The rear one is mounted in a fashion that it would be hard to wear it out or have the rubber break. Might want to have one for five years down the road for when the rubber rots though, but then the spare won't be so fresh either. May want to vacuum seal it and hide it in the dark. |

The rear one is a LOT harder to change too. We had to replace one on U4euh's XB9S at March Badness II after he had an "incident" trying to stay up with Erik on a spirited ride up 129. Metal part of isolator at the case broke off at the bolts- he rode it back to TWO ~10 miles without realizing it. With ~10 Badwebbers working and plenty of tools, it probably took 6 hours to remove one off of one of Stone Mountain's test ride bikes and install it on U4euh's bike. Easiest way to do it is probably to pull the frame off the engine, replace isolator, and reinstall. |

Etennuly - People install NOS isolastic (i.e. rubber) mounts on Norton Commando's that seem no worse for wear after 30 years on the shelf... Cheers, - HJ |

Thanks. I agree airless and sunlight-free storage on rubber. Does work. So a guy should have both mounts stashed at some point it appears. I need a bigger allowance! Pre-buying is hard on it. |

has anybody tried to rebuild the mount with one of these? It might have a little more vibration since it's made of polyurethane, but the mount is designed that the weight of the engine "falls down" onto the bolt, so it would not be driving the bushing out. If someone has an old mount laying around they want to send me I could try to find the bushing. Or we can wait until mine needs one (it already feels like your riding over an open grate bridge while braking at slow speeds, so I guess it already needs one ) |

I think using Poly there would be like rigid-mounting the engine. The front isolator has three "ribs" that allow the central core (and therefore the front of the engine) quite a bit of movement. If the supply runs out somebody will figure out a way to rebuild the old ones. |

It is odd we can't just stick a new rubber in there...instead of new metal too. |

The rubber is bonded to the metal. Somebody could probably figure a way to clean all the old rubber out, hold the center in the correct position, and mold a new rubber piece in place. If I had to replace one at this point I don't think I'd throw the old one away. |

What does Palmer do to add longevity to the item? |
