Jetting for GasGas 2T Moto 2.3

2003-2023 Models

This application utilizes temperature, altitude, humidity, atmospheric pressure, and your engine configuration to calculate the optimal jetting (carburetor configuration) and spark plug to use for GasGas 2-stroke Enduro and Motocross motorcycles.

The app can automatically retrieve the position and altitude to obtain temperature, pressure, and humidity data from the nearest weather station via the internet. Supported devices use an internal barometer for enhanced precision. For increased accuracy, a portable weather station can be utilized. The app is functional without GPS, WiFi, and internet; in such cases, users need to input weather data manually.

• Various values are provided for each carburetor configuration: main jet, needle type, needle position, pilot jet, air screw position, throttle valve size, and spark plug.
• Fine-tuning options are available for all these values.
• Keep a history of all your carburetor configurations.
• Graphical representation of fuel mix quality (Air/Flow Ratio or Lambda).
• Selectable fuel types including gasoline with or without ethanol, as well as racing fuels like VP C12, VP 110, VP MRX02.
• Adjustable fuel/oil ratio and a mix wizard for the perfect ratio calculation (fuel calculator).
• Carburetor ice warning feature.
• Option to use automatic weather data or a portable weather station.
• If location sharing is declined, manual selection of any place globally adapts the carburetor setups accordingly.
• Ability to choose different units of measurement: °C and °F for temperatures, meters and feet for altitude, liters, milliliters, gallons, and ounces for fuel quantities, and millibars, hectopascals, millimeters of mercury, inches of mercury, and atmospheres for pressures.

Valid for the following 2T models from 2003 to 2023:

• MC 50
• MC 65
• MC 85
• MC 125
• ...

The application comprises four tabs described as follows:

• Results: Displays main jet, needle type, needle position, pilot jet, air screw position, throttle valve size, and spark plug details calculated based on weather conditions and engine specifications. Offers fine-tuning adjustments for precise engine adaptation. Additional information includes air density, density altitude, relative air density, SAE - dyno correction factor, station pressure, SAE-relative horsepower, volumetric oxygen content, and oxygen pressure. Graphical representation of air-to-fuel ratio (lambda) is also available.
• History: Shows the history of all carburetor configurations. Any modifications to weather conditions or engine setups will be saved in the history. This tab also stores your favorite settings.
• Engine: Configure engine details such as model, year of manufacture, spark plug manufacturer information, fuel type used, and oil mix ratio.
• Weather: Allows setting current temperature, pressure, altitude, and humidity values. Utilize GPS for automatic position detection and connect to preferred external weather data sources. The app supports pressure sensors built into the device if available. Manual selection of any location globally is also possible with automatic adaptation of carburetor settings.
