Ok setting suggestions
But the pilot jet recommendations are far off, ie 5000 to 10,000 asl only recommends a turn out on a/s when I’ve found 2 sizes down on pilot is necessary, seems to recommend rich settings here. It’s difficult to input elevation with the keyboard being in the way.
Response from developer
Hello, the issue with the elevation input is solved since last update. In the case of the pilot jet recommendation, our model tries to enrich at low in order to be safe (most seizes are after WOT and suddenly close throttle), and that let us put a one size leaner main jet to maximize power.
Please issue refund.
This app is glitchy. It won’t let me input elevation and doesn’t have all the info for my bike.
Response from developer
Please send us an email to mobile@isenet.es. We've updated the app in order to solve this issue, but in the case it's not ok, we'll refund you. Best regards.
Spot on…!!!
I use this app for all my two strokes. I live in Reno Nevada and ride Nor Cal MX tracks often. The jetting recommendations is always spot on for me.
More riding and less jet changes. 😎

Need updates!!!
Come on man we’re riding 2023 bikes and this app is still back at 2021 please up out an update already
1998 jetting
After playing around with the fine tuning I can re-jet with local weather data and the bike runs like a champ .
Great app
My bike runs very well with the setup given by this app. Oil mix ratio adjustment is fine too
Engine runs clean and fast
My YZ125 was too rich with stock jetting. After set up the carb with this app, the mileage has increased and the engine runs like a dream
Jetting info incorrect
Hi, like the idea of this app and want to use it, but the specs on the app are incorrect for the 2019 (2020 is the same as 2019) YZ85. In 2019 Yamaha redesigned the YZ85. Can you please update the app or refund my money?
Here are the correct stock specs, please verify though.
YAMAHA YZ85 JETTING FOR THE KEIHIN PWK 28mm
Here are MXA’s recommended jetting specs (when changed, stock specs are in parentheses):
Main: 145
Slow jet: 45
Needle: NBKF
Clip: 4th from top
Air screw: 1-1/2 turns

Nicht schlecht
Muss noch auf Herz und Nieren geprüft werden
Dialed In
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.
Not accurate
While the fantasy of it is nice when I jetted my yz250 to the apps recommendations it was so rich it barely ran.
Update Your App
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.

Leider nicht auf dem neusten stand. Wir fahren eine Yamaha yz 85 2019. Gruß Jörg

Hallo, im letzten Update haben wir die Modelle für 2019 hinzugefügt. Bitte aktualisieren Sie Ihre App, falls Sie dies noch nicht getan haben, und schreiben Sie uns an mobile@isenet.es, falls Sie Fehler oder Zweifel haben. Grüße
Works great
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.

Might work for your bike, not mine
Looks nice and recommended setting seem to align with other information I've seen online for tuning older YZ250s. But only covers up to 2015 model year and limited to 10,000 ft elevation, and doesn't cover YZ250X.
I ride a 2016 YZ250X, and often go over 11000 ft. The base settings the app comes up with don't match what my manual says, so I'm not comfortable using the app's recommendations for altitude adjustments.

Needing new features
Love the app, but would like to see big bore kit jetting on the app. Hope it's a update soon.
Yz jetting.
This app is helpful, I currently use the yz250 setup, but wish they would update with the YZ250X. This is why it's getting ***
Not useful
I don't like giving poor reviews, but this app was useless for me. It doesn't even seem to work properly.

Yz 250 jetting
Takes all the guess work out, fine tune capabilities. Well worth the $$
Most used app on my phone
Easiest way to make sure your jetting is perfect. Definitely worth the money.
