I've got a call in to Dobeck; I got my Iceage nitrous kit and the instructions for the AFR sensor say to install 4-8" from the head--well, all you KTM guys probably know that's the part making the extreme bend in front of the frame, which is less than ideal. My last install was on the YZ, which given the backwards design was a non-issue. I know there's a lot of KTM/Husky kits out there, and that Rush is successfully running N2O, so what's the scoop? How far back did you place it? Seems like it would be an issue with any conventional engine and that farther back on the straight run must work ok.
