Jetting KZ Kart

Jetting app for TM kart engines


Jetting TM Kart is an application which provides, for the current weather conditions and a given engine configuration (engine model, floats, etc.), four jetting recommendations for TM K9, K9B, K9C, KZ10 and KZ10B engines that have DellOrto VHSHS30 carbs.

In order to get the weather values, the application can use the location service (GPS or WiFi) to obtain the position and altitude, and the network connection to get the temperature, pressure and humidity from the nearest weather station. Nevertheless, the application can run without GPS, WiFi and internet connection, in this case, the user has to give the weather data.

The application is made up of four tabs that are described next:

  • Results: in this tab, four different jetting setups are shown. These data are calculated depending on the weather conditions and the engine and track configuration given in the next tabs. For each jetting setup, the following values are given: main jet, emulsion tube, needle type and clip position, inner pilot jet (iddle diffuser) and outer pilot jet (iddle jet). Under the recommended main jet, the calculated real value with decimals is shown.In addition, this tab lets do a fine tunning adjustment for the main (high), needle (mid) and pilot (low) circuits for each jetting setup to adapt to the concrete engine. We strongly advise you to test each jetting setup and adjust these values (if necessary) to get an optimum performance. These values will be stored and used in the future sessions.
  • Weather: you can set the values for current temperature, pressure, altitude and humidity. The values of this screen can be manually set or can be loaded by the application reading the data from the nearest weather station (from the GPS tab).
  • Engine: you can configure in this screen the information about the engine, that is, the engine model (K9, K9B, K9C, KZ10, KZ10B), the float type and height, the oil mix ratio and the type of the circuit (spring or road racing, short or long). Depending of the track type, the jetting setups will be adapted.
  • GPS: This tab allows to use the location service (using GPS or WiFi) to get the current position and altitude, and connect to an external service to get the weather conditions of the nearest weather station (temperature, pressure and humidity).

The app let you use different measure units: ºC y ºF for temperatures, meter and feet for altitude, and mb, hPa, mmHg, inHg y atm for pressures.
