Buell Owners: NightRider XiED

[Gas Man]

Buell Owners. They make one for you too! Read up.

Knight Rider Performence is not only a great place for bike tech but also sells a few select performance parts as well.

Their bread winner has to be the XiEDs.

Don't let the Harley heat monster ruin your riding.

I like to keep in mind the intended purpose of each bike. My Ultra is designed to trek me cross country in comfort. It is not a hot rod. It gets a bit hot and throttle response could be improved. The Nightster runs cool enough for what I notice, but throttle response sucks.

I figured it this way. I have 2 choices. First, aftermarket tuner + dyno time, which adds up to $500+/-. Gain some added power, cooler temps, better throttle response. Second, and my choice, NightRiders XiED, which will give me cooler temps, better throttle response, and maybe?

I have been waiting all year for the new 2009 FLH XiED to be certified. They finally were and I picked up a set for the Ultra and a set of X14iEDs for the 2009 Nightster.

The Ultra's, which I have yet to install. The added wire is to correct the new FLH dirty ground.


The Nightster's X14iEDs


The plug-n-play installation is just that.

Front:

Unplug the O2 sensor here


Put the X14iED inline between the O2 and the bike's wiring


Then tuck it in somewhere keeping it away from hot items


Used 2 zip ties and the existing clamp to keep it tight and clean



Rear:

Stock wiring plug here


Unplug



Plug in and zip tie into place



I added a step, that wasn't in the NightRider instructions. I pulled the maxi fuse for 15 mins. Then reinstalled that. Took the bike for a nice 15 mile ride.

First thing that I noticed was improved throttle response at idle. It use to plup then rev off idle when you whack the throttle. 75% of that is gone.

In gear, clutch out, and twist the throttle. I instantly notice the throttle response. I swear they installed a few extra power points. Couple that with the throttle response and the end result is all big grins. I'm amazed!! It feels like it added 5-10hp.

I still need to do the Ultra install and report back. I'm also going to have the brother in law ride the Nightster for a 2nd opinion (he's rode it a few times). But right now the weather is poopy for the next 4 days.

More to come...

Wish they would make these for my 5th gen VFR.

Sorry. You can email Stephen. But it sure does seem to be HD related only.

Marko... you need these!!! Trust me. It did huge wonders to the nightster!!

Looks like he's recommending the brand new modular setup.

Look like it still wouldn't cost.

Dudes website BLOWS.

Guy has always been about content more so than look. He's rock solid when it comes to tech!

[marko138]

Hmm. You've got my attention. There's a guy who makes tuning software for the XB's called ECMspy. But I've resisted because I dont really have any complaints with the throttle response or power delivery of my bike, and I don't really wanna get in to tuning myself.

But if this is as easy as it looks then I might be in to it.


What, exactly, are these two wires doing?

And, semi-related, does your Ultra have two O2 sensors? Mine only has one, on the rear header.

do they make a 1125 one though....

so how much did that resistor run? considering how well that trick works with the ebay ''chips'' id be surprised if it didnt live up to the name of ied
