========================
" I don't know what else to do besides replace the o2 sensors "
Dude,Your kidding right?/Geesh!/LOL!!!
AH,just busting your chops!
Anyway,After taking the time to write out detailed instructions along with mult testimonials for you to see what i rec has worked out for me along with how to use my 1st rec cleaning procedure to clean excess carbon & contam from the combustion chambers & then after that how to do the 2nd cleaning i rec using cat & o2 sensor cleaner to remove carbon & contamination from the 02's that in many case cleans the o2's well enough to stop getting chk engine lights and emission type error codes too.
So before going any further & or deeper into this spending considerably more money to do so why not follow the steps exactly like i rec in my prior post in this thread to see if it helps your bike?
1st run a full tank (if poss 2 tanks would be better with 100k miles) treated with Chevron Techron (States " Concentrated " on label!) of 9oz for 6 gals fuel and then a full tank treated with the cat & o2 sensor cleaner too @ the dose rec i already stated in my post ans your question on where to get it etc.
If possible it you would best cleaning to run those tanks of fuel for both cleaning procedures at higher speeds/higher cruise rpm on open road because that will generate hotter ex temp and more exhaust force /CFM flow going thru the exhaust system at the same time too setting up best case situation for max cleaning efficiency in the engine and then on fine wire the 02's are made of too.
Then after your done doing both cleaning procedures i rec above put on another 100 miles or so on a fresh fillup and then clear the codes again & go for a nice 50-100 cruise to see if chk engine light comes on again & or if emissions type code relating to 0'2 sensors re-appear again in which case you may need to replace the 02's due to being so gunked up for so long without cleaning srvc like i rec that they are past point of no return which could be the case.
But trying to clean them up using my 2 step cleaning rec costing approx $30 for the cleaning solutions is easy & cheap that at the very least with clean excess carbon & contam from combustion chambers-pistons-backside of intake valve along with also cleaning 0'2s too making the motor run smoother with better throttle response along with little better mpg too.
And best case would be if it also got rid of the chk engine light & or emission related error codes your bikes getting too.
Good luck and let us know how this turns out if you decide to try it with nothing to loose giving it a shot.
Good luck.

The bike ran poorly for 30 seconds or a minute after I washed it. That's when I checked and the codes were there.
I unplugged the connectors for the o2 sensors lastnight and cleaned them with electrical contact cleaner. Rode it to work and that's when the 3 codes came up. I just took the fuelpak off at lunch and will ride it home and see if the codes come back. Will probably stop by a auto parts store and get some techron cleaner and o2 sensor cleaner.

Good luck getting it sorted out... sometimes it takes time, but you'll get it....

Thanks. One thing I forgot to mention was that the engine was replaced with a brand new engine about 25,000 miles ago. But I'm pretty sure that the o2 sensors are original.

I made sure they were plugged in correctly. Yes, I have the stock headers which have no cat.

I disconnected the fuelpak at lunch today and rode about 15 miles home after work. The po131 code came back but the po132 and po152 codes have not come back yet. Going to ride to work again tomorrow without the fuelpak and see if the other codes come back or not.
wscott,
I also stopped by autozone and got some chevron techron injector cleaner and the cleaner for the o2 sensors. On my first tank of the techron now.

I would have to look. The exhaust is exactly the way it was when I bought the bike. I haven't done anything to the exhaust on the bike. But I can look.

Thats great the 2 of 3 codes have not return yet.
You said you added the techron yesterday and am trying to see if codes will stagested to mtry cleared today?
Thats not near enough time running the 1st let alone 2nd of the 2 diff type cleaning procedures i rec you try and not the proper way to do it at all.
You cant rush it & have to be patient because its a process you have to do & follow step by step to have any chance of getting the great results like i posted .
Thats why i gave you step by step instructions to help you out.
So if your trying to see if the codes with stay cleared without running at least 1 full tanke of fuel treated with techron along wqith not running the 02 senrso cleaner after that how can you expect it to work when i already told you to run at least 1 (better yet 2 ) full tanks fuel of treated techron (concentrated version @ 1.5oz perg cal/9oz to 6 gals fuel) thru the motor then after that to also run a full tank of fuel treated with cat & o2 sensor cleaner which sue looks like you not doing 7 expect to get good reults when your not following instruction?
Then after doing the # 1 & 2 cleanups i then said to fill it up again (would be 3rd or 4th full tank) of fresh untreated fuel at this point & run the bike approx 100miles & then clear the codes & see if any emission related codes return after that.
Maybe since there has been multiple issues with re-occurring emission related codes maybe it would be a good idea to also remove a battery cable for a min or 2 to in so many words " reset the main ECM" (to ensure the ECM isn't stuck in some sort of loop ) after you clear the codes after getting approx 100 miles on the last tank of fresh untreated fuel post doing the 2 prior cleaning procedures.
Good luck.
Scott
