Low end sputter, hesitation

Yup, just pop off the side cover, unplug the o2 and put this in its place. But to put the plug in the exhaust will require removeing the headers to get the o2 out, so I'll do that at a later time.

Plug & Play installation ?

Yes, very simple. I was happy with the results, being cheap and easy usually doesn't get you much.

Thanks for the info. Just ordered one.

So glad this worked for you! As far as removing the actual O2 sensor, I'll probably never do it. You either have to pull the headers or buy a special wrench (from Koken, $35, see here: http://cb1100forum.com/forum/showthread.php?tid=1779 )

Plus, it seems like the way to maintain value of a bike is keep it as stock as possible -- with this mod, it takes 5 minutes to pull the O2 eliminator from under the side cover and re-attach the stock O2 cable.

On the other hand, I get that people love the feeling of removing stuff from their bike. Some people like to add farkles, some of us like to strip things we find unnecessary. I get it, and I'm more like the latter. Sometimes, I feel like I've bought a used bike in part to rescue it from it's horrible modifications. Peter Egan wrote about buying a bike, then riding it around the corner to carefully remove the iron cross decals that were all over the thing. That's when a want ad becomes a ransom note.

Well said.

In my typical fashion I ordered an O2 Sensor Eliminator plug, AND THEN did some interweb research. Now I'm concerned about installing it.

I found a single reference on the interweb about potential damage to the O2 Lambda Sensor if it is bypassed/disconnected but not removed from the exhaust. Apparently the sensor normally gets preheated in order to produce proper readings before the exhaust gets fully warmed up. The thread author stated that the disconnected (but not removed) sensor would eventually foul and would not work properly if ever reconnected.

Is this a valid concern? Wouldn't a fully warmed up exhaust be hot enough to burn off any residue on the sensor membrane?

Someone, please, put my fears to rest!

If you google o2 sensor operation the theory explanations address just that. One said the reason they went to heated sensors was that the ones heated by the exhaust tooki a while to warm up and would foul up and other not good things (can't remember it all).

So, does that mean the sensors permanently fouled or just initially when warming up, enough to cause poor readings.

Will installing the O2 Sensor Eliminator Plug permanently damage the Sensor if I leave it in the exhaust?

Whether connected or not would seem to me of little difference. I intend to leave it in place. I cannot understand how having it disconnected would cause the sensor to fail.

Well, I don't either! The little bit of current that it would receive while connected would not seem to be enough to burn off any serious fouling. I would then expect that as the exhaust heats up, it would remove any fouling that might have accumulated while the bike was warming up.

In their video the Power Commander people don't say that the O2 Sensor needs to be removed after installing their Optimizer (Bypass) Plug.

However, I just don't want to risk the Sensor in case I ever have to remove the
bypass plug or if the resistors in the plug fail (they apparently can get quite hot to the touch).

Has anyone used a Bypass Plug for any period of time and then removed it? Did the Sensor still work or did it throw an EFI Code indicating that it had failed?
