Cylinder and piston procedures address bore wear, ring-groove clearance, piston-pin fit, and connecting-rod small-end clearance. Oil-pump service includes rotor-clearance checks, while the crankshaft chapter covers runout and connecting-rod bearing clearance.

The service information distinguishes clutch and gearshift-spindle work that can be performed with the engine installed from transmission and crankshaft repairs requiring engine removal and crankcase separation. Component-specific torque tables, fluid capacities, wear limits, and electrical test specifications accompany the relevant procedures.

EFI Diagnosis and Wiring References

The Engine Management System chapter covers the combined manifold-pressure and intake-temperature sensor (MAPAT), throttle position sensor (TPS), and engine temperature sensor (ETS). Oxygen-sensor heater and lambda-signal faults have separate diagnostic procedures.

Fuel-system repair coverage extends to throttle-body disassembly, injector circuit testing, and fuel-pump pressure and delivery checks. The EMS material also distinguishes the injection-system flywheel and stator from carbureted components.

Diagnostic instructions explain the difference between prioritized malfunction indicator lamp (MIL) blink codes and scan-tool access to all stored faults. ECU terminal functions and a terminal-specific error checklist support checks for open circuits, shorts, and poor connector contact.

The electrical references include the ECU wiring diagram, charging diagram, and starting diagram. A complete motorcycle wiring schematic shows connector pin locations and connections between the ECU, sensors, actuators, relays, and instruments.

Wheels, Suspension, and Repair Limits

Wheel-service chapters cover axle and rim runout checks, hub-bearing replacement, and rear-wheel drive-damper inspection. Steering procedures include bearing-race replacement and adjustment.

Rear suspension coverage includes shock removal, inspection, and lower-mount bushing replacement. The rear gas damper is treated as a replacement assembly, with a separate disposal procedure rather than an internal overhaul procedure.

Exploded transmission and front-fork assembly views show the arrangement of gears, washers, bushings, and seals. Bodywork removal instructions cover the seats, cowls, fenders, and exhaust components needed for service access.

Workshop Tools and Assembly Cautions

Tool references identify the clutch center holder, ACG rotor puller, valve-guide reamer, and fork-seal driver. Electrical checks call for a digital tester, peak-voltage adapter, and diagnostic scanner.

Flywheel installation notes explain how contamination at the crankshaft taper can damage the Woodruff key. Starter-motor assembly cautions identify the risk of winding damage if magnetic pull draws the armature against the case.

Always rely on the complete OEM documentation and standard shop safety protocols before performing repairs involving pressurized fuel, hot coolant, or hydraulic brakes.
