bro crazytown.. do you know what is your CO setting?
Kev's O2 controller is aimed to cure the closed loop ECU reaction described below:
The closed loop is implemented for emission control. It comes into effect after a coolant temp of 60 degrees C, and when the ECU sees a constant throttle opening of below 20% between 2000rpm & 6000rpm, This circuit creates an A/F ratio of approx 14.7:1
Obviously I am a noob with these terms, but my commute yesterday told me that it did what it was supposed to do.
Previously when riding at low speed (around the car park), my hands would be covering the clutch & very careful with the throttle constantly, as the bike would "jump" at times.
When cruising at high speed, sometimes I felt as if I had a bad chain/wrong chain tension/flat spot on the tires... and the irregular jerky motions caused the sensitive throttle to move just a hair up or now... and the bike would be like limping forward.... when I was in a higher gear & lower RPM, it would be quite uncomfortable and would make me downshift..
With the controller on, I can literally lug the bike in 1st gear up and around the multi-storey car park.. and when cruising, even when the road surface is uneven, I don't feel the surging sensation... and I don't even feel it when I was actually at a higher gear than before when travelling at low RPM
It can be a very minute feel for some, but to sum it up, Kev's O2 controller made the bike less tiring to ride, for myself at least
