"title": "Works great",
"body": "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.",

"rating": 2,
"title": "Update Your App",
"body": "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.",
