I have replaced speed sensor twice due to no speedometer readings @ 3500mi. and 5500 mi. Now with 8000mi. I started engine and smelled wires burning. I shut bike off and removed probe from transmission. It was swelled slightly and burnt. I replaced it with one of the old ones. Bike runs fine but of course no speedometer reading. Before I buy a new sensor, what should I check? |

When was your last replacement? The new kit, (which came out in 2003 or something?) solved a long standing problem of bikes that like to eat them. |

The one that just fried had the date 04/22/04 on the bag- The one before I'm not sure. I did try cleaning all the ones prior to the fried one.

Definitely Townsend. Much nicer / wife friendly "resort" like cabins. The commute from there to the gap is a very pretty / relaxed road, and it gives you a "back door" to get into pigeon forge if you want a bigger restaurant or something.
The loop will make you go across the Cherhohola, then turn right around and come back across it, but that's not by any means a bad thing.
If you have two days, and if "wheels through time" is still in Maggie Valley, that would be a nice destination as well.
Come to think of it, Maggie Valley might not be a bad place to stay either. It's "further", but its all fast interstate, so if you are trailering the bike, it'll go fast. That might be a better launching point for the gap, the Cherohola, and the blue ridge parkeway. The parkway would be a nice "first ride" with a passenger, its slow, relaxed, lots of restrooms and rest areas, and jaw droppingly beautiful. |

Doh! Wrong thread... Too
2004 was close... I don't remember what year they changed... it was around then, because it was after the firebolt, around the time the lightning came around.
Got a part number? I think the bullitin here somewhere has the "new" number, or you could ask your dealer. |

Part # 74402-95B is on the bag of the old one as well as the new one just picked up. I read other riders problems with speed sensor, but none with them burning. I talked with tech. @ Harley shop @ he wanted to hook-up bike to diagnostic machine for $32.00. I did'nt know 2001M2Cyclone had a port. I'm tempted to just replace sensor and hope for the best. |

Any symptoms of any kind of charging problems with the bike? Like bad battery or a loose ground? |

Battery replaced about 3 years ago. I trickle charge about once a month if I don't ride that month. I will go check cables but it cranks right up every time. |

Then I would chalk that one up to a fluke and put in the new one. You could put a cheap voltage monitor on the bike to play it safe if you want, it's useful for the one time your stator dies.
Normally, when the old ones blew, they didn't smoke or burn up, they just stopped working, so this sounds like an unusual failure mode.
You could also cobble together a 5v regulator to protect the part... I did that on my M2 before the real fix was out, and posted schematics here you can search for. An easy enough build, and you can just hack up a cell phone charger if you don't want to build from scratch, but maybe not worth the trouble unless you bake another sensor. |

I think I will just replace the sensor and see how long it last, but what about what the tech. said about the diagnostic test. Is there a chip or something on the model bike? |

There is an ecm of some sort on an M2... I think it retards spark or something, not really sure what. I don't know if it will tell you anything useful as I don't know what all it can do... |

Bike is fine now- I did find positive battery cable to be loose. Thanks for help! |

Great! If it dies again, let us know, there are more aggressive options (that shouldn't be necessary)... |
