Central Maryland | Definitely a bitch to get cracked and loosened. I gave up for tonight; just have too many others things going on 'round here at the moment (like work).
Can't seem to get a 6 point 22mm on the rear one, and the front one won't budge. I need to heat the pipe (with the engine) and see if I can get the front to move... or it's penetrating oil time. I think I need to get a 12 point box wrench as well; there's just not enough room to get a 6 point wrench to bite.
You can look at them suckers and think it's easy to get to them but Ha ha ha ...it's a bitch; once you try to start putting a wrench on 'em.

Broken Arrow, OK | Sorry to hear that.
Mine were a piece O' cake. I do remember once I got the wrench on, I hit that sucker with a rubber mallet and they broke free easy.
The hardest part was getting to the zip ties on the front one to weave the wiring out. Keep at it!

Ya, I CUT those zip ties and then replaced them afterwards. I'll work on it again tomorrow; I need to buy a 12 pt box end wrench.. Somewhere. |

The Vic Shop - Central Iowa | It seems like they are either stuck or they come right out.
If they are stuck get ready for a fight. I've found the best way is heat and lube. Heat the pipe moderately, then if you can get them to turn a bit work them in and out while blasting with penetrating oil. Don't try to just loosen. Loosen as much as possible, lube then turn it back in. Do this a dozen times and it SHOULD eventually work its way out. Worst case is it totally strips the sensor and you'll have to retap the pipe. Best case is it'll free up with a bunch of back and forth. |

Central Maryland | Thanks Rylan. Hopefully when I find a 12 pt 22mm I'll be able to get success at least with the rear one. |

I use a 7/8" wrench. When they are really stuck a 7/8" deep socket and breaker bar, but that is always followed by having to tap out the pipe. |

Eeak gads! I do not want to have to tap the bung hole.... Rylan.. when you have done this; were you just chasing the interior threads with the tap. or actually cutting a new interior thread size? |

Ha! Ya... that sounds odd when you read it.....
But......
GOT 'ER DUN !!!!!
Used some penetrating oil on the sensors, let it sit for 2 hours while I raced around on my DR650 looking for a offset 22mm 12pt wrench (found it) and then was able to get a good bite on the rear sensor; she came off with no difficulty.
The front one... well the damned offset wrench couldn't get a bite on it... so I tool Rylan's advice and used a 7/8's open end wrench; and got it to break loose too! Nice that I didn't destroy the O2's... so if I ever have to retrofit them; it won't be an issue.
Now I can't find any copper anti-seize for the bung plugs... do ya'll think regular anti-seize is OK in this area of heat?

Central Maryland | I got the "Bung hole" plugs from Jon at Witchdoctor's. They're like $13.65 a piece.
The "Bung hole" plugs did not come with gaskets though... i was expecting metallic ones' like the ones you see on spark plugs (and the O2 sensors have the same type of spark plug gasket as well btw...)
I have some Red High Temp RTV Permatex gasket maker that I am going to use sparingly on the flange of the bung hole plugs to ensure an adequate seal; not so much that it would be an issue to break them loose if necessary.
Still in a quandary about using regular silver anti-seize on the threads of the bung plugs; or maybe a trip to Pep Boys tomorrow is in order for the copper anti-seize stuff.

Installed and running a Dobeck EFI jet Kit and Lloydz upper air filter. Need to disconnect and remove the O2's (removing O2's and plugging for a cleaner look on the head pipes) so that the O2's don't constantly fight the Dobeck's enriched fueling settings against what it's telling the ECU for stock map fueling at cruise.
Something like that.

Broken Arrow, OK | you really didn't miss anything, Jeff.
It's a personal preference. When we install fuel tuners like the Power Commander or Dobeck, etc, the factory exhaust sensors get disconnected.
Since they're no longer used, I just preferred removing them and installing plugs for a cleaner look. Doesn't hurt a thing to leave them unhooked and in place. |

I'm leaving this one alone! I was thinking of asking for clarification. it almost seemed like you were saying that Witchdoctor's nuts were small enough to fit the bunghole properly. But I'm not going to since it is beneath me. The comment, not the bung hole. Well, anyways, crap. Y'all are a hoot!
Thanks for the heads up on the parts, I think I'll get rid of my O2 sensors as well since they aren't being used!

I have not yet ruined the threads on the pipe - yet. If the sensor is stuck and you have to force it out then you'll need a tap to remove the softer metal of the sensor that is left behind.
In other words, if your shaft is stuck in the bung hole, a bit of lube and a bunch of tugging should get it out. Ream out the hole to clean it up. Then get some bung plugs and plug up that open hole so your exhaust gas doesn't get out. |

So, you're wanting to whack the bung hole? Or your saying there's a phone application to [determine the proper amount of] Vaseline used when screwing the nuts into the bung hole? Does it matter if you're off a little bit on the lube? |

Peru, IN | I just wanted to make it clear that willtill was the one who started the lubed up nuts in the bung hole discussion (post #7) although it's fairly obvious that, while he may be the lead freak, he's certainly not alone in his freakiness. There's lots of room in his freakdom. I'll bet Thanksgiving dinner is a hoot at your house, willtill. "Can you please pass the greased nuts, Grandma?" "How's your bung hole, Uncle Tim?" |

Central Maryland | In the first place... Ya gotta wonder who in the world ever gave the term; of the sensor hole in a head pipe; a "bung hole" Someone probably long ago derived that term for it after wrestling and cussing it out; in an attempt to work with it; and finally calling it an "asshole!" in frustration... and then someone else came along and termed down the phrase to the more politically correct term of a "bung hole".
Yes, that is my hypothesis on this. |

Peru, IN | bung-hole (n.)
also bunghole, "hole in a cask for a stopper," 1570s, from bung (n.) + hole (n.). Sense extended to "anus" by c.1600.
You're probably pretty close. Looks like it started out with wine casks. I wouldn't have guessed it would have a "darker and dirtier" (I can't stop) meaning by 1600. Figured that happened on Beavis and Butthead. (Cornholio says "I need TP for my bunghole!" |

I would, but it appears that I like to make things complex for myself. I finally found some Hi Temp Anti-Seize (the copper stuff) at West Marine (boat store) but forgot to take a plug with me to size it for a copper washer.
So instead of buying a plethora of different sized copper washers; I'l just use a fine bead of the read Permatex hi-temp gasket maker (sealant).
This will be a story someday for someone's grand kids... cause I ain't got none!
At any rate... this thread will certainly help others ...to watch out for that bung hole and it's inherent difficulties.  |
