When I left the house this morning I noticed some severe high frequency buzzing in the footpegs (more than normal). I saw that I needed gas, so stopped after riding about 2 miles to fill up. When I took off again on the same rode, same speeds, same riding conditions there was no more buzz (at all). So, does a full gas tank vs. an empty one have any effect on vibrations? I don't see how it would, and am not claiming that it does...just an unexpected observation that I'm quite sure was not just my imagination. Try it before you knock it. Any thoughts though? |

I would think a frame full of fuel would have a damping effect on vibrations. |

I would imagine that gasoline has a vibration damping effect. Since the foot pegs are attached to the frame, it would seem logical that a full tank would allow less vibration transmission than an empty one. |

Damn fast typer. Get a life. After seeing you ride at Buelltoberfest, it's nice that I can be faster at something. |

Another thing to think of: Cold affects the various rubber thingies that hold the engine in the frame. On a cold day, my X1 will shake the crap out of me for about 20 minutes. Perhaps the engine heat got to your isolators while you were standing still pumping gas? |

Definitley has a damping effect. Another example is older Bourget custom bikes with standard frames compared to the later ones with 3 1/2 quarts of 20w-50 oil circulating through the frames. The oil in the frame bikes are noticeably smoother. |

I have the opposite effect on my Uly. Full frame of gasoline and I get vibrations. After about 60-70 miles, they go away. I don't feel these in the pegs, but more on my legs through the frame. Been that way since my bike was new. Chris |

I have had that kind of issue before and found an odd sort of answer. I sat on the seat crooked and partially pinched a nerve in my lower back. I didn't realize it until I got off the bike, but I felt all manor of vibration and weirdness until I stopped and remounted. But hey, I'm old and feeble and have had back surgery before. |

Sometimes the vibrations are from the burrito platter. |

Sometimes the vibrations are from the burrito platter. Yeah, but the source of those are usually more obvious.(and frequently needing immediate clean up attention) |

It could have been the fuel pump buzzing. My BMW would do that if I ran it out of gas. |
