I had the 2019 XT250. It started instantly no matter how long it sat. But it did have a little of that on/off throttle action...mostly in 1st, 2nd was better and that's where I tried to do most of my technical riding. Anyway guy I sold it to is very happy with it

And I'm 2 bikes down the road

I think 95% of the bikes are FI now, in the Commie state of CA I bet you can't buy a carbureted bike ...IDK but seems to be going that way.
I just bought a new ECU for the Husky so I can mitigate some of the dreadful OEM tuning.
