Desperate for help/advice.
I am a victim of the gixxer herky jerky problem. O2 sensor has been replaced twice under warranty it keeps going. after so little miles. I have got M4 slip on with cat still there along set valve and O2 sensor.
Im considering keeping the cat on along set valve but get rid of the O2 sensor with PCV. is this a good move? sorry i am a noob, educate me.
