Thought this might be interesting to you guys, Ive been doing a lot of reading about the stock 02 sensor and what to do with it when changing exhaust ect. I decided to ask the guys at dynojet and see what they recomend. I told them the year of the bike, and the modifications i made , ect. This is what they told me

Greetings gary, thank you for your inquiry. We appreciate your interest and support for our products.

For the modern bikes with closed loop systems we have found in recent testing and analysis that most modern engines now have actually been designed to run at the leaner factory settings. In the closed loop area of the fuel curve we find they generally run better if the factory closed loop system is retained and not changed. That area is generally very low engine load conditions at the low rpm and throttle, so it does not require substantial fuel changes to run optimally like the high rpm, high throttle settings do. Due to this and ever tighter emissions regulations at the state and federal levels we now recommend the factory closed loop O2 sensor components be left connected, and if using our Auto Tune it would only make adjustments outside that area where they are truly needed for the high engine load conditions at higher rpm and throttle settings. Leaving the factory sensors in place and installing the Auto tune for fuel adjustments outside the closed loop area actually gives you the best overall compromise between fuel economy and power and performance when actually needed. You get maximum economy in the low rpm throttle range, and max power and performance in the high rpm, throttle range.
