I stripped this bolt hole, naturally, and the bolt vibrated its way out. Now it weeps. Can anyone recommend a fix and/or know the size of the missing bolt? |

No biggie, slap in a heli-coil. I think that's an SAE bolt, not a metric one, and I forget the size. Take out one of the surviving screws, go over to the nut section to find which fits, use that to know what size replacement screw to get, and get the right heli-coil kit. Auto parts stores typically have better selections of heli-coils and sell them cheaper. A hardware store is likely to have both heli-coils and bolts. It's up to you if it's worth driving several places to save $5 on the heli-coil kit. |

there's someone here who has the whole kit to the heli-coil alternative(can't remember what they're called) that we've been lending out. Can't remember who it is, thought it was bike_pilot or someone like that. Anyone noticing a theme here??It's a nice kit, used it myself. |

oh forget it. I'm thinking of the drain plug getting stripped. Brain fart. |

Thx for the info, guys. Heli-coil it is. |

A Timesert http://www.timesert.com/ is a better repair. More money than a Helicoil but more permanent. |

When I looked at the part that the bolt screws into, that is stripped, their is not a lot of material there and was curious if a heli-coil would actually work. Keep us posted on how it goes. I might need to do this in the future. |

I've helicoiled them, it works well. The timesert may very well be better than the helicoil. I don't have first hand experience. Either one of them is going to be better than the original tapped aluminum threads. Avoid drilling all the way through the cover. The holes do not go all the way through, and you don't want to make them go all the way through. |

If I remember rightly, I have not fitted one for over 30 years, you use the provided thread tap so you can fit the Heli-Coil. Given that you will get some swarf you may be better taking off the cover to do it if the hole goes through into the case. You do not want metal in your oil. Threads seem easy to strip on these bikes. I did one one a hanger bolt and I was using a brand new torque wrench as well? They are not hard to do but if you have not done one before just take your time over it. Good luck. |

"Avoid drilling all the way through the cover. The holes do not go all the way through, and you don't want to make them go all the way through." Yes thats good. Thanks. |

Thx, guys. I have recent experience with a heli-coil. I butchered my oil drain plug hole last summer. Heli-coil is in there now. Don't ask... |

For anyone who wanted to know, the Heli-coil was an easy fix. Just had to be careful not to drill all the way though the metal, and trim down the coil, as it was too long for the application. Solid now. |
