Getting ready to install exhaust on the 09 SEUC.
Have never dealt with O2 sensors before.
Do you need a certain wrench/socket and or tool to remove them?
How fragile are they?
Will a little oil (WD40) help with the removal?
Do I need some "locktite" to reinstall them?
How tight?

Here's pic of the rear and the front.

Thanks

Chip they do make a special socket for them. I think you can use a line wrench also. I will get in touch with Axil and have him send you a PM.

the best way to remove them is after you have removed the "old" exhaust system. first unplug them from the harness, then remove the exhaust system from the bike. you can use a regular box end wrench (or open end wrench) to remove them.
install them into the new exhaust system before you put the exhaust on the bike, use antiseize compound on the threads of the O2 sensors before you screw them into the exhaust or they'll sieze in the exhaust pipe from the heat and you'll never get them out without damage to the exhaust.

Cool!

I can go back to the garage and look or you can just tell me,
Where do you unplug from the harness?

I have a different bike than you, but the wire on the O2 sensor is a little over a foot long, then it plugs into the harness. follow the wire from the O2 sensor down and you will find the plug.

Each sensor has as part of the sensor a short pigtail.  Feel along with your hands.  You'll find the connector.  And using a bit of anti-seize during reinstallation is a must do. 

Sockets for those sensors are pretty common due to all the automotive application.  They're a bit long though so, depending on pipe routing, getting them off while still in the bike is likely a far more difficult option.  Once off the bike any good box end wrench should get the job done unless they've already seized up some.  That's not likely on such a new bike yet though.

Great help is what you can find on this site.

Thanks Duece!

Again thanks guys!

YES,,, make sure to use Antiseize and use Nickel Antiseize if you can find it. Napa carries it.

Everyone answered your questions before I got here, so I'll just pick up behind them.  Yes, they are somewhat fragile so don't bounce them off the concrete floor or adjust them with a hammer.  Not as fragile as a spark plug maybe, but still needs to be treated with a little respect.  As for removal, a little penetrating oil can help if you're changing them after many miles or a few years, but I wouldn't think it would be necessary on a new bike.  Try it dry first.

Chip, from what I have read here, don't be surprised if the rear O2 sensor connection plug is under the starter and you have to fish it from under the starter to disconnect (sometimes not easy).
As Don mentioned, once you have the pipes off, I would slide a box end wrench down the harness so you don't round the corners off of the sensor if they are really tight.
Let us know how you make out.

This is from a service bulletin that Harlie sent out to it's dealers

1-Use a hack saw [part #OU812-09] and cut the section of pipe that the sensor is threaded into.

2-Install pipe with sensor installed and insert pipe with sensor in an upward fashion [see figure 1-A]

3-Use easyout [part #OU82-09] and with instructions included with easyout, remove sensor from pipe.


See Chip...it's easy

and remember
