O2 sensor wires

Installed new exhaust on my 2016 48. Seems that the O2 sensor wires are pretty tight now and with that they are touching the exhaust (no heat shields). So with that said should I be worried..is there any chance of melting at all?

I am assuming the black protective sleeve isn't heat resistant. Just wondering if I'll run into issues if I dont get them out the way somehow.

Cheers!

You definitely do not want the wires touching the exhaust. They will melt with out a doubt. First thing I would do is see if you could route the wires a different way to gain some length. If the new exhaust moved the O2 bungs that much you may need to extend the wiring harness to accommodate this. If it comes down to that just make sure to use the same size wire so it does not mess with the readings from the sensor. Good luck!!

Be careful extending those wires, I read that the O2 sensor actually emits heat through that wire and could cause a fault code to appear if you simply splice a piece of wire in. I'm not an expert, but I've been having trouble with my rear O2 sensor and have done a great deal of research on that issue. You may want to call HD and see if there is an extension made, or make your own heat shield to protect the wire. Just a thought, like I said I'm not a HD expert but have had a great deal of problems on my 07 Sporty with the rear O2 sensor.

Actually O2 sensors breathe thru the wires, when clogged the sensors won't last long. If you want to extend wires do it on harness, not on O2 sensor wire.

unplug and re-route

I usually unplug and re-route my O2 sensors. there is a good amount of slack in the wiring too, it's all just tied to the frame with clamps and zipties.

You don't want them tight, and for sure not touching the exhaust.

Thanks for the input. I'll look at rerouting as an option. I was thinking of adding some shielding to the wires that's rated for high temps but that may be a bad idea then with the fact that the wires need to breathe?

Cheers
