Yep, my plugs look lite brown,not so white, I heard it is best to checkyr plugs after you run up at speed,cut your motor and pull over so you can see how they look after running, NOT idling.
Tech Forum as some other good data on these IED's good investment for the $ IMO.

Anyone tried the DYN Oied's that are for the 06 year only? I'm thinking about giving them a try but can't decide.

 

Just put mine on. Saturday went for a ride and noticed a big difference. I have an 06 street bob with a Big Sucker and Cycle Shack Slip-Ons. I had a pop twice on decel, noticed that I was cruising at 80 mph in 5th gear very smooth, cooler engine (even though the day was burning hot) and all around better performance. My check engine light did come on for about 15 seconds or so and just switched off. All in all, I am very happy with everything. I even check my plugs and they looked great.

 

BRK was the check engine light a one time thing, or every time you have ridden?

 

If your engine light went on, then you probably have ECM codes: Here is how to check:

Turn everything off, turn your start/safety switch to ON
Hold the button on behind your speedo
while holding the button down, turn on your ignition (with key)
Your speedo needle will do a sweep, and you will go into Diag mode,
P 5 55
hold button when each one comes up and check for your error codes:
P0131/P0151 are usually the ones

(DOa search on ECM codes, for better,more complete instructions)

 

Check your codes.
My light came on twice on the way to work, then I cleared them.
The light came on once on the way home, front sensor lean.
I haven't gone for another test ride yet.

Sound to good , after reading all I bought it get not wait

 

thanks for all the advice. i'll be sure to check the codes.

 

Since I started this thread, I should explain what I have found since I first installed my IED's:

Before I installed my 2-1 pipes I had stage 1 download, cycleshack slip-ons and the K&N hiflow airfilter, I did not get any ECM codes and the bike ran better with IEDs.

I installed the PYTHON 2-1 and no other changes, I got the ECM codes P0131/P0151 indicating "lean conditions"

I took off the IEDs and the codes went away.( Obviously, the codes are due to the IEDs)

I told Steve at Nightrider about this, he sent me a new pair of IEDs: I still got codes.

Steve sent me a pair of DYN o2 IEDs: I still got codes (my bike is an 07 Dyna)

Steve sent me Xieds: I still get codes, but bike runs good with Xieds so I just leave them on and not get too worred about the ECM codes.

SO, my guess is that there is smething about the 2-1 pipes/IED combination that causes these codes to appear, but that there is nothing really wrong....I hope...my plugs look fine and the bike definitely feels like it is running better with the IEDs.

Steve told me h is looking into this.

BTW, most of the rave reviews come from baggers with stock intake and mybe they added slip-ons.
