2004 Daelim S2-250 Service Manual (P/N C4077-90960)

• Official Daelim factory publication (Part No. C4077-90960) detailing the engine, chassis, and electrical parameters for the S2-series scooter build.
• Contains 43 exploded-view diagrams and 28 torque specification tables across 201 pages of unedited OEM data.
• Functions as a primary reference point to streamline workshop diagnostic and repair planning.

System Coverage and Workshop Utilization

The documentation outlines the component architecture for the underbone frame chassis and the 249cc water-cooled SOHC engine. It maps out the structural layout for the transmission, lubrication, fuel injection, and cooling assemblies. Mechanics will find exact diagnostic parameters for the CVT and variator systems, which helps reduce unnecessary bench time. Furthermore, the text maps the 12V 10AH electrical architecture through complete wiring diagrams, clearly indicating relay and fuse locations to trace electrical faults efficiently.

Specification and Reference Data

For precision work, the manual lists essential engine and frame fastener torque values. Key baseline figures include an intake valve clearance of 0.1 mm and a cylinder compression pressure of 15 kgf/cm² at 600 rpm. The total cooling system capacity is documented at 1.4 liters. Reviewing these factory specifications prior to a major repair ensures accurate parts staging and correct tooling setup. Please be aware that the mechanical values provided here serve strictly as a preliminary reference. Always consult the full factory documentation and adhere strictly to standard shop safety protocols before executing any physical maintenance tasks.
