Hey guys, I have a 2009 1125R that I just traded a Sportster for. I love the bike but I'm getting bummed and frustrated. It has left me stranded several times this week. When it isles I can watch the voltage drop on the display. But at speed it charges.... When it drops to around 11.7 volts the check engine light comes on. When I speed the engine RPM up the bike starts to charge and the check engine light goes off. Last night I shut it off at 12.1 volts and tried to start it about half an hour later to no avail. I had to get a jump to ride back home. It only seems to.do.this after short distances. Is this normal? |

I forgot to mention that I put in a new battery on Monday. |

Sounds like the 2009 Charging system failure, needing a New Stator and or rotor perhaps even a Voltage Reg. all 3 someone will chime in with more info for ya... But 09 was a year that were known for these plms. |

It is likely the stator has failed, it is a weak spot on the 2009/2010 1125 models. The stator is what keeps the battery charged, if it is not outputting enough voltage, the bike will eventually stall. If the 2009/10 1125 is ridden at low RPMs constantly, it does not get sufficient oil cooling for the stator, eventually resulting it it failing.
Good news is, there is a permanent fix, Erik Buell Racing does a modification to the rotor cup, which allows it to provide proper oil cooling to the stator at all RPMs. The modified rotor plus a rewound stator permanently fixes the issue.
You can read more about it on the 1125 Board

Maybe the bike has the "Harley Fix" that involves the relay that open-circuits 1/3 of the 3-phase charging circuit at lower revs resulting in little or no charging below approx 3 grand but charging above that point. And if it does have the relay, the relay could be burned out and needing replacement.
Even so, that is a temporary solution and the proper course of action is to go with the posters above if the stator proves to be failed. |

Thanks guys!!!! Got it fixed. It was the stator issue and Iwent ahead and had the OEM parts put back in it because when I bought the bike I also got a two year warranty. I've looked into the permanent fix and it looks like it's something I will probably do once the bike is out of warranty. I tried to get them to do the permanent fix for me but sadly they will only put in OEM parts. |

Now that it's running and charging I've noticed something new. When I turn it off after running, the cooling fan continues for a few moments.... That's all well and good I know. But after it shuts down I hear a slight beep and what sounds like a pump running. It cycles off and on for awhile..... Last night when I put it in the garage was the first I'd heard it. It continued for several minutes before I went in for the night I didn't hear it stop and didn't have an opportunity to check it out this morning. Any ideas??!? |

The noise you hear after shutting off is the fuel pump cycling on and off for a short while. This is done, I believe, to keep the fuel rail pressurized which can prevent vapor lock and hard hot restarting. It's normal. Don't worry about it. |

Yep that is the fuel pump doing its thing, it will do it for up to 10 minutes. Go on a group ride with other Buellers and stop somewhere for lunch, once the fans stop it sounds like some kind of droid convention

Hello again guys. I have another question for you awesomely brilliant buell enthusiasts! At about 4500 RPMs I hear a sound that almost sounds like the cooling fan has something in the blades..... But only when riding. In neutral at 4500 RPMs it doesn't do it. |

What cleaner do you guys recommend for the hero blue rims on the 1125R? |

Tommy did you figure out what the noise was?
As for the wheels, I use S100 wheel cleaner, works fantastic. |
