I had no charging issues until after my reflash. Since the reflash, my battery light has been on, now unfortunately, my battery is dead. Help! |

Same thing happened to me. Within the first week after getting the reflash, and about 3 rides later, my battery was dead. I recharged it and haven't had any major issues. Although, My battery is never showing higher than 12.1 volts and as low as 11.7 volts. |

Hmmmmmmm, well, she's on the tender now, hopefully an overnight charge will help. |

Hmm. I think I've had the same problem. I just had my chip reflash at the dealer for the TPS issue. I rode all weekend, put the bike away. Went to take it out a week later and it's totally dead. I've had it on the tender since Thursday and after charging it, it seems to have a hard time holding that charge. I'm planning to bring it back to the dealer tomorrow. Any thoughts what I should ask them to check, beyond the standard stuff? |

For the record, I had the same issue--no charging issues for several months, since new; reflash; battery light on after reflash, battery dead overnight. I got a battery tender for it and plug it in each night. When I get home, the 'green' light (full charge) always comes on within minutes, telling me it hasn't discharged much, if any. From what I've read here, and my own experience, I think something occurs during the reflash that zaps the battery. At first, I thought it was because they leave the bike on without running while they reflash--but that doesn't seem to be it, based on the accounts of others who state their dealers leave the bike on a charger while the reflash process is taking place--and still have dead batteries within a short period of time, afterwards. Charge your battery up good and see if you continue to have issues. My guess--and it's only that--is after the initial dead battery instance, you'll be fine. Or rather, your battery will be. Or be safe and anal like me, and get a BT, too. |

Now you guys got me not wanting to get re flashed, how good did your bikes run with the re flash, I get a little surging in the low gears at very light throttle settings and does not bother me, I am afraid to get the bike re flashed and then my bike will be screwed up and running worse. Please let me know how your bikes performed before and after the re flash was done. Thanks Mike |

Loretta ran like shit for a thousand miles after the flash. About 300 miles ago, she wised-up and now runs like a striped ape. If the "learning process" was clear and quick there'd be no issue. Until BMC comes clean and TELLS US how to make it happen, I will not entertain another ECM flash. All is good with me and Loretta now tho. Z |

Delilah didn't take that long to learn. Even after the battery died once it was only maybe 100 miles before the surging went away again. I typically ride between 3k and 5k when just tooling around. With a wide mix of acceleration thrown in when safe. I noticed a couple things related to the drain I had. When the battery was low and until the battery tender got it caught up and turned green (only rode 3 times before I got it on the tender) the electrical system fluctuated voltage enough that I could see it in the dash and headlights. The last few days I've noticed after I shut the bike off about 30% of the time I'll hear a periodic whining every 20 seconds or so from the motor. It sounds like an electric motor from a pump or fan just starting to turn then cut off. I hear the sound when I turn the key on after it's cooled down and I first switch it on, but it also has the fuel pump running for a few seconds accompanying it. If I turn the key to on, let it go through the startup diagnostic and then shut it back off it usually stops the noise. If this went on indefinitely, I bet it could drain the battery pretty easy. Electric motors have a lot of draw at start-up and that's exactly what this sounds like. |

This is really interesting. Zac - do you keep Loretta on a tender? I have not had any starting problems post reflash - but the stutter between 3-4K RPM makes me crazy. Sounds like a good best practice is to keep the 1125R on a tender. |

I'm not "religious" about it, but I have the Tender lead handy at Loretta's spot and a 14" box fan in the garage. I usually run the fan at the front wheel and plug the Tender in when I get home from a ride, or work. Most of my riding for the last 1k miles has been commuting, with some mid-length "fun" rides thrown in. I cruise in the highest gear I can without chattering the tranny. That means 60+ for 6th for me. I have had a dead battery only once, right after the flash. I did run the battery down a couple of times, during break-in when I flooded her. Wish I'd known the flood-recovery method then. WFO, hold, key on 4 seconds, key off. Repeat once, then start as normal. Z |
