My Check Engine Light has come on after I installed a Servo Buddy since I installed a Yoshimura Alpha T Slip On Exhaust. The code is “Exhaust Motor Fault”. I’ve cleared the code with a OBD Scanner but it comes back.

My bike is a 2021 CBR1000RR ECU Flashed using BrenTuning handheld. the Servo Buddy was sold for 17-22 cbr1000rr bikes and I got a replacement to see if the previous one was defective but it didn’t fix the check engine light issue.

Also, I’ve noticed my bike is more jumpy/sluggish when taking off in 1st gear…

need any advice/help! Beyond disappointed and frustrated. :/
