It goes to the white map. The green map always stays the same.

That's what worried me. Keep us posted

I have it on my ‘23 350 SX-F. The dealer had to update the ECU to get it to pair. It was definitely worth the money. I’ve created a couple of maps playing around with things like traction control and engine braking and it definitely makes a difference. I also paid for the Rider subscription. The data logging is really cool, but for some reason I can’t get it to read jump distance or height.

This is crazy... I rode both my YZ250, then my MC350F back to back on Thursday at a track I built a month ago for some friends. Both bikes are set up pretty well at this point. I was two seconds faster on the 250 than I was on the 350 according to my Garmin GPS watch and a private Strava segment I have for that location... I didn't jump the three in the two-three section on the YZ250 and it was still faster on my two best laps than on the two best laps of the 350F. I assume...

Thanks for the reply. PC just said some peoples go in the whole way to the tab, and others don’t. Said it’s fine to run… but seems odd to me. Guess if you haven’t had an issue, it’s ok? I haven’t started it with it yet, but will look it over closer for leaks over the weekend.

A YZ250 would be a great second bike if you like a 250 two stroke. The 2022 KTM two strokes with some jetting work are superior to the new injected models. After riding the 2023 TC125 and TC250, you can pry my carburetors from my cold, dead hands. I haven't ridden an aftermarket ECU on the newer Austrian two strokes, Maybe that would change my opinion?

I currently own both. I've been on various YZ250s since 2007 and have had a couple YZ125s since about 2012. I love the 250 two stroke, but it's a lot of work to remain competitive on it as the 450F has improved with each generation. The 350F makes a lot more power than a mildly modified 250 two stroke. The 350F is also far easier to ride in any situation than the YZ250. It's the broad, smooth power delivery of the four stroke without the heavy feel of the 450F. The 350F feels as light on the track as the...

For some guys, that's probably the sweet spot. I think guys who see it mostly from the chassis & handling angle still feel advantages in a 350F. It seems like I heard Keefer and one of his buddies talking about down-tuning a 450F and how it still doesn't feel the same. Suspension settings have to be stiffer on a 450F to deal with the increased torque. In some places on the track that adds to the factors making the 450F feel a bit heavier. I really think a guy has to ride the bikes back to back to know what...
