To fix a steering lock issue on a KEEWAY Versilia 2025 with part number ARN125, check the ignition switch system. Follow these steps:

1. Use a multimeter to inspect the resistance between the blue/white and green/white leads at 20 °C. The resistance should be between 100 and 180 Ω.
2. Check the continuity between the black/white lead and the black lead end.
3. If resistance is outside the specified range or there's no continuity, replace the touching off coil (part of the ignition switch).
4. Test the switch function using a 1.5V LED between blue/white and green/white leads:
- In "OFF" and "LOCK" positions, the circuit should be connected.
- In "ON" position, the circuit should be disconnected.
5. If the LED does not behave as described, replace the ignition switch.

These steps help ensure the steering lock mechanism tied to the ignition switch functions properly.

In this process, fuel is filtrated three times (first of all fuel is filtrated when it passes through netty nylon tupe before going into fuel filter, secondly fuel goes through the cavity of fuel filter, finally fuel is filtrated when it passes through the filter installed between inlet oil switch and carburetor).

  • Page 44: Idle Speed

    Carburetor working principle 1. Inlet oil road Fuel flows into floater chamber of carburetor for its own weight, which communicates with atmosphere for balance tube of carburetor that guarantees pressure in floater chamber is the same as atmosphereic pressure. Floater goes up along with oil level, when oil level raise certain high, the floater drives needle valve to shut off inlet oil path.，...
