2020 YZ250FX stalling issues.

2020FXMarc
MY previous bike was a stock 2015 YZ 250F that NEVER stalled riding it on slow rough trails.
My new 2020 YZ250FX is the opposite. It even stalls sometimes just putiing it in first gear.
Anyone have this issue?

Check your TPS setting and also your idle speed.

Did you get the new TSB reflash from Yamaha?

Thanks everyone. Turning up the idle helped, at the expense of a little popping on decel. I'm at 4000 feet. It only stalled once Today, putting it into first gear. Will certainly explore this reflash suggestion.

Use the power tuner app to see where your RPM is at. Then adjust it with the idle speed knob to between 1800 and 1900. That's what the book says. Also do a +1 in the FI part of your map to settle down the popping.
