O2 sensor replacement

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

The downside, especially for latter models, is a permanent MIL light. :(
Resistors can address that issue too.

I noticed the newer Urals have the O2 sensors much closer to the engine. Did they find that location to be better somehow?
Yes, they get to operating temperature quicker, and maintain it in adverse conditions such as rain, snow, and extreme cold.

If memory serves, it was to ensure they stay hot enough.

I guess the other thing you might miss with the sensor unplugged are compensation for varying O2 levels at different altitudes?

Did you do any research on the O2 sensor part number?

Good find -- those look identical for $12 less than UralNE.

I did Google, Amazon and eBay search and found nothing, I must not have transcribed the number correctly.

Anyway, despite having new ones now I think I'll just leave them off for now since the running is so much better.

Does anyone know anything about wiring up resistors in place of the sensors might require? My cursory research suggests that other sensor-equipped marques actually ship with resistors in some markets, so this should be a viable alternative to those who don't want to stare at the MIL light.

I've been reading up on it, and I think Dynojet may have a plug-n-play solution?

I don't know which one specifically, but it's probably just a matter of matching connectors.

If Ural is using same O2 sensor as some harleys, then for sure there will me an Eliminator out there.

Any experience with them? Are the connectors for a 14 the same as an 18?

A neat, easy, reversible solution, but $30 when I have 330 ohm resistors in my stash........

The connectors are the same for 2014-2018.

I was thinking I would use my old O2 sensors as connector donors for a project, but I've got more money than I have time to muck about these days, so I bought a pair of these instead:

https://cart.dynojet.com/p-1521-active- ... ro-hd.aspx

I'll let you all know how it works out. Had I known about this option, and how good my bike runs without them, I might have passed on getting new O2 sensors altogether.

Yes! Please do.

If you get a chance, could you post a picture of the connector? Don't know if they changed them when they upgraded the wire harness.

That's the O2 sensor side.

My guess is that in using this precise sensor and connector combination IMWA was taking advantage of the HD economies of scale. Changing it would likely incur unnecessary cost.
