Engine Fluids, Gear Oil & Filter Specifications
| Engine Oil Viscosity & Standard | SAE 15W-40 / 10W-40 API SL/SJ JASO MA/MA2 (Wet Clutch) |
|---|---|
| Engine Oil Capacity | 0.9 L (without filter) / 1.0 L (with filter) |
| Final Drive / Gearbox Oil | Uses engine oil (Shared crankcase wet clutch manual transmission) |
| OEM Oil Filter Part Number | C4472012 (Paper cartridge filter) |
| OEM Air Filter Element Part Number | C4722000 |
| Spark Plug Model & Electrode Gap | NGK CR8EH-9 (0.8 mm) |
Field note: The Stella 4-Stroke engine holds 0.9L for routine drains and 1.0L when renewing the C4472012 paper cartridge filter. Because the engine oil lubricates the wet clutch and 4-speed manual gearbox, ALWAYS use JASO MA/MA2 certified oil. Never use JASO MB or friction-modified passenger car oils which cause wet clutch slippage.
Ignition & Electrical System
| Component | CDI Control Unit |
|---|---|
| OEM Part Number | SF324-0322 |
| Fitment | Genuine Stella 4-Stroke |
| Dimensions/Notes | 8-pin configuration |
| Torque Spec | N/A (rubber-isolated mounting) |
| Fluid/Electrical Notes | Integrates with LML Star 200 4T harness |
| Cross-Compatibility | LML Star 200 4T |
Field note: Because there is no torque spec for the CDI itself, mechanics often over-tighten the mounting bracket screws to fight vibration, which cracks the module's potted resin housing and produces intermittent ignition cutout at high RPM — a fault that is nearly impossible to diagnose without a spare unit to swap in. Mount with light, finger-tight pressure only and let the rubber isolation grommets absorb vibration; never force a rigid mount against the frame.
