I installed a number of farkels, including a doughnut thats supposed to protect the front isolator mount from the shear loads that make them fail prematurely. Went for a ride today and it seemed like there was a lot more vibration with the thing installed then not. Does this make sense? |

It does if it prevents the isolator from doing its job. Pics would help but if its hard up against the metal bracket and bolt its pretty much a rigid mount. |

Premature failure? I recently replaced mine at 38,000 miles just in case...but it turned out that there was nothing wrong with my original one. |

According to an old post by Strada, if your mount has already failed the mount saver won't work, and will increase vibrations. Sounds like yours is toast. |

Try riding down the same bumpy road with/without the donut and compare. |

I did compare off/on thus the reason for this post. My bike has 5000 miles on it and the idolator mount still has the proper gap. Can it fail and still have the gap? With the bike at idle there is movement betweent the doughnut and the mount. |

Sorry for being obtuse. I've been using one for several thousand miles now and haven't noticed a difference. I will find a bumpy road in the next couple of days, test/check mine and post my findings. |

Mine failed at just under 6k - noticed a difference on the way back from Buelltoberfest and upon inspection big cracks and voids in the rubber. I think my bike was parked to close to Orangeulius' bike and it got infected.... |

Another.. This happened on a cross country trip two weeks ago. Had to call a dealer 500 miles ahead in Hays Kansas to have it overnighted to the dealer. Changed it in the lot, piece of cake.. |

They don't have to be that bad to be failed. The bolt gap can be normal and the rubber cracked to the point that it will cause vibes, as in on the way out. The one pictured above was probably bad for a couple thousand miles.
This one is cracked all of the way from each end nearly all of the way through the webbing, vibrations are noticeable when it is like this.
If your mount is like this and you install the rubber biscuit it will vibrate worse because when you accelerate the mount will be allowed to directly "lean" on the mount bolt. It has little to do with hitting bumps, the viberations are mostly noticeable under load accelerating or decelerating. You can feel it if going through a dip that will max out the mount from the weight of the engine also. (Message edited by etennuly on October 09, 2009) |

Only noticed the vibes under 3k rpm's. It caused my headlight filaments to touch blowing the fuse. That was how we found it, troubleshooting the headlight issue. |

Ok I think I know where the new vibration is coming from and it's not the front isolator. A close examination shows the rubber interior of the mount is fine. I had just as well, replaced a lost bolt on the front muffler clamp and I thought that both of the bushings were still there however upon a second look the right side bushing is missing. Any idea what I can put there. I'm going to bet my dealer won't have one in stock and I'm leaving on a big trip in less than a week (Message edited by paralegalpete on October 09, 2009) |
