Harley O2 sensors

Q: 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?

A: 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.

Related 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.

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

    I have a 2007 flhtc. After I start it the first time and ride, when I turn it off I have to wait 20 to 30 minutes before it will start again. After this it will start the rest of the day with no problem. I have changed the exhaust, could this affect it? Any help is greatly appreciated.

    I have a 2014 Ultra Classic, have had it for 6 months (4100 miles). Just purchased a Kuryakyn hypercharger intake and V & H Big Radius Staggered Exhaust and the HD pro tuner… I did some research, but the results are mixed. I am not looking for a big jump in HP or TQ. I do want to cut down on “some” heat and want to have the sound I had with my Dynnas. I just gave up my Dynas for a seat and comfort the ride gives my gal, as we are not “spring chickens” anymore…we are mid 50’s.
    juat want to know what to expect and what not to expect. also, is this something I can learn to tweek myself, without screwing up my bike. I am mechanically enclined and can build and repair, but the computer part will have to be learned. any advice?

    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?

    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?

    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 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?
