Using temperature, altitude, humidity, atmospheric pressure and oil-mix ratio, the app will show you a recommendation about jetting to your specific bike, so it can be useful to get a spot-on configuration and adapt it to the weather changes.<br><br>In order to get the weather values, the application can use the GPS 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 and internet connection, in this case, the user has to give the altitude and weather data.<br><br>The application is made up of four tabs that are described next:<br>- Results: in this tab, the recommended main jet, needle type and clip position, pilot jet and air screw position are shown. These data are calculated depending on the weather conditions and the engine configuration introduced in the next tabs.

I tried this setup and it worked great! Some may say that it doesn't work because the bike won't idle, but they don't understand that this is how bikes are race tuned - it is to help the bike slow down faster with engine braking. If you have a doubt, adjust it first and grab the throttle halfway - it will lift the front end well before it hits the powerband. I went to sand mountain (Utah - 700 ft high dune) and the bike was still grabbing more power as I was flying up the dune in 3rd gear 1/2 to wide open throttle. Highly recommended.

This app is still suggesting the 2006 and older needle jet N3EJ as standard for just about all temps/ elevations for a newer YZ250 including warm climate close to sea level. Yamaha changed to the N3EW needle in 2007 as it improved bottom and mid range. I assumed I needed to go with the leaner N3EJ needle as per this apps suggestion so I purchased one. It is not an improvement. I did plug in 2017 as the year of my bike. Take some time and get everything correct and current for one of the most common 2 strokes available. The other settings seem accurate. Also not a huge deal but a nice touch would be to list the YZ250X as a selectable option. I get that the jetting is the same as a YZ250 but at least list it.

First 2 stroke bike for son. Didn’t know a thing about jetting...short version. Played with jetting until I got ‘ole blue’ rippin. Found the app and adjusted the fine tune to match my jetting config. App is my “go to” for weather changes. Been swapping out jets per the app and all needed is a bit of air screw adjustment. Keeps up with the 2019 YZ250 and 2019 KX250 we have. 1998 YZ250 (stock displacement) Boyesen V3 reed valve FMF Fatty Running 93 pump gas with quality oil Thumpers rule !!!

Great app to dial in mine and my kids bikes as they are different sizes. Also riding year round and at different altitudes makes rejetting a breeze. Bikes run great and are responsive like they should be and I expect.

Love the app, but would like to see big bore kit jetting on the app. Hope it's a update soon.
