An oxygen or O2 sensor is an important part that measures oxygen levels in your motorcycle fuel to tell if your engine is running rich or clean. This can be key to getting the best power and fuel efficiency out of your Harley-Davidson motorcycle.

Whether you're existing O2 sensor is failing or you need to add this part to a new build, we stock a great selection of Harley-Davidson oxygen sensor models.

Motorcycle Harley-Davidson Categories All Categories. Exhaust 2,By TraceApril 12, in Modifications. You can make your own Oxygen sensor eliminators by installing ohm resisters across the leads to the OEM sensors. Locate the natural and the black colored 4p connectors near the alternator cover left side and dissconnect them both.

The 4p connectos have 4 leads. Use the two leads opposite the locking tab on each of the black and natural connectors, obviously on the side connected to the bike and not to the O2 sensors. You can remove the sensors and their wire harnesses if you want.

Plugs that fit where the sensors screw into the exhaust pipes are easily found at most any auto parts store. You can wrap with electrical tape or find large shrink wrap to protect the wireing job, zip tie them secure. My guess is, it will prevent the bike from leaning itself out because it doesn't detect the rich mixture anymore.

I asked a similar question on another recent thread and am impatiently waiting for a response. Does the bike run richer overall, but without the Cat produces more hp? If one were to simply run eliminators on a bike with a Cat and no PCIII, what would happen, assuming no aftermarket pipes? Inquiring minds want to know! I really know very little about the intricacies of the FI system and have learned a lot from some of our more technical folks at VFRD.

As always, I appreciate the info!! It is thought that eliminating the o2 sensors cures that midrange surge or flat spot in the power-band. Using an aftermarket silencer some have had success in curing the surging by eliminating the O2 sensors. When in constant throttle the ecm puts the fuel curve into stoichiometric mode and it burns with lower emissions, saves fuel, this seems to produce a flat spot or a surge when coming out of it.

Thanks HS. I was looking for a bit more ed-u-ma-ca-shun on how it actually worked in terms of various throttle situations so I appreciate the help. So my question is, if the Cat is not there ie 99 header pipe and the sensors are eliminated, does the bike run leaner, regardless of throttle state steady, WOT or does the bike run richer?

It seems the removal of the Cat would decrease the restriction enough to require a change in the mixture assuming factory exhaust and no PC III. So, to complete my ramblings, if I were to get 99 headers, with no aftermarket pipes and no PC III for my Vtec, would I notice any positive or negative performance changes hp or will it simply be enough to address surging problems for those unlucky owners that have them?

Map Sensor is what controls the fuel air mixture mostly, but it hands off to the O2 sensors when in open loop during those steady throttle sessions then it goes very lean into stoichometric, it think its 14 parts air 1 part fuel. Map sensor measures the manifold vacuum pressure which is what controls the fuel mix when tied with the throttle postion sensor - its a three dimensional map tp sensor vs map sensor air temp sensor in the airbox - it is when one of these variables is held constant that the O2 sensors is used, TP constant input for so many seconds loops in the o2 sensors.

The computer needs to know the volume of air at what pressure and temperature in the cyclinder to inject the right amount of fuel based on the throttle input at the time of the intake stroke.

Its of course more complicated than I explain but basically thats the idea. When I installed mine I ended up nipping off a little of each lead so that the resistor can sit right on the end of the connector. Makes for a little cleaner tape job. This was more for demo purposes, so a person could see what terminals to plug in to.

I also want to mention that there is no need to mummify the connectors with electrical tape to keep water out. Just use a little bit to 1 retain the resistor and 2 insulate any metal from shorting out. Too much tape will likely trap water inside the connectors and lead to corrosion someday. And water won't really hurt anything, anyway. Instead, let them be "self draining". Engine heat will dry 'em in a minute. Besides, once you pull that clear plastic boot back down over the connectors, water won't be an issue anyway.

I think it is all making sense now. So if I put on the new -old headers, and used the O2 sensors, I wouldn't really see much on the bike performance wise. My bike would just run closed loop at all TP and I might get a bit more sound from the stock cans?Orders placed during the weekends or the following holidays will ship the next business day.

In Stock Only 1.Typically found in a motorcycle's intake and exhaust system. An oxygen sensor sends measurements of the amount of oxygen flowing into the intake or exhaust system to the electronic control unit.

The ECU then adjusts the fuel-to-air ratio for performance or emissions-related purposes. Most fuel-injected motorcycles run on a predetermined fuel setting with small adjustments made as oxygen levels change. At higher elevations, for example, the ECU would adjust the fuel delivery against lower oxygen levels. Replacing the stock exhaust system with an aftermarket upgrade may cause problems if a mounting point for the O2 sensor is not present. An O2 sensor eliminator kit is recommended to prevent incorrect O2 sensor readings.

Tuning the fuel-injection system is possible with a stock O2 sensor through the use of an aftermarket fuel-injection controller, allowing the user to set the fuel curve as desired. The capability to produce an ever-adapting fuel injection map is possible through the use of a properly equipped fuel-injection controller and O2 sensor. Designed primarily for closed-course racing, this type of system could produce a strong power curve against changing conditions.

Next time this happens, check to see if you have spark ; both front and rear cylinders. You might have a bad coil, or a failing crank position sensor. If it is fuel related; look into replacing your fuel filter, or test to see if you have correct fuel pressure to your injectors. I have a Ultra Classic, have had it for 6 months miles.

I have a Harley Dyna Super Glide. It has 02 sensors. I am wondering if the Vance and Hines FP2 will work even though it says and newer. Can anyone help me before I purchase? I have a sporster. I am going to take plate off trans. Hi, Gary. Your drive belt broke. I am looking for clarity on the O2 sensor issue. I have a Fat Bob. I keep seeing dissussions about the next step being to remove my O2 Sensors.

What are the advantages and disadvantages to doing this? Really, keeping or removing O2 sensors is a case by case thing. However, in most situations, with an FP3, it is more beneficial to utilize the O2 sensors. You will achieve a better tune. Also, you will not be able to utilize the auto tune feature without your O2 sensors. I just changed my exhaust on my 16 sportster custom.

Now my engine light is on.
