Jetting for Honda CR 2T 1.4

This application serves as a valuable tool for configuring the carburetor of Honda CR two-stroke motorcycles, specifically models CR 80, CR 85, CR 125, CR 250, and CR 500, enhancing their overall performance. By taking into account various environmental factors such as temperature, altitude, humidity, atmospheric pressure, and oil-mix ratio, the app provides tailored jetting recommendations to achieve optimal configuration and adjust for prevailing weather changes.

To acquire weather data, the application can utilize GPS for position and altitude information, while also leveraging a network connection to access real-time data from nearby weather stations. However, it is important to note that the application can operate without GPS and internet connectivity; in such cases, users must manually input altitude and weather data.

The application is organized into four distinct tabs:

• Results: This tab displays recommended settings including the main jet, needle type and clip position, pilot jet, and air screw position. These recommendations are dynamically calculated based on the entered weather conditions and engine specifications. Additionally, users can make fine-tuning adjustments for specific engine characteristics.
• Weather: Users can input current values for temperature, altitude, pressure, and humidity. Data can be entered manually or automatically populated by retrieving information from the nearest weather station via the GPS functionality.
• Engine: In this section, users are required to provide details regarding their engine model year, model designation, carburetor type, and the current oil mix ratio in use.
• GPS: This tab facilitates access to GPS data for current position and altitude while also connecting to external services to retrieve localized weather information (temperature, pressure, and humidity).

The application supports multiple measurement units: meters and feet for altitude; Celsius and Fahrenheit for temperature; hPa, mb, inHg, and mmHg for pressure.

It is compatible with the following models and years:

• CR80 from 1986 to 2002
• CR85 from 2002 to 2007
• CR125 from 1986 to 2007
• CR250 from 1986 to 2007
• CR500 from 1986 to 2001
