2018 KLX FI 250 no idle

Need a little help here, de smogged de restricted bike. Starts up beautiful with @ 1.500 rpm but once you start riding with bike fully warmed it either dies or has hanging idle at 3,000 rpm. I’m at wits end.

Sounds to me like a vacuum leak or possibly the O2 sensor. Did you disconnect it? The smog vapor recovery system has a lot of hoses. Might a disconnected one be still open letting air in?
