Be sure to come back, and let us know if that cures the problem.

Re:The great fuel injected Roadie 4 Years, 6 Months ago  
I pulled my rear O2 sensor and cleaned it with sensor cleaner, then ran some bristley pipe cleaners through the holes and then used a scotch brite pad to make the whole thing look new. The sheilding of the wires, not the actual wires was damaged, so I'm giving it one more try.
I replaced the fouled plugs with a fresh set and went for a 25 mile ride. It didn't act up last night, but I'm going on a 125 mile ride in a few minutes. If it acts up again, I'll order the Bosch O2 sensor and just go that way. I'll post results.

Re:The great fuel injected Roadie 4 Years, 6 Months ago  
While the wind is still fresh in my hair, and the ride is still fresh in my head...

I rode the 60 miles to my house, in typical 17 MPH winds with gusts of 25 MPH. I feel when I'm riding against the Kansas wind with my 225+ Lb. bod & a windshield, the bike is under a typical load.

My bike is running better than when I bought it!!!

Here goes, I tested 4th @ 55-65, OK. I tried 5th gear at 55-65, still OK. I was surprised because in the 2 months of owning this bike, if I tried 5th at anything under 62 MPH it would cough, bark & then run crappy for a few seconds after shifting back into 4th. I'm comfortable riding these 55 MPH backroads at 57-62 MPH, and not worry about getting pulled over. Those speeds in 5th, until today, was un-ridable, and riding the backroads in 4th gear ain't happening!

When I cleaned my O2 sensors the first time, I didn't unplug them from the bike. I've owned the bike 2 months and I've never had the battery disconnected from the bike, although I have had the battery tender on it twice.
Now for a couple of questions for those in the know.
Q: When I disconnected the O2 sensor from the bike, does the ECU sense a device being removed & replaced? (like a mouse on a computer)
Q: Does the ECU start reading the O2 sensor as "Fresh" or "New" after reconnection?
Q: Would temporarily disconnecting the battery reset anything?
Q: Should I disconnect my battery when I work on these things?

I realize I've only gone 60 miles, but I'm heading back "the long way" in a few minutes. That trip will involve some cool Kansas evening air. If it's gonna start fouling, then will be the time.

As Arnold Sez - I'll be back Gadget

Re:The great fuel injected Roadie 4 Years, 6 Months ago  
Made it back to my shop in Mac. Total trip 148 Miles.
The trip back was great. When the sensor is clean & operating properly, the gears seem to be longer, so I wasn't dogging when I shifted up a gear. I was shifting out of 3rd at 50+ & 4th a an easy 65, 5th gear was ready to go.
Then, at 130 miles, I left a stop sign, was gradually accelerating,3rd up to 50ish, 4th got up to 55, coughed, sputtered and as I tried to accelerate through it, she coughed a couple more times. My air intake sounded like a 4 barrell when I try to accelerate. The bike felt like someone had thrown a wet blanket over her. I eased her back the last 18 miles, she ran a steady 65 MPH, smooth, but labored, like... FOULED PLUGS!! or possibly the dreaded SVS!!

When she cools off, or tomorrow morning, I'll pull the plugs & O2 sensor. I'll take pics and post them.

Answers to questions:

1. No
2. ECU doesn't know the difference.
3. Other than codes in memory no.
4. Replacing an O2 sensor doesn't require disconnecting the battery, just make sure the ignition is off.

I've never heard of O2 sensor cleaner, anything like that would probably just ruin it.

An exhaust leak upstream of the o2 sensor can cause the sensor to detect a lean condition and keep cramming fuel in????

Re:The great fuel injected Roadie 4 Years, 6 Months ago  
Here are the results from last night. Could I be suffering form SVS?

The black on the plug threads is anti sieze, not carbon fouling.

Can't see any results. As far as SVS, doubtful.

No SVS - That is GREAT NEWS!!

The plugs and Sensor are completely covered with carbon soot, bike ran great until then.
I'm using Mass Air flow sensor cleaner, and a sctch brite pad.

The only thing upstream from the O2 Sensor is the Exhaust manifold, I checked those bolts, they are plenty tight.

why isn't the system throwing up an O2 error?
