Hey, I have had speedo problems the past few weeks. Started out working intermittently, then just stopped working altogether. And i noticed its not counting the miles on the odometer either. I read past posts, and so I took out the speedo sensor and cleaned it off. There was a small amount of grey oil, which had metal on it (i took a magnet to the goo on my finger and it stuck to it). No huge chunks, thankfully. but its still not working. Any ideas? Its just shy of 10k miles now. Thanks! | ||

I can only be electrical and the sensors go bad. I'd start there. http://www.americansportbike.com/shoponline/ccp0-p rodshow/17165.html | ||

Yeah, what he said............ | ||

The sensor is interchangeable with HD. Take your's to a HD Dealer and pick one with a similiar cable length. I'm running one from a Dyna, but the cable is longer than it needs to be. (replaced at Sturgis -- 2007) | ||

"Speedo Sensor Problems The speedo died and the trip odometer still registers but does not change. It is not a fuse … it turned out to be the pick-up unit that is mounted on top of the transmission box. As you are sitting on the bike it is right-of-center. It has a large black wire, 1/2" x 1/2" black plastic piece and one allen bolt holding it in place just back of the starter. Make sure your plug wires are not chaffed at all. Also make sure that they are routed away from the wiring harness of the bike... the wires can cause stray voltage in the engine and destroy your speedo sensor. As a matter of fact, Buell recommends replacing your plug wires with your speedo sensor just to make sure. Get the updated sensor p/n 74431-01Y (the old number was 74402-95)." Found all that info here, http://www.saintjohn.nbcc.nb.ca/marriott/x1/, its a great site. if yours is doing exactly the same, i'd look into a new sensor. Nick | ||

I'm wondering if there is a problem with a batch of speed sensors. My original lasted some 70,000 kms (45,000 miles?), and when my speedo stopped working I bought a new one from Al at American Sport Bike. This one only did maybe 3000 miles and ceased to function again. I've just fitted a new one and we're back in business. I wonder if I got a faulty one. I'm going to Dremel the old one apart and have a look. Might even learn something. | ||

short history: Early sensors lacked a voltage regulator to protect the internal circuits from spikes later ones had this built in. | ||

It was beat to death back in 2001 when they started popping... 1) The hall effect sensor buried in the assembly is rated for a maximum voltage just barely higher then what a happy Buell normally creates. Marginally unhappy Buells that otherwise run fine will often exceed it. So a bike that ate one sensor, will often eat more. 2) The mechanical packaging of the sensor had issues with breaking wires. 3) We have dozens (literally) of cases of "serial sensor offenders" being fixed once and for all with the addition of a 5v regulator to the sensor power lead. 4) We have at least one case where someone hooked up an o-scope to an offending bike, and was seeing significant very short but high transient voltage spikes hitting the un-filtered sensors. Just the sort of spikes you would want to send if you were trying to kill a FET type device buried in a hall effect sensor. For what that's worth... somebody did source a replacement sensor from Newark or something that could be packaged back in the old assembly, but it's a *very* non trivial mechanical exercise to dig out the old potted one, and put in a new one. I have a schematic posted for a simple 5v regulator / filter for protecting the old problematic sensors. It really only made sense in cases where you had a bike killing sensors before Buell had the fixed part out. It got old replacing them at $50 a pop (I have two carcasses in my parts bin). Now that the new Buell parts are fixed, all you have to do to fix the problem is replace the part. | ||

"3) We have dozens (literally) of cases of "serial sensor offenders" being fixed once and for all with the addition of a 5v regulator to the sensor power lead." Yes, I am one of those cases. There is a new sensor out, but I'm still running an old sensor with the 5v regulator that Reep designed and posted a few years go. I believe this was one of the times Buell made a product improvement based on postings from this board. I suppose it could be a coincidence. | ||

So now as an owner of a 2000 X1, my question is when did they change over to the good stuff? I think I keep getting the short end of the stick with my production date being Nov '99. Looks like most of the good stuff came in mid-2000 production cycle. | ||

The updated sensor actually came out AFTER they discontinued the tubers. The first production Buell to get a fix was the XB12, and it didn't have a different sensor, it simply fed the sensor 5v from the ECM instead of giving it full battery voltage. The updated sensor is for 9s and tubers and has a built in 5v regulator. | ||

All good, but the one that lasted 70 odd thousand kms was the original and the one that died was the updated one. ? |
