has anyone bought a "universal" type O2 sensor for replacement duty on an 1125? i've gotten a code for that amongst several others. including AFV being outta whack. one for the IAC being outta place the VSS not doing it's job and the IAT too. now the IAT is my fault. I noted the front AFV was actually at 99% the rear was at 104% bike was getting horrid mileage and was way down on power. most of a big can of carb cleaner later the throttle bodies aer looking much better the valves are a little less gooked up and the idle seems to be smoother. test ride revealed that the ride quality was better but still way down on power and still has a miss under moderate to hard acceleration. i added some sea foam to the tank a little more carb cleaner. break out the laptop clear codes and lock AFV at 117 for the time being. so back to the question posed anybody use a universal O2 senor? if so do you still have the part number floating about? when i was getting the carb cleaner and seafoam advance has one for $18 and the pigtail looke about the right length for the front but i didn't have the OE one for comparo on the type of connector they had crimped on there already, with the universals i am used to seeing 2-4 crimp on connectors 2-4 plastic connector bodies and enough pigtail to trim down to match the one being replaced.... ideas thoughts assist? | ||

sounds like this site is working on something: http://www.nightrider.com/biketech/hd2007HD_wbo2_u pgrade.htm | ||

What ECM are you using? | ||

I would say there is a bigger problem then the 02 sensors. I had afv's of 120 100 and it still ran great. If u are concerned go into diagnostics mode and check the voltage of the 02 sensors, then swap them and see if the afvs change, if they do, its the 02 sensors, if they hold, its the something else. | ||

I would suggest swapping out your injectors, if it's a 08 bike i would upgrade to the later style ones from ebr. It cured my problem which seems very similar to yours. | ||

The IAT is the air temp sensor, so if it's reading high (or way off) then it will probably tell the ecm to trim fuel and make it run like crap.
Means nothing, it's a 5% difference between cylinders. I went to wideband sensors because I had originally planned on doing my own tuning. Erik Buell Racing did it for me, totally kicks butt with low to mid 140's hp, so I guess I kinda wasted some $$ on these, but still worth it anyway. I used PLX Devices, bought a pair of the controllers, sensors and a display unit/data logger. Works awesome, sends a NB output back to the original connection but allows me to see what it's really doing. It's not perfect, but it's pretty close. I guess the only thing I'd do different would be is to trim the wire harness that came with them, they were WAAAAAY too long, maybe 10' or so of wiring. It's all coiled up under the seat.      | ||

D i'd beg to differ that it "means nothing" as in my case the bike was running like complete shit. All of the above being said from all parties seems the original question is no. So far after reset no codes have been thrown in a littlee over 100miles of riding both super slab and stop n go in some warmer late day temps here in sunny fla. I locked them @ 117 and that seems 'ok' at the moment. Yes I am saving my pennies for Eriks ecm but I gotta tell ya it really burns me that I have to spend an extra 250 to get the bike to run "right" I know the responses and yeah that's all fine and good but really it's straight bull and we all know it. | ||

I'm just saying that 5% won't make it run like crap. 20%, possibly, but not likely. The stock ecm can handle up to a 25% spread before it throws a code. The root cause of it running like crap is something else. If you lock the fuel table at +15% over stock, it should run a bit better until you hit the high temp that the IAT skews the fuel too much to compensate for and then it will run crappy again. You need to know whats truly causing the problem. Throwing a race ecm at it won't fix it if you have a sensor on the fritz. Buy the ecm, but fix the other issues first. | ||

Also, spending the $250, sure it sucks even if its worth it. I spent almost $600 for the wideband stuff. Its just a very expensive a/f monitor right now. I'd still do it again though, just like I bought the ecm. Well worth the coin to have it. I probably would have paid even more than I did, knowing what I know now. | ||
| Boogiman1981 |
Yes you're right and I'm working on fixing it now thus. The original question regarding the Bosch universal fit O2 sensors. Looks like I'm gonna guenee pig it for the group. I will report back with what I find. | ||
| D_adams |
I have those sensors (LSU 4.2?) on mine. I think they run about $50 each, so they may not be what you were referring to. They are heated sensors if I recall correctly and probably wont work right as a strictly narrowband sensor. The controller is what sends out the narrowband signal, not the sensor itself and is optional. It (the controller) will send out both nb and wb signals. If you were talking about a specific nb sensor, just ignore me. I don't have any prior experience with them, the wideband ones are all I have messed with. | ||
| Boogiman1981 |
Sorry if I wasn't more clear yes I am referring to an O2 sensor that is $18 at advance discount auto parts. Bosch brand with short pigtail. I'm gonna get mine out of the header and take it down will let you guys know what I find. | ||

"I gotta tell ya it really burns me that I have to spend an extra 250 to get the bike to run "right" I know the responses and yeah that's all fine and good but really it's straight bull and we all know it." -boogiman1981 You can thank the EPA, stock tune has to pass epa regs, Erik Buell Racing ecm does not. stock tune- make the bike run best for the environment Erik Buell Racing tune- make the bike run the best it can, coolest, right AFR regardless of emissions. | ||

well it still sucks regardless of who's to blame... i bought this machine expecting it to perform not behave like this... | ||

Some aftermarket oxygen sensors that work on CR & R: BOSCH 12014 (0 258 002 014); Denso 234-1001; NTK 21002 These run at about $20. Check Amazon. | ||

Purely speculation, IMHO it's not all EPA to blame; most of the issues can be attributed to the 2+ year learning curve the factory had with understanding how to properly set up the new ECM (DDFI3) for a (new design)Helicon engine. There were similar problems with the XB's with DDFI3, just not as bad because it was a familiar engine design they had plenty of experience with. If you look at all the ECM calibrations progressively from the beginning (2008 MY release)to the last, it's obvious this was an ongoing development period. The OEM calibrations were getting pretty close when HD slammed the door shut in late 2009; if the factory was still alive today I think the newest OEM calibrations would be nearly as good as Erik Buell Racing calibrations are, or maybe even better. | ||

thanks Dc i agree Lampo | ||

Motorcycles have been running like epa/crap for decades, it goes with the territory. |
