I have gone through the last 3 years of posts and know that the subject of fuel controllers has been beat to death, but I haven’t been able to find an answer to my specific questions. Also, before anyone mentions it, I know about the Hard Racing wide band controller and have watched their video. However, that video is from 2015 and I’m not sure if that info being that old is still relevant. Also, I already have a standard AT-200 and I’m not really interested in replacing it. What do I need to do with the Stock O2 sensor? Do I leave it plugged in and zip tie it to the frame, or do I need to buy another part to put in its place? I have already began the install but have not completed it and put the bike back together. Also, this bike is just going to be a daily rider not a race bike, do I really need to worry about closed loop fuel control? As far as mods, I have the PCV with At-200, cat/muffler delete mid pipe, off brand slip on pipe (for now) and k&n air filter with open air box lid. I run premium pump fuel, usually 93 Octane in my area. My biggest concern is just not melting my top end by running it too lean. Am I alright with this setup or am I missing something major? Thanks in advance!
