o2 sensor position

[Maj]

My race bike is not positioned much different, usually killed with lead before the heat gets it, make sure your sensor isn't at the bottom of the pipe or condensation can cause probs, and if your worried about heat you can put a spacer adaptor in to get it out of the airstream a little, still reads the same in this cooler position.
Backwash on a short pipe makes them innacurate, hang a rag over the end if you want short duration idle or part throttle readings but don't leave it there long....
