Motorcycle Nightrider XiED For Harley

Got a 2007 or later O2 sensor-equipped bike? Is it running hot or pinging? A couple of these little gizmos may be all you need to fix the glitch. And all you need to install them yourself are some basic hand tools and a few wire-ties, no dyno time or downloads needed.

Each Xtreme in-Line Enrichment Device (XiED), of which you get two in a kit, is simply an electronic device that goes between the O2 sensor located in each exhaust header (you have two headers) and the bike’s wiring harness. Once installed, the XiED ($109.99) slightly alters the signal going back to the ECM from the O2 sensor. This altered signal tricks the ECM into changing the air/fuel ratio from the stock lean very setting of 14.5:1 to a slightly richer 13.8:1. (On our test bike the ratio was actually 13.7:1.) While this is not enough of a change to give any real power increases, this richer mix will help drop engine temperatures, eliminate some pinging, and slightly improve throttle response. However, this increase in fuel doesn’t occur throughout the entire rpm range of the engine. It’s only for the rpm range that the O2 sensors control, which is off-idle and most mid-range operation. It will not cure deceleration popping.

I’ll close with a couple of tips. Ask a friendly H-D mechanic to show you where the O2 sensors are located on your bike and how to disconnect the sensor wire from the harness. This will eliminate the hardest parts of the installation. And don’t worry if you get 131/151 trouble codes, which sometimes happens after the Nightrider is installed. AIM

    I’m in the process of putting on Cobra’s Power Port head pipes with no converter in pipe using stock mufflers and also putting in K&N free flow air cleaner under the stock air cleaner cover and wondering if this Xied fuel enrichment system will enrich the air fuel ratio enough so that the engine will not be damaged from running to lean? My goal is to get a little less engine heat from the hot head pipes on my wife and myself. I have a stock 2012 Road Glide 103 engine. Thanks Brad PS My Harley Dealer wants to sell me tuners and dyno time at a high price!
