Now that the weather is getting a little cooler, I have noticed that I have a vibration as I accelerate through 4000-4500 rpms. It is not gear specific. I noticed it after I had not ridden the bike for about a week and the weather was in the low 40s. I didn't notice it as much yesterday as it was in the low 80's here yesterday. There is no loss of power and it doesn't run rough, I just feel a vibration through the seat of the pants and through the handle bars and pegs. At 4500+ it smooths out and it is smooth up to 4000. Has anyone else noticed this? Is it temperature related, frequency of ride related, or do I have some sort of mechanical problem coming up? I'm coming up on my 5000 mile service, and I am going to have the TPS reset and timing checked. I am considering of replacing the spark plugs as well. Thanks. |

Deja vu? Check exhaust tract fasteners and components including header nuts, and check primary chain adjustment. A Buell is very good at telling you when something needs adjusting or is getting loose in the exhaust tract. |

My XB12Ss also had vibration at 4000-4500 rpm which was due to the primary chain too tight. The chain when checked cold was within the 3/8-1/2 inch range specified in the service manual, but when set 1/2-5/8 inch the vibration went away. |

I have the bike at the dealer to have the primary chain adjusted. We'll see what happens. |

I noticed the exact same thing today so I got on here to see what it might be. Did you ever get this figured out? Was it the primary chain? Too tight? That would make sense I suppose with the colder weather. Sorry to pull up such an old post. |
