Jetting CR125 Shifter Kart 1.5

This application offers a jetting recommendation for Stock Moto / Mod Moto shifter karts equipped with Honda CR125 engines and Keihin PWK 38 or PWM 38 carbs based on current weather conditions and specific engine configurations.

To determine weather values, the app utilizes location services (GPS or WiFi) to acquire position and altitude data, alongside network connectivity for temperature, pressure, and humidity information from the nearest weather station. The application is still operational without GPS, WiFi, or an internet connection; in this scenario, users must input the weather data manually.

The application comprises four tabs detailed as follows:

• Results: This tab displays the recommended jetting settings calculated considering weather conditions, engine specifications, and track setup detailed in subsequent tabs. The provided jetting setup includes main jet, needle type, clip position, and pilot jet values. An accurate main jet value with decimals is presented along with air density and density altitude information. Users can fine-tune the main, needle, and pilot circuits for customized jetting adjustments to suit individual engine requirements. These personalized values will be saved for future sessions.
• Weather: Users can input the current temperature, pressure, altitude, and humidity values manually on this tab. Alternatively, the app can retrieve this data from the nearest weather station automatically (via the GPS tab).
• Engine: This section allows users to input engine specifics including class (Stock Moto or Mod Moto), air filter type (clamp-on air filter, airbox with or without filter), fuel feed system (pump-around or non-pump-around), oil mix ratio, and circuit type (spring or road racing, short or long). The jetting setup will be adjusted based on the track type specified.
• GPS: This tab enables users to utilize location services (GPS or WiFi) for real-time position and altitude data retrieval. Additionally, it facilitates connectivity to an external service for accessing weather conditions from the nearest weather station (temperature, pressure, and humidity).

The app supports various measurement units: ºC and ºF for temperatures, meters and feet for altitude, and mb, hPa, mmHg, inHg, and atm for pressures.
