All right, this could be something, could be nothing. My XB9R, when still relatively cool (less than 5 minutes riding) will bog down at ~4000RPMs when I nail the throttle. It's never done this before. It doesn't do it when I roll it on, only when hitting it hard. A friend of mine said that his X1W exhibited the same symptoms when his O2 sensor went bad. Could that be what's causing this? I'm loathe to replace the O2 sensor without being at least somewhat sure that that is what it is, I'm sure it's a bear to get to on an XB. The bike's got 13,500 miles on it and the engine's never been rotated down before. Thanks, guys! Bryan | |||

bryan, you don't have to rotated the engine ( i have taken my'n O2 sensor out yesterday evening, to tighten the headerbolt's ( the where loose ) took me about 1 hour ) support the rear ( hang it up ) take out the rear shock , rotate the fan out. and presto you got access to the O2 sensor a O2 sensor tool will be needed !! gr, and good luck bud ps. i don't think that's the problem. the o2 sensor is starting his regulating thingy just above idle beter Tps it first ( and read out the value's AF should be from 115% up till 121 % with racekit) iff it's to rich up from 125, manifold gaskets or header gaskets ( my'n where loose as well , but i hade a different problem ) edited by bud on August 19, 2003 | |||

Darthane, Doubt 02 sensor is the problem... your problem seems to be quite common.... look here www.americanthunderbike.org kk//kef | |||

Hey Darthane I had the same problem, I work for my families HD/buell dealership and it took me a couple of weeks to figure this problem out, because the bike wasn't throwing a code. What it was in my case was the engine temp sensor was not allowing the bike to throw a code. After changing the engine temp sensor the bike then threw an o2 sensor code. After changing the 02 sensor the bike was 100%. 99.9% sure its the same thing. I have become a master with the digital tech from reseting my tps and checking out my AFV numbers when diagnosing this problem; Make it easy on your self and check the 02 sensor. edited by NYJS on August 19, 2003 | |||

They're cheap, so I have no problem buying the part and replacing it even if it isn't the problem, it was more I didn't want to involve myself in the labor necessary, but from what was said above, it's less involved than I thought. What is this O2 removal tool, though? You can't get a wrench or socket in there? Also, the engine temp - you mean the cylinder head temp sensor? How much was that? Thanks! Bryan | |||

bryan, something like thise  i don't think you get a spanner in gr,m | |||

Ahh...would a crow's foot work? What size is it? | |||
| Bud |
crow's foot ??? never heard off, i don't think you mean the flapping black kinda animal feet  size 22 mm. gr. | |||
| Darthane |
Bud, A 'crow's foot' is a socket very similar to that picture you posted but it is open ended like a wrench. 22mm? Damn...ain't got one of those! This means I have to go to the hardware store...CURSES! -=silently shouts in joy=- | |||

Bryan, My 9R does that hesitation sorta thing too like you described it. It also exhibits a randomly occurring temporary high idle, ~1500, when hot sometimes. Tat from American Sport Bike said that an O2 sensor with about 10k miles will start to deteriorate in performance by taking longer to react to changing conditions. Since mine's got 13.9k miles, he suggests that I should change it out ASAP to sharpen the bike's performance. Gotta get that offset socket first though. Sparky | |||

I'm planning on putting the nallin kit on this weekend, which includes the hipo O2 sensor. What kind of socket do I need? any old parts store carry that?? thanks | |||

Apparently you need a 22mm crow's foot or suitable replacement. This is assuming that the housing size on the HiPerf O2 Sen is the same as the 'standard'. Probably, but who knows? Sparky, yeah, I'm prolly gonna replace it soon. O2 sensors are kind of 'throwaway' items, they degrade with age (no surprise, given the environment they live in). I'm at about 13.5K on mine so it's probably due even if that's not what's causing the issue. He needs a TPS reset as well. -=shrugs=- edited by darthane on August 20, 2003 | |||

Bud Here is a crowsfoot rench.  | |||
| Bud |
ok, another us slang word learned  luckely i work in a autoworkshop, borowed the O2 socket from my boss ( never brought it back in & ordered a new one ) i'm always looking around the workshop for special tools that will fit the XB. perhaps you can use a 22mm ringspanner as well, ( bend it a bit ) it's only needs to loosen the first 1/2 turn after that you can almost turn it out by hand gr,m ps. i'm gonna try a other O2 sensor also. (21000 km) i'm not shure that my inlet gaskets are leaking, i have sprayed some wd40 on theme an there was little or no change. but my AF keeps getting richer every time, and then the bike holds back and stumbles. and replacing the inlet gasket is a job where you have to pull the engine down. | |||

Hi everyone here is a link to some info . 99x1 posted 02 sensor tesing here on this board.Hope this helps.

I would be pretty leery to use a Crowsfoot or an open end wrench on a large fitting which is prone to rusty threads. It would be very easy to round off the flats on the sensor if it didn't come out easily. And, yeah. I'm having the same problem at 7500 miles. I had the airbox cover off recently and may have pulled the air intake sensor leads loose. Is the AC-Delco/Bosch cross reference good for the XBs also? From an earlier post: >>cross reference a 1992 Chev pickup / AC-Delco AFS-20 / Bosch 12014<< edited by bykergeek on August 20, 2003 | |||

Does anyone know if the X1 and the XB used the same O2 sensor? |
