I replaced the heads on my 2000 M2 last year. In my current fog, I cannot remember whether I used new front engine mount bolts (the ones that bolt into the aluminum bracket and the front head) or put in new ones. To be on the safe side, I bought some new ones to put in. My question is, can I replace these by switching them out one at a time, or is there some more complicated procedure for doing this? I figure if I leave one in, it will hold everything in place while I switch out the other one. I have a service manual but haven't cracked it open for this yet. I don't want to introduce any stresses to the assembly by not doing it correctly. Any expert advice would be truly appreciated. |

Crack open the service manual, and do a search in the knowledge vault here for any updated procedure. I, personally, wouldn't rely on one bolt holding everything in place while replacing the other bolt. Roadside repair, maybe, but not in a garage. |

Not an expert, but just thinking, it might not be improving anything to take them out again and replace them, just because. Might as well wait until some other service is being done that requires it? |

If it aint' broke. What Mike says, as usual is excellent advise. If you proceed, you'll need to support the weight of the engine in front. If you loosen/remove one bolt and if the engine isn't supported to prevent it from dropping, then the engine and bracket may shift so that it could be impossible to install the new bolt. Then you'd have to jack/support the front of the engine anyway. |

Sorry to leave that out - I had planned to support the engine from below as well. I just don't know if I should remove the bracket entirely from the bike, install it with the new bolts onto the head, and then connect it to the bike, or if I can get away with switching the bolts one at a time while leaving the bracket attached to the bike. The service manual doesn't have a procedure for replacing the bolts, it is just one part of a larger procedure. As far as leaving them on until something else needs work, it is my understanding that these bolts can only be torqued one time, and that they cannot be re-used. I don't want one (or both) of them to snap when I'm in a high speed sweeper! |

Service Bulletins & Manuals general section in the KV Service Bulletins I can't seem to be able to find the newest updated front engine mount procedure. I thought someone had uploaded a .pdf of it once, or else they just posted it in text format in a thread somewhere. |

Not real new, but it's something: B018 FRONT ISOLATOR MOUNT SYSTEM |

I thought there was an updated procedure, but maybe not. Maybe this is the one that supersedes what's printed in my service manual. |

Thanks guys - looks like I'll be taking off the front isolator to do this right. |

You've also got some good local people down there who could probably lend a hand. |

I've had it off before when I was putting new cams and pistons in, so I think I'll be alright. It was never an issue of not being able to do it, I was just looking for the easy way out. But thanks again. |
