hanjob Posted January 25, 2016 Share Posted January 25, 2016 Hi guys, I just installed an Akrapovic exhaust yesterday and the OEM O2 sensor seems to be way too small for the O2 port on the new exhaust. I don't have any pics, but I was hoping somebody would have an answer for this if I'm missing something? Thanks in advance Link to comment Share on other sites More sharing options...
cndnmax Posted January 25, 2016 Share Posted January 25, 2016 There's an reducer adapter for it, not sure if that model comes with it or not. Take it as a sign to get a fuel controller, remove the O2 sensor, and throw a plug on the exhaust. Link to comment Share on other sites More sharing options...
yamobethere Posted January 25, 2016 Share Posted January 25, 2016 Is this the carbon or titanium? Link to comment Share on other sites More sharing options...
hanjob Posted January 25, 2016 Author Share Posted January 25, 2016 I'm thinking of saying screw it and get a plug for it, disconnect the OEM O2 and reflash the ECU with 2WDW. Exhaust is Akra Carbon. What do you guys think? Link to comment Share on other sites More sharing options...
Tyler Jane Posted January 25, 2016 Share Posted January 25, 2016 I got the Akrapovic Titanium and it came with an adapter for the O2 sensor. If you got it shipped from the distributor, it should be included. If you got it second-hand, you might need to go buy your own. Link to comment Share on other sites More sharing options...
pineappleunderthesea Posted January 25, 2016 Share Posted January 25, 2016 My Akra Carbon came with the reducer (bought it in December, so very recently). Check all your bags again, I also didn't see it at first and was cursing the world. Link to comment Share on other sites More sharing options...
gregjet Posted January 26, 2016 Share Posted January 26, 2016 I posted on this and it disappeared. The O2 sensor on the Yammy fitted straight into the existing threaded port. They were both large sensor sizes ( 18mm?) . I think US sensors must be the smaller size to other places. You could get the bigger one on ebay cheap ( makesure you get the right number of wires though) and fit it. AS FAR AS I KNOW the sensor electronic profile is the same only the thread is bigger. I am happy to be corrected on this though. Anyone tried one of these with success? http://www.ebay.com.au/itm/Oxygen-Sensor-O2-Eliminator-Yamaha-FZ6-FZ6R-FZ1-FZ8-FJR1300-MT01-MT09-FZ09-/370807613315 Go forth and modify my son...go forth and modify...

gregjet Posted January 26, 2016 Share Posted January 26, 2016 Isn't it going to screw up the fuelling in the closed loop part of the throttle just disconecting it. My BMW and the Husky got really upset about not having the sensor out of line. The PCV had a eliminator wire for the purpose when you fitted it. Go forth and modify my son...go forth and modify...

Premium Member wickedtwister Posted January 26, 2016 Premium Member Share Posted January 26, 2016 From what I understand about it from talking to nels at 2 wheel dyno works is its only sending a signal to computer on decel or when engine load is under 5%. So when the econ light is on the stock o2 is being read. If you have had a fueling controller or flash completed you should be good to go. Even stock I doubt you would see any huge degradation in fuel economy. It just going to richen up when the econ light is on. Link to comment Share on other sites More sharing options...
hanjob Posted January 26, 2016 Author Share Posted January 26, 2016 Sounds like I will be unplugging it and plugging the O2 port! Link to comment Share on other sites More sharing options...
James Bond Posted August 30, 2020 Share Posted August 30, 2020 What do I even search to find the adapter? I need it today from Home Depot or Lowe’s. Link to comment Share on other sites More sharing options...

Premium Member Evill_Ed Posted August 30, 2020 Premium Member Share Posted August 30, 2020 You need an M18 x M12 O2 sensor bushing. Try an Autozone or the like for one. If if you just need to plug the hole for now, a spark plug with an 18mm thread will fit it.
