Chris,
Has the ambient temps been cooler since you've gotten your bike back from the dealer?
I'm betting a barley-pop that the ECM or Bank Angle sensor is to blame. One of the two cant handle the heat under that much thicker seat.
HD called me too and wanted me to take the bike in to a dealer. Unfortunatly I dont have the free time to do so for another week. |

It has actually been hotter as of late. I am a bit perplexed. I hate to just let them start replacing parts. I am going to grease all the connectors this weekend. I have put about 200mi. since I got it back from the dealer and it has not died once. It was dieing 2-3 times on my 20mi. commute to work before taking it in. |

Mine happened at the end of a VERY hot day (95F). The bike ran flawlessly all day. It was only the ride home at 1am when the problem happened. It was *much* cooler at that time.
Also I was having problems with the brake light sticking on. I wiggled the wires to the rear brake light switch and "fixed" that..makes me wonder about the house |

Today it shut off for the 2nd time. Flicking the kill switch off then on and it fired right up on the move.

Flicking the kill switch off then on is the equivalent of resetting the ecm, again pointing to the cam position sensor or bank angle sensor or associated wiring, as pointed out in above posts. Those are the only 2 sensors I can think of that can kill spark and fuel while riding along. Except for the throttle position sensor, if it lost the plot the bike may think the throttle has gone down to idle while riding along, giving the impression of the bike shutting off, depending on which of the 3 wires let go. Could be the ecm too. I have an uneasy feeling that it's none of the above. |

Got mine back from the dealer after three days and was told they found nothing. They changed the ignition relay because he could. I asked again if they had contacted Buell Tech and they said they did not call but emailed them. I have not heard any thing from the dealer about a reply from Buell.

Over 1000 miles on since changing the bank angle and cam position sensors and no more engine dying. All types of riding involved. I'm very pleased. Thanks Buell, H-D tech and Harley-Davidson Sport Center in Duluth.

Is there a seperate crank posistion sensor as well?
The reason I ask is my tach, both times, has kept working.
I don't know their ECU strategy for engine posistion tracking, but some if they loose one signal, they loose sync. Maybe they can't get resynced? |

No CPS (crank). ECM may use the primary coil winding of a coil for rpm reading. I speculate that there will soon be a different sensor for engine rotation timing issues that does not require manual adjustment. |

Davo - just clearing this up a bit, there is a lot of different terminology that gets confusing between cam position sensors, crank sensors etc...
Buell uses a cam position sensor only (runs half crank speed, so the info from one revolution of the cam represents 2 revs of the crank). The graph below was recorded by Gunter from Germany, much thanks to him. TDC of the front cyl is "C", and TDC for the rear cylinder is "D". The uneven gaps between the 2 groups of 3 pulses from the CPS let the ecm know the whereabouts of the crankshaft.

Well it has been a week since I picked up my Uly up from the dealer. So far it has not stalled since I have picked it up. I called my dealer today to find out if they had gotten a reply from the email they say they sent buell. They said they have not gotten a reply. I am not sure if the dealer really sent an email or if Buell is not responding. So far I am not happy with the way the communication between the dealer, Buell and myself is going. So far leaving the dealer name and my phone # in a previous post above and calling Buell CS with the same information know one has spoken to anybody.

Well My Uly dies yesterday while crusing at 70mph, flipped the kill switch back and forth and it fired right up. I was able to move to the side of the highway while trying to get her fired up again, it was down to 40mph by then. I could see where this would be a big issue on a 3-4 lane freeway with tailgaters!
The question is what do I mention to my dealer as possible cause, bank angle sensor, cam position sensor, ignition switch, and/or ECM. Or all of the above? |

Well, all those could be the cause. However, I am of the opinion, at least in my case, it is water getting in somewhere causing the problem. Mine had got so bad I was afraid I would not make it home one day, cutting off several times in a row, it would usually only do it once or twice in trip. After taking it to the dealer and sitting in the dry for a week the problem has went away. My dealer had no idea and ordered a new ignition switch and kill switch to try. The parts have not been installed yet and course now I am reluctant to have them replaced. I am waiting to get caught in the rain to see if it happens again. |

Dry day, no water on the Uly yet, not even a wash. 85 degree weather 50 miles into the ride, this was actually the second time it has happened. I rode another 150 miles after with no problem?
Bike has 1100 miles on her as of yesterday. |

Yea, I don't know. It seems to be a guessing game at this point. Mine has just seemed to cure it's self. I don't know. |

Opto,
Thanks again. Sorry for getting back so late after your post. I have found something very interesting in the data you posted. I am looking at the minute difference between D3 and D1 pulse. There is no apparent difference in the D3 to D2 what we are looking at is the ECM offset of the spark timing from static to dynamic. If you have sheets at different rpm then we got the keys to the box! I read the rpm of this sheet to be right, it is at 1000 rpm. Do you have a blow up of this? I would like to measure the D3 to D2 difference in time and then compute degrees. |

Al,
Did you see the D3 leading D1 in Opto's post above? And then the next time around D3 was much further ahead.I measure about 13 more degrees and the engine is at the same rpm, 1000 rpm and always less than 1500 rpm. DO you know why the advance would jump 13 degrees? As discussed, the stock map does not reflect the command. If TPS had been pumped the rpm would have picked up. |

Thanks for the info Opto!
Mine never happened in the rain nor after a wash. Never when hot either. |

Hono,
Have you pulled any codes. Look for a 21. I had the same problem. It has not happened again for months!! |

Mine died 3 times on my 7800 km trip. Once in the middle of no where, once when I was expecting it and once I got it to quit for me. First time it quit I pulled over to the side of the road, the tack continued to work. Second time I was expecting it as the right turn signal indicator quit just like the first time and it died. I reached forward and turned the ignition off and the on again and she fired up. Third time I was riding and jiggled the wiring to the left of the steering bearings and i got it to quit. Turned the ignition off and then on and it fired up. Anybody else have or notice the signal light indicator not working? |

Thunderbox,
I've got the problem with the right signal light indicator not working intermittently, and I believe it's a wiring harness issue. It happened since day-1 with the bike, but I was never able to reproduce it when at the dealer, and they said they couldn't find anything wrong.
I now find that if the indicator is not working and I turn the bars (left) I can get it to work, and vice-versa. The severity of the problem also seems to be increasing, as I have now seen the same behavior (once so far) with the neutral indicator.
I've been off the bike for a couple of weeks due to work and weather, but plan on taking a look at the harness routing soon.
Are there any recommendations for changing the routing, or is it enough just to loosen the ties that hold it in place. Are there other steps that should be taken to repair this? |

Removed the face plate and check for wear spots on the harness. tape areas of high risk of wear. Then remove the plastic wire harness holder on the steering neck and with a file round of the sharp edge facing reward. put some extra tape on the wiring harness for protection and reinstall the plastic harness holder. If your horn rattles it would be a good time to secure it when you have the face plate off. The wiring harness is a weak link on the Uly. It takes a little TLC. |

Engine dying problem seems to be fixed as I mentioned in previous post, but the right turn signal indicator began acting strange last night for the first time. I had just washed the bike so I figured I'd take the switch housing apart later if I needed to. Then I read the 2 posts by thunderbox and Smcnamara. Hmmmm?

I need to make a correction on my above statement regarding calculations on the graph. I stated in my prior post that the graph which Opto posted, the rpm was 1000 and I now believe it to be 2000 rpm. I failed to double the number to represent crank speed. My calculation was cam cycle which is 1/2 to each crank cycle. This would better explain the advance which is represented by D3. |

Is there a real solution to this problem?
I have had it happen to me 3 times so far -- twice today in heavy freeway traffic and 80 degree heat. It hasn't rained for a while so it's not water causing a short.
What do I tell the dealer to fix? |

Has this problem been resolved? Mine has done it 3 times so far -- twice this weekend in 80 degree heat (and heavy traffic).
What do I ask the dealer to fix? |
