I agree with above, like i said earlier o2 carn't do much to adjust system by itself.
On a system without an o2 sensor your ecu does what it's programmed to do by preset data that's it.
On a system with an o2 sensor ecu is still working within those same pre programmed parameter's it's just that there is extra one's to allow it to give/trim some fuel in open loop if it see's it's not at optimum air/fuel ratio.
As for there being too many input sensors on fuel injection just remember it's adjusting every second for conditions so it kinda needs a bit of info to help![Very Happy Very Happy](https://www.australian-hayabusa-club.com/MyBB/images/smilies/icon_biggrin.gif)
And Cam, biggest question you should ask yourself is this, what do you want to do with the bike (i.e daily ride etc) and what do you expect from it, i.e drivabillity/economy/out right power. From there plenty of people around here from what i see to point you in right dirrection.
