To provide a more accurate response, I need to know the specific type of motorcycle you are referring to, as different motorcycles may have variations in their starting procedures.
The choke is typically used on motorcycles with carbureted engines to assist in starting the engine when it's cold. It helps enrich the air-fuel mixture by restricting airflow, allowing for easier combustion in colder conditions.
Here's a general guideline for using the choke on a motorcycle:
- Before starting the engine, ensure that the fuel petcock (fuel valve) is turned on.
- If the engine is cold (hasn't been running for a while), locate the choke lever or knob. It is usually positioned near the handlebars or on the carburetor itself.
- Move the choke lever or knob to the "ON" or "FULL" position. This setting restricts the airflow, enriching the fuel mixture.
- With the choke in the "ON" position, start the motorcycle as per the manufacturer's instructions. This usually involves turning the ignition switch, using the kickstarter, or pressing the electric starter button.
- Once the motorcycle has started, allow it to warm up for a short period (typically a few minutes) with the choke still in the "ON" position. The exact warm-up time can vary depending on the motorcycle model and ambient temperature.
- As the engine warms up, you may gradually move the choke lever or knob back towards the "OFF" or "NORMAL" position. This increases the airflow, gradually leaning out the fuel mixture.
- Once the engine is running smoothly and warmed up sufficiently, you can fully disengage the choke by moving the lever or knob to the "OFF" or "NORMAL" position. At this point, the engine should be able to operate without the assistance of the choke.
Remember, these steps are general guidelines, and it's important to consult the motorcycle's owner manual for specific instructions as starting procedures may vary among different motorcycle models.
