Hi guys,
I posted a while back saying my brother was going to put ied's on his 08 Roadking, he lives in Ireland where the temps only get to about mid 20's. Anyway he put them on and loves them, the bike runs much better esp. in 6th gear and the throttle response is better, he is going to Europe in June where it will be warmer and can't wait to see the benefits then. The question I have is,the bike is due its 1000ml service and he wants to know if it would be ok to leave the rear ied on and just take the front one off as he does'nt want the dealer to know they are on,he thinks they won't see the rear one. Would it do any harm to leave one on and one off? Thanks again for your help guys.

 
 
I would take them off.

The only thing that might not be same is I don't have the parade download(if that's what it's called, the one that shuts fuel off to rear cylinder).

The parade mode has been in the bikes ECM since 03 or 04 I think. It was a one time download from the dealer for the EFI bikes. You should check it out.

You should be able to get it activated if you really want it.

I did not know this.  How would I go about finding out if this is the case on my bike?  How do you activate it?  Not that I think I need to use it, but it would be nice to know.

Well, I have just over 10k on the bike now and I can't say I have ever noticed the rear cylinder turning off and I have been in slower than parade traffic in rush hour getting out of downtown Chi town.  Would there be more info on this in the service manual?

I've been following this thread for quite some time, so I thought I'd add my experiences.

I have been riding Harleys for quite a while, and have done extensive mods on all of them (I used to build race cars and motors). My previous bike was an '04 FLHRCI that got a 95", head work, cams, DOherty PP, V&H, PCIII, pistons, etc...that ran very well.  My point is that I know the basics of these motors.  I also know to monitor spark plugs for a good real-time indicator as to what is happenning in the combustion chamber. 

More to the point - I sold the RKC and now have a new '08 FLTRI that I will keep basically stock until I see if this Chinese crankshaft stays in one piece, or decides to "twist", take out the oil  pump, and grenade the motor (known problem).  When  riding the new RG home I immediately noticed the extreme heat being generated by this new '96 motor.  I live in central Texas, so heat is a major consideration in these air cooled motors here.  After several hundred miles I pulled the plugs, and was not suprised to see them coated in a white ash,  indicating a very lean condition.  Wanting to keep the warranty, and my motor, intact for a while, I researched the heat issue and found the Nightrider site.  I purchased a set of the IED's, gaped the plugs to .040, and rode a few more hundred miles .  Pleasantly, the plugs were showing a much better combustion environment, the motor ran better in many ways, and my right leg had quit sizzling.  I considered this an acceptable way to save my motor and  warranty, since the IED's could easily be removed for any visits to the dealer.

So along comes Steve with the "better" XIED's.  Not being able to leave a motor undisturbed, I installed the XIED's, and a Ness Big Sucker Stage 1.  I selected this air cleaner because it has the chrome 1 piece backing plate with integral vents, and it flows a little more cfm.  Knowing that more air = leaner combustion condition, I hoped that Steve's XIED's might "equal" things out. (still stock exhaust).  I ran several hundred miles with the "new" setup, mostly 40 - 70 mph with very little idling, none in the final 40 miles, and checked the plugs again at the end of the ride.  And to answer the obvious - yes I shut the motot off immediately after stopping, it did not idle for than 15 seconds.

Here's where it gets interesting - the plugs were DARK - not damp, but certainly indicating a rich AFR.  With the new AC, I was expecting  a semi-lean or good AFR.  The bike ran good, but I'm not sure it was better than the IED's with stock AC.  Logic would say that since the XIED's allow the bike to run a little richer than the IED's, an AC that flows a little more air (leaner), would offset the richer condition, and the bike should run better, or at the least not richer than it was.  Mileage dropped from approx. 45mpg to 42mpg, so the XIED's were doing their job.  I was riding solo, so I don't know if the exhaust "smelled" rich.

I found this to be interesting since getting these new motors to run "rich" without completely bypassing the O2 sensors seems to be impossible.

The next step will be slip-ons to see if that will "lean" out the AFR a little more.

Thanks for all of the great information everyone has disseminated in this thread.

Nice bike....NICE PIPES...lol

Are you running TD's ,slip-on's, or cross over? You've got to be real careful if they're the True Duels. Those pipes are a different animal when it comes to getting the AFR right. It's already cost Bub $127 for a heat shield.

How can the AFR be changed (get it right) if the only addition was the XIED's?  I am running true duels on mine without the use of a fuel pack or other.  Would it be by changing the slip ons to get the righr back pressure?  Or is there something else besides going back to the stock cross over?

The Bub7's are bigger than normal true duels. 1 7/8 vs 1 3/4 like most. That together with HD not having a TD map for the stage 1 to boot on the 08's is the difference.

They didn't want to try an older map because of the FBW set up in the 08's and they probably won't try it due to EPA concerns. I thought of that as well. All the tuners are playing catch up with the FBW system. Most of them are just starting to come out now, and even those look like there are a few bugs that have to be worked out according to some of the other threads I've glanced at.

The 07's still had the race version of the map avalable to them. You should be fine. Not as lucky with the 08's. The lack of a TD download + the difference of the BUB pipe is the difference. What I was talking about is really specific to 08's and BUB TD's.

The pipes can have a an effect on the AFR when coupled with the Hi-flow A/C. Stock pipes with the hi-flow will put it on the richer side. Same with stock a/c with aftermarket pipes.

Cruiser, just an observation after several hundred miles with both the IED's and the XIED's, im running a stock 07 Screamin Eagle Ultra with just a slight change to SE Street mufflers still epa compliant. Although the bike runs much better with either set installed, Starting, Idle and low speed maneuvering, is better with the 14.2's feels more refined. Im sure each individual bike has tuning differences but in my case the IED's seem better suited to my riding style.
