My 09 did the same thing. I re routed the 2 engine vent tubes outside air cleaner, cleaned intake and idle valve and away she went. Runs like a new bike and air cleaner and intake is not full of oil anymore.

 

I just had a very similar issue on my 09 Ultra with about 46,000 miles and stage 1; however, mine was not as bad. My idle would range from 820 to 10xx and I would get the choking and surging. I have VIEDs from Nightrider - removed them and the bike ran fine. Put the VIEDs back on and the symptoms returned.

I spoke with Steve at Nightrider and he said (at least my understanding) that over time O2 sensors deteriorate due to temperature and while it may not be time to replace the O2 sensors the XIED expects them to operate within certain ranges - as they age they no longer operate in the appropriate range.

Two things you can try:

1) Ensure the grounds for the XIEDs are good (I think it has something to do with the floating ground situation in the 09 ECMs)

2) Try to pull the XIEDs and see how it runs - mine ran fine (I just took the VIEDs off again this morning).

this makes a lot of sense, I have never been a fan of those XIED'S, Now I have another reason.

 

All that being said, I really like my VIEDs. Had a PC5 and two separate dynos and overall the VIEDs provided better results - I know the purists will say no way, but I was able to adjust them just as needed.

 

What LP said and also check the little rubber cap on top of the intake, when it gets cracked or pops off, bike runs like chit, worth a shot, hope it helps brother.

 

Update:

I removed the air cleaner assembly and sprayed carb/choke cleaner and cleaned out the throttle body. I sprayed the WD-40 around the intake, no leaks. The rubber cap is intact, no cracks. I took the ground wire for the rear cylinder ExIED off the negative side battery and ran the wire to a chassis ground.

Started the bike and ran through a series of start/stop cycles to see if the problem returned, and ... it did not.

One thing I noticed was the Engine Temperature Management System was functioning, before it wasn't.

So it looks like it was a combination of issues that hopefully have been resolved.

Thanks for all the good advice.

Stay safe.

 

Please explain exied . thanks.

 

==========================

I had same issue with my 09 96" with se ac and slipons when i 1st got the bike,motor ran good other then a somewhat unstable crappy idle ,bike had 9700 miles on it at the time.

New plugs didnt help and air filer was clean ,i cleaned throttle plate etc,still no good.

Fresh fuel,NG

Ran a healthy dose of chevron techron (concentrate version!) @ 1.5 oz per gal fuel so approx 9oz techron with 6 gals fuel .

I did that to clean injectors and carbon from intake valves which helped quite a lot getting back to approx 80-85% normal good ilde.

Then i ran a dose of cat cleaner in full tank of fuel to clean any crap the techron blew out of the cyls onto the 02 sensors ,that took care of the other 15% poor idle issues so it now idle is normal/stable at 950-1k rpm all the time.

Its been approx 2,500 miles since i did that cleanup/out treatment of the injectors/com chambers/int valves & O2 sensors and its still idling & running great getting good mpg too.

Avg 41-42mpg bumping arround the countryside at 50-60mph never hitting 6th gear along a little stop go traffic here & there too riding 2up.

So if you haventy yet cured the funk unstable idle try running fuel low and filling up with fresh fuel & then do the 2 things i mentioned above (1st concentrated techron then cat-02 cleaner) to see if that help.

I look at it this way,it cant hurt to clean injectors & carbon out of motors comb chambers and off intake valves with chevrons concentrated techron along with also cleaning the crap/carbon that gets deposited on the 02 sensors on the way out of the motor & ex system from just being cleaned off the 02's so they return proper 02 data info to the ECU / fuel management system .

I do that a min of 1x yrly to all my EFI vehicles inc now my EFI HD too.

All the vehicles i have done that to have not has any 02's or converters go bad at well over 100k miles with 2 of them going over 200k miles still having the stock original 02's and cat converters & running well.

Same goes for the injectors on above mentioned cars,no issues at all with them inc the 2 cars that have over 200k miles on them still running great.

I have had great results doing that clean process 1x-2x yrly on all my efi vehilces over many yrs and not having to reaple a single 02/injetstor/or cat with all high mile cars .

So with that in mind having no fuel system emissions related issues with mult cars over many yrs i have to say doing that cleaning procedure with techron & then cat/02 cleaner keeps the motor running well at their best at all times too.

Now that i think of it i havent had to replace any elec fuel pumps either even on the 2 200k mile cars either,i see a pattern here!/LOL!!

But i do keep up on fuel & air filter changes & oil / filter change maint too.

======================

I believe the Xied's are "resistors " that you install between the 02's and ecu that fakes it out to ever so slightly enrich the fuel mixture by an x-amount all the time talking the cheaper version.

But they also make a more expensive version you have some control /can adjust( to a point) the amount of enrichment the motor will see,but again thats all the time.

So fuel mileage should suffer a bit but would think too much with the afrs i see they advertise the Xieds as running at on avg.

Well yes but not always on the 02 getting older statement & heres why i say that from 1st hand exp with same yr bike & very high mileage cars still running stock original 02's because they last a very ong time when kept clean which is key which is something most people completely over look,same goes for injectors too.

I say that because what also happens is over time most people dont to regular inj and os cleaning like a min of 1x yrly so over time a lot of crap/carbon etc is deposited on the 02 fouling them well before they go bad.

I have taken low mile motors appart for other reasons and been very surprised at just how gummed up the the backside of the intake valves are and comb chambers / pistons & faces of the valves too.

As i stated in my earlier post here my 09 96" also had a poor unstable idle along with some surging & hesitation in stock form with se ac and slipons when i got it with stock ecu setup & 9700 mmiles on it ,tried plugs etc but no help.

Did my inj clean thing with chevrons techron in concentrated version 9oz to 6 gals fuel and then did o2/cat clean using a healthy dose of cat cleaner and WALLA!!!!!

The motor now idles at a stable 950-1k rpm running nice and smooth with no hesitation or surging anymore with poor idle like it did when i bought it with only 9700 miles on it.

Been approx 2500 miles since then and motor is still running great at all throttle positions inc idle along with getting good mpg too.

I have 2 cars with over 200k miles still having the original 02s /original cats/ original injectors etc because i clean inj & o2s 1x-2x yrly as i stated earlier in this thread.

So maybe that will help this guy out and even if it doesnt fix it running the 2 cleaners cleaning the inj/o2's/comb chambers/int valves is a good thing to do anyway IMHO because fuel inj's & o2's getting fouled is a very common issue these days esp with todays crappy pump fuel with ethenol.
