Today I was getting ready to go to work, started the bike and then smelled smoke before I could shut the motor off it quit. I look down and see smoke everywhere, it smells electrical. I put the bike away and get in my pickup and go to work, try not to think about what happened to my bike to much as the day slowly passes by. On my way home I stop and fill up my pickup after $70 in gas I head home. This $3 a gallon gas sucks. I get home find out that the ignition fuse has been blown, I replace it and turn the key on nothing happens no lose of power, then I flip the fuel pump switch and the fuse pops again. My brother though he saw some smoke coming from around the front sprocket. We do it again and he definately sees smoke coming from that area. My neigbor comes over and we do it again this time he seen where the problem is, the speed sensor is smoking. We disconnect the sensor and the bike runs like new again. Glad to find out that it wasn't anything to major just a failed speed sensor. But I still have some concern, I have heard of speed sensors failing but never so dramaticly. The only thing I can think of that happened was there was faulty insulation between the power and ground in the sensor. Has anyone ever had a speed sensor smoke really bad when it decided to die? | ||

My speed sensor just went out last Friday, not in a dramatic smoking sense as yours did. Mine went out without having any indication of trouble and I was doing twisties at the time and was left stranded. Once I got it home I unplugged the sensor just as you did and the bike would start and run without blowing the ignition fuse. I rode over to the local Harley/Buell dealer and picked up a new sensor, came home did a quick r&r and everything was back to normal. The new sensor has a nice service loop with a clip that positions the wires instead of the wire being so tightly bent over the top of the sensor like the old one did. | ||

There were two failure modes known (at least). One was just a nice friendly blown semiconductor, the other were shorts or broken insulation on the wire. Sounds like you got the latter! |
