Very interesting. I put a full new system on my bike but it doesn't have an O2 sensor in the headers. I was fine tuning a few bits & bobs & talking to my mechanic mate in his workshop just a few weeks ago & he said if I want it to run right throughout the rpm range then I should fit an O2 sensor. I was planning to do it next week. Now I have even more reason to do so!
