I unplugged the O2 sensor and bike idling turned excellent instantly...



I switched it off and self started it again it took longer self and half open throttle to start and struggled to start with O2 unplugged...


I switched it off again and then again started it again needed at least half throttle opened and longer self to start... but super smooth idling


now this time I plugged back the O2 sensor and started it again this time it did not struggle and instantly started without any throttle assistance but the idling went bad again...



I already cleaned the O2 sensor and dipped it in kerosene petrol mixture over night but seems like that did not helped much...


I think this indicates that fault is really in the o2 sensor? right?
