Just code the code for "Oxygen sensor always too lean"

Does anyone remember the part number? I remember seeing the Bosch part number just didn't right it down.
Thanks.

Thanks Wilson. I did try the search for the "oxygen sensor" but it came back empty.
Besides, the Search only goes back up to 8 days. Did I do something wrong?
Anyway, thanks for the quick response. On my way to get one.
BtW, are there any tricks in doing the replacement?

click "Search," not Google Badweb, is that what you are doing?

I clicked Search, highlighted the Old School forum, typed "X1 Sensor" and boom.

Kalali, do you have the special socket to get the o2 sensor out. If not, get a boxed end wrench that fits the sensor, one with an off set head is ideal, then cut it off about 5 or 6 inches from the end. When you do that, you dont have to take the battery out, but it is alot easier if you do take the battery out. Hope that helps, Matt Tully

Thanks guys. What a piece of cake...
Ended up getting the socket. No big deal.
Strangely enough, my off-idle throttle response also improved greatly. I am thinking since I had the "closed loop at idle" enabled, and the O2 sensor was not working properly, the transition from closed loop to open loop when you crack the throttle was a bit slow. Not sure if this theory is correct but it sort of makes sense. Thanks God we have the ECMSPY...What an awesome tool. The bike runs perfect now. Oh by the way, there was a light layer of soot on the O2 sensor. Is that normal? The bike has about 15K miles.
Thanks again for all your quick replies.

Kalali, in your first post here, did you say you got the code for o2 sensor always to lean, did you get that off the ecmspy? I am going to use the ecmspy for the first time today, I guess I will try to do a TPS reset. Should I check for trouble codes as well you think.

My first clue was when I checked the AFV last night using the ECMSPY. It went up from 100 to 117. Then I took the bike for a ride this morning and the engine light came on a soon as I rode for five minutes. Hooked up to the ECMSPY, checked for trouble codes and bingo O2 sensor.
Use it regularly. Do a TPS and AFV=100 reset while you have it up. Also check the AFV regularly. Any fluctuation in AFV tells you whether you are running rich or lean. Bad seals, exhaust leak, cracked header, etc., all will show up as low AFV (<100) pointing to a lean mixture.
Yes, I got 12014.

"Any fluctuation in AFV tells you whether you are running rich or lean. Bad seals, exhaust leak, cracked header, etc., all will show up as low AFV (<100) pointing to a lean mixture."

I think you may be mistaken. The AFV will try to correct a lean mixture by increasing the number above 100% Mine runs about 120% due to a White Bros. E-series with all the packing blown out and 13 discs as well as a K&N Air filter.

I need to do some tuning to correct it after I re-pack the muffler but it's always run very well.

Steve, you are actually confirming what I said. Your AFV=120 is telling you that your maps are too lean and the ECM is adding about 20% more fuel to your maps in order to compensate for your exhaust (assuming every thing else is OK). If you switched to a Race ECM (which is much richer over the entire map), you will be ale to maintain a an AFV=100% more closely.
Try increasing your fuel maps in small % increments and watch your AFV.

If your REAR HEADER GASKET is "BAD" it will make the O2 sensor think it is bad !!!

Replace the gasket with GASKET,exhaust port PN 17048-98 !!!
