What to know before you order
The Xciting 400i uses a cartridge oil filter plus a strainer screen: the filter goes with every oil change at 5,000 km, and the screen is cleaned at 5,000 km and replaced at 10,000 km. Its battery is the larger YTX14-BS (12 V 12 Ah), and the drive belt is a 20,000 km replacement. Coolant lasts to 35,000 km, but brake fluid is due every 10,000 km.

Torque for the parts you replace
Clean, dry threads unless the row says otherwise. Aluminium cases strip long before a steel bolt complains, so use a torque wrench on the drain bolt and the plug.
| Fastener | N·m | ft-lb |
|---|---|---|
| Spark plug | 15-20 | 11-14 |
| Engine oil drain bolt | 20-29 | 14-22 |
| Oil strainer cap bolt | 9.8 | 7.2 |
| Final drive check and drain bolts | 7.8-12 | 5.8-8.7 |
| Drive face nut | 78-85 | 57-63 |

Electrical test values
Measured at about 20 °C with the connector unplugged. A reading far outside the range points at the part; a reading inside it sends you back to the wiring and the connectors.
| Part | Test value | Genuine part number |
|---|---|---|
| Ignition coil | primary 3.57-4.83 Ω; secondary 15-19 kΩ with the plug cap, 10.42-14.49 kΩ without | |
| Crank position sensor | 100-130 Ω | |
| Stator | between the yellow wires, 0.1-0.7 Ω |

Which model year do I have?
The year decides which number is yours where a row lists more than one. Decode your VIN with the VIN lookup, or read the model code on the frame plate, then open that year's diagrams from the model list.
