Thanks, I was hoping you'd say that!

 

I just ordered a K&N RK-3909 from AutoZone and a set of Vance & Hines Basic Slip-Ons from M&M Cycles. What I am wondering is what the actual (approximate) AFR is for a setup similar to this with the XiED's installed using a Data Analyzer connected to some Wideband O2 Sensors. Has anyone checked this?

Thanks

 

Andy (Rider57) would be the one to ask about your K&N RK3909.

 

You should be ok but, why WBO2 and XiED's? AFR should be around 13.5:1

 

Well I think I contradicted myself asking about using WB O2's to measure the AFR. Thanks for the info.

 

I've been keeping up with this thread from day one and I want to share my experience. I've got an 08 Ultra with 6000 miles and have run the IED's for most of those miles. During that time I ran the stock airbox and filter and SE slipons (80491-07). It completely changed the bike and I could not have been happier. About a month ago I decided to try the XIED's. Imediately I could tell the bike was running richer. Any slight popping on deceleration was gone, the temps were slightly cooler by the IR gun, but for my setup it seemed to be richer than what the bike wanted. It lost some of its snap and seemed to labor a bit more while cruising. So I tried the K&N replacement filter (HD-1508) and there was a substantial improvement. Roll on throttle is stronger than ever before but the initial snap and crispness is not as good as with the stock filter and IED's. Another interesting point is that at max throttle in 5th for passing, the bike pulls harder with the stock air filter. Must be because in open loop mode I'm not adding any more gas with all the extra air the K&N is flowing. But as is for my setup, I am most happy with the stock airbox and filter, IED's and SE slipons. A friend has a PC111 for sale-maybe I'll do some more experimenting...

 

I ordered my XIEDs on Thrursday night and recieved them in the mail on Monday. All the way from Florida to North Idaho. Unbelievable service in my book. And we are finally going to have riding weather this weekend. I am really looking forward to trying them out.

 

Thanks. Running the true duals. I remember reading about your ordeal. I've been crossing fingers, rubbing lucky rabbits foot, and whatever else I can think of to ward off the evil heat shield demons!

Ain't it the truth about going backwards! My experience, not so much with bikes, with cars has always been if I didn't feel like a mod had netted much if any gain in performance. Stay with it for a week or two and then go back to the previous setup. This nearly always revealed a gain. For some reason it just seems more obvious going backwards when it's a moddest gain, at least to me anyway. Wonder if I need my butt dyno recalibrated?[8D]

 

05LowRider:

I think you'll be just fine and not have to worry about the heat score demon with the XIED's.

 

Just ordered the Xied's for my 07 FXD with 2.25 rush--big sucker a/c--fuelpak and no hd download. As heywood said--the fuelpak does not cover the closed loop mode but does cover the open loop mode. I will add the Xied's to the bike along with the fuelpakto cover the closed loop mode and give you a report. I really appreciate all the info from you guys!
