Harley O2 sensors

Question Hi, I subscribed to your site earlier in the year and find your videos really helpful. I own a 2006 Dyna Super glide. I’m doing a Stage 1 upgrade and recently I purchase Vance and Hines big shot staggered pipes the Vance and Hines breather kit and a Fuelpak for my model. I watched your video on installing V & H pipes. The only problem is that my bike doesn’t seem to have hot Harley O2 sensors. Just plugs where the sensors should be. Does this affect the install?

Answer If you do not utilize your stock O2 sensors, you will need to use O2 eliminators. They snap onto your your harness where the O2 sensors were, previously, plugged in. Depending on what type of tuner you have; you may need to communicate to a tuner that the sensors are absent. If you do not have O2 sensors in your current exhaust, you may already have eliminators.

Question SE Stage 4 on my 103. I can’t get an idle even after a master tune getting 109 hp. I have the 58 mm TB and big injectors just like the kit comes with. Can I get this right getting it mapped or is the combo just to much. You would think Harley would not offer it if it weren’t right. ????? Any good advise. Makes real good power but want idle.

AnswerIf the bike runs good but you can’t get it to idle, it’s not tuned correctly.

    I have a 2007 Superglide with a V&H 2:1 system. I’ve been trying to resolve an annoying rattle that comes from the front chrome heat shield, as soon as the bike warms up. If I run without the heat shield - no rattle. No crack is visible when the bike is cold. Is there a history of cracked spot welds that hold the hose clamps on? (I’ve talked to V&H but I installed the system 5 years ago so no more warranty)

    I have a 2009 VRSCAW V Rod and just recently ordered the Power Vision as part of a Stage 1 upgrade which came with some Tab Staggered Turn Out slip ons (unbaffled), which I just installed. My plan was to hook up the Dynojet Power Vision, install the slip ons and new air filter and insure good AFR tune to my bike. However, I am beginning to realize that I am in need of wide band 02 sensors as opposed to the narrow stock sensors as well as another $549 Target Tune kit in order to properly tune my bike. It seems that I may even have to weld (out of the question for me as I'm not skilled or equipped to do so.) In your expert opinion, what should I do? I want my bike to run at its best to accomodate the new Stage 1 changes made to it.

    I have 2003 electra glide standard,i want to know if i could put a 2 into 1 d&d fat cat on even though my bike has a carburetor on it? And if so do i need to plug the 02 sensors.

    I just purchased a 2018 Street Bob. I live in California and want to get aftermarket pipes. The pipes I am looking at are not legal for California public roads and they do not have O2 sensors. If I get these pipes, what do I do with the sensor plugs for the O2?

    I just changed my exhaust on my 16 sportster 1200 custom. Now my engine light is on. What could be the issue? We are assuming the 02 sensor got twisted... any ideas and how to fix?

    I am looking for clarity on the O2 sensor issue. I have a 2014 Fat Bob. Added Screamin Eagle Slips On's, Arlen Ness Big Sucker and cut out the cat. I then added a V&H Fuel Pack. I keep seeing dissussions about the next step being to remove my O2 Sensors. What are the advantages and disadvantages to doing this?

    Hi, Please help. I have a 2006 Harley Dyna Super Glide. It has 02 sensors. I am wondering if the Vance and Hines FP2 will work even though it says 2007 and newer. Can anyone help me before I purchase?
