I don't think I did anything really out of the ordinary to cause a problem? I parked it in the garage the other night and plugged in the Battery tender? I did also washed the under carriage after changing the oil? Can anyone tell me if there are any known pick-up issues? or anything to get me pointed in the right direction? any help would be appreciated.

I see you have an 03, First thing I would do is remove the speed sensor, clean the junk off it and reinstall and see if that fixes it. They have been know to get funk on them and give a false reading.

Xbeekr... you didn't actually describe the symptoms but I'll bet it goes like this: Key On, the Tach and Speedo Needles do the obligatory "sweep", but once you're underway there's no speedo needle movement and the odometer is not recording any mileage either. Sound about right? Yeah you can check all the connectors and wiring like I did in the vain hope that it'll be something like that, but chances are if you've cleaned all the metallic-mung off the sensor (part of the sensor is magnetic) and it still doesn't work, the sensor is shot. Give Al at American Sport Bike a call/email and he'll set you up.

Been there, done all that.

Two Torx screws for the chin fairing, gives you enough room to remove the sprocket cover.

Three Torx screws for the sprocket cover.

TAKE A PICTURE OF THE WIRING SNAKE PIT.

One allen bolt for the speedo.

Pretty straightforward, really.

knowledge vault is full of info on this, look at posts from 2004 for the best info.

The short story is that the sensor is not a 5v type and when the signal gets dirty like the (+) back feeding since it is the same as the coil pack, the sensor gets fried.

Y0199.K Buell Speed sensor retrofit kit.
Kit includes new sensor, new connectors, and wire needed for update.

I took the kit and threw out the instructions and instead T'd off the cam sensor 5v source, since its right at the sensor, and got all the wiring to fit behind the cover. That is a real trick.

If you need any help PM me and I'll see if I can find the diagram I made.

Crashcourse411: somehow you made it sound more complicated than it really is. My '03 9R just got the one piece assembly, no instructions, no extra wires, or extra connectors. It really was bad one out, good one in.

The only cutting was some zipties, Get a pack of those. I'll agree on the wiring behind the cover. It's a bit of a challenge but it's not like the Italian bikes, it's doable.

True! the new sensor will handle the old source of 12v incoming to the sensor, and outputting the 0-5v to the speedo for the pickup. But the real fix for the issue is to get 5v regulated by the ECM to the sensor. THe ECM 5v is a clean source that should not spike and cause a premature failure of the sensor. Easiest place to get the 5v source is the cam sensor connector which is very near the speedo connector. '04 and later models had the 5v source right from the factory.

The ECM only understands 5v DC inputs so most sensors on the '03 bikes are 5v except for the speedo, and I believe the neutral switch. For what ever reason early bikes source the input voltage for the speedo sensor from the coil pack. The cam, TPS, MAP, and IAT are all 5v.

There were some guys on BW making and selling 5v regulators from Radio Shack as the upgrade before Buell had a retro kit available. It was also a cheaper alt. since Buell I believe wants $70 for the kit or like $50 for the sensor alone.

I tried the sensor only swap on a friends bike and he made it another 500 miles before it went kaput. At least his first one went 8000. His first attempt was to clean the crap off of it and that made about 100 miles. He then opted for the sensor alone. figured he would save some $$$. When that one went we looked at the service manual and found what was "burning" these things up.

Shortly after that mine went south and I accused him of swapping parts while I was at work. While we were both out of commission this time we took a deeper dive into the root cause and found the voltage issue and installed the full kit on my bike. Then he followed suit, and we have not had an issue since.

Well, there you go. Now you have a choice: plug and play or plug, fabricate and play.

My stock replacement has been good for about 2000 kilometres.

So! Do you think the battery tender caused a spike? Fryin the sensor? It is the only thing that I had done different with the bike since I have owned it. I have only owned it for couple of weeks now. I basically spent the day on monday cleanin her up and givin some love? Changed the oil ( motor and tranny) cleaned and put it on the tender! What gives ? I also noticed that it seems to be running really rich all of the sudden? Any link? Stumbling when it's warm, pipes are hotter? I don't know maybe I'm losin my mind?

From all I've read here, it seems that they just die randomly.

Mine worked on the way out, stopped at the dealer, wasn't working on the way home.

Might be good for the mods, or whoever does that kind of thing, to chart model and mileage of failure along with possible links. Buell might work with the date.

Hard to tell with mine as I'm the third owner. Previous owner never mentioned that repair, he was upfront with other repairs, no problem, but somebody had been under that sprocket cover before.
