Plugging O2 Sensor Holes

[ozsn]

Any ideas for what to use to plug the holes in the exhaust for the O2 sensors? Mine keep coming loose and since I have a PCV they aren't connected anyways, so I would like to just remove them completely. Is it as simple as just screwing in a bolt of a certain size? Thanks for the help.

you can buy plugs and here is the size. M18x1.5. you can do a search or purchase them online or parts store.

Thank you.

I was going to say, yes, they are probably M18x1.5 plugs that fit most Bosch O2 Wideband sensors.

Here is another source.

Of course, you could leave the O2 sensors in place as well.

You might want to consider safety wiring them, I noticed that Akro does that for you on their systems.

Meh...

Never had one go rampant on any bike whatsoever. More interesting stuff to safety-wire are drain bolts and filler plugs, timing hole caps, engine covers and other important ones.

Assuming TS has a full-system, you can completely remove the servo cables and motors too.

Edit: And to be extra clear

It doesnt trigger a fault. Removing the O2's triggers exactly the same type of code that the servo's do, and thats just a logged fault in the bike's fault log, which is only visible by the dealer or GS-911. It doesn't trigger a limp home mode, and it does not trigger a light. Stuff that triggers a light (and at the same time the safe mode) are important faults, like errors in the primary fuel injection sensors, errors in the ride-by-wire system/electronic throttle valves and ECU faults.
