Title: Got stripped bolt =( Post by Mr.Orange on 08/21/12 at 22:32:06 Its the bottom header bolt. She's putt putt putting out where the bolt should be tight. Any suggestions? |

Title: Re: Got stripped bolt =( Post by justin_o_guy2 on 08/21/12 at 22:43:50 Well,, I suspect its the threads in the head that ya shed, but, if ya havent pulled the bolt to see,, ya otta,, Wouldnt it be great to see the bolt is wounded? If its the jug that buggered, you can put a thread repair kit in, or, if theres room in the flange for a slightly larger bolt, maybe tap that hole out to the next size up. Its metric now, IDK what the nearest, larger bolt is, but it mite not be a big jump to an SAE size. |

You could try a 5/16 bolt. It's about the same size as the stock M8 bolt. Or use a stud and put that in the head, for future muffler removals to take the stress of the already damaged threads in the head. |

Title: Re: Got stripped bolt =( Post by Mr.Orange on 08/22/12 at 15:44:23 i just happened to grab a 5/16 from work so will try that out |

Title: Re: Got stripped bolt =( Post by justin_o_guy2 on 08/22/12 at 18:23:04 Look at thread pitch. If its not gonna line up, mite wanna get a 5/16 tap. |

Title: Re: Got stripped bolt =( Post by Cavi Mike on 08/22/12 at 20:15:40 5/16 is smaller than 8mm, not larger. 5/16=.3125" 8mm=.3149" I also advise against running a mix of SAE and Metric hardware, they are not easily distiguished from one another even if you have a trained eye. You're either going to screw over the next guy that owns this bike or yourself. |

Title: Re: Got stripped bolt =( Post by ralfyguy on 08/23/12 at 11:14:00 5/16" is 7.9375mm. If you measure a 8mm bolt it will be a tad under 8mm. The 8mm has lower pitch, about 1,5 times less than standard 5/16. If you do it carefully enough, it will work. You basically cutting a new thread over the top of the old one. As his old one is already boogered up, there is not much to loose. The worst thing that can happen is that this attempt stripe out as well. Then he still can mess with a thread insert or such. I fixed the same thread size before like that on a different spot on the cylinder Head and it worked just great. Either use a 5/16 tap and tap about half way in and then use the bolt to finish up, or if you don’t have a tap, take a triangle file and file grooves in the front of the bolt like a tap has and put some lube on it, turn it in the whole one revolution at a time, backing all the way out after each time, put more lube on the bolt and repeat until you are all the way in. Just feel the material, don't force it too much. Then use a new bolt and tighten everything down without getting too rough with it. |

Title: Re: Got stripped bolt =( Post by Cavi Mike on 08/23/12 at 22:25:53 You don't make any sense. If a larger bolt already won't fit in the hole, a smaller one will be even more loose. You don't even need to do math here, it's called common sense. So no, it won't work. And pitch has NOTHING to do with diameter so there's no point in bringing it up. An M8x1.25 bolt is the same diameter as an M8x1.5 and a 5/16-18 bolt is the same as a 5/16-24. An M8 is larger than a 5/16. That's all there is to it. |

Title: Re: Got stripped bolt =( Post by justin_o_guy2 on 08/24/12 at 06:31:38 5/16 is smaller than 8mm, not larger. 5/16=.3125" 8mm=.3149" Ya cant stuff a stripped out , .3149 diameter hole with a .3125 diameter bolt.. either drill it & stick a repair kit in it to go back to 8 mm, or drill & tap to the next size, IF the threads run deeper in the head than the bolt is long, a longer bolt may save the day, But IM not bettin on that. |

Title: Re: Got stripped bolt =( Post by Dave on 08/24/12 at 07:35:41 I reallly think we need to start promoting the use of Never-Sieze on the exhaust bolts whenever someone puts the exhaust back on......and not to overtighten the 2 exhaust flange bolts. Doing this will help to prevent the broken and stripped studs that come up too often. Both of which are difficult and time consuming to repair. |

I've always used an anti-seize on exhaust bolts, and also sparkies. I also use a shorty 1/4" drive ratchet for tightening the exhaust flange bolts to the head, to help me not over do it. R.F. |

Title: Re: Got stripped bolt =( Post by Mr.Orange on 08/24/12 at 18:30:08 Got the 5/16 in there nice and snug. No leaks. Rode home and checked for tightness. Everything seems to be ok for now. |

Title: Re: Got stripped bolt =( Post by Cavi Mike on 08/24/12 at 19:29:32 Good for you. Don't forget to tell the next guy you have mis-matched bolts. |

Title: Re: Got stripped bolt =( Post by verslagen1 on 08/24/12 at 20:05:18 isn't that getting a little personal? |
|
Title: Re: Got stripped bolt =( Post by Cavi Mike on 08/24/12 at 21:24:08 I didn't intend to mean it that way but after re-reading it, maybe subconsciously I did. Either way, tell the next guy you've put mismatched bolts on the bike. Just because you made a mistake doesn't mean the next guy deserves to deal with it. It's not his fault you made a bad decision. |

Title: Re: Got stripped bolt =( Post by justin_o_guy2 on 08/24/12 at 21:30:26 Whats the diameter of the header bolt? I worked on cars in the 70's. It was a constant brain twist trying to decide if it was sae or metric. Id stuff the 5/16the in it & giggle my BUTT off. |

I'm glad I didn't make any sense, but even more glad that my suggestion worked for the man. The header bolt is 8mm. They usually actually measure a little less than 8mm, and so is a 5/16 bolt. If that metric thread in there isn't all the way tore out, meaning no thread left in there at all, then you still can try the 5/16. It isn't the greatest solution, but might work. What did the man have to loose? Is it better doing nothing and just run with just one bolt? If have done it before, and it worked and was a simple fix. Why was that suggestion so terrible? Anyway, I'm just happy for him it worked, and even if he sells the bike and the next owner messes about with that bolt, he will figure out that this one bolt is different. As soon as he puts a wrench to it, as the standard wrench for a 8mm bolt is actually 13mm, and Suzuki decided to make it 12mm. I don't recall the wrench size for a 5/16,but I think it was 1/2". I'm more used to metric sizes, because I have been a machinist in my native Germany since 1984. |

Title: Re: Got stripped bolt =( Post by justin_o_guy2 on 08/24/12 at 22:11:22 Actually, I think I was the first to recommend going with an SAE. I dont have a problem with it, at all. A problem solved is a problem solved, Who is to say it wont last? |

Seriously? How about the cylinder head? Is that big enough to "loose?" A longer 8mm bolt would have been the best option, not cross-threading a completely different bolt in. Just because you're an ignorant hack doesn't mean everyone else should be.

Title: Re: Got stripped bolt =( Post by justin_o_guy2 on 08/24/12 at 23:14:28 YOure the one advocating tossing someone out. A difference of opinion isnt worth that. How about stepping back & taking a deep breath? We are talking about someone with a problem & trying to get his bike back on the road using methods he can manage. I dont remember you suggesting a longer bolt. I think that was me, Im not upset that he went with the 5/16ths,, You seriously need to calm down, & if that means a few days of not coming here, okay,, but chill, man, its all gonna be okay.,.no ones gonna die, treason isnt being committed & no ones wife is runnin around with a Harley rider.. well,, heck,, I guess I cant really say that, but I can hope,, BUT, IF anyones wife IS runnin around with a Harley rider,.,Im pretty sure its yours,, See? anyone can get personal,, it doesnt prove much, does it? |

Title: Re: Got stripped bolt =( Post by Cavi Mike on 08/24/12 at 23:33:00 A difference of opinion? This isn't poetry, this isn't art and this isn't English class - this is math. There is only right and wrong. If you want to paint your bike bright pink, that's your choice. But if you want to cross-thread the wrong bolt into a hole? You are wrong. That's all there is to it. A square peg doesn't go in a round hole even if you get it to "fit." You are wrong. |

Title: Re: Got stripped bolt =( Post by justin_o_guy2 on 08/24/12 at 23:39:09 You may not agree with the method, but IF the result is a header that doesnt leak, It WORKED,, Feel free to maintain every level of purity in your solution of problems. Allow others to keep their ride on the road however they can, What mnakes you so sure he wont study the options & work on it this winter? Youre taking a lot for granted. You are happily very judgmental,& ready to punish a man for solving a problem in a manner that is beneath YOU,, dude,, back off.. |

Title: Re: Got stripped bolt =( Post by Mr.Orange on 08/25/12 at 08:50:22 I wasnt trying to start any gang wars here. The 5/16 fit snug, doesnt leak, and plus Im not planning on demonizing anyone on here for helping. If this is what I get for asking for help, Id just assume forget coming here any longer. |

Sir, it isn't your fault. I was trying to help you out with a simple inexpensive fix. The problem is the immaturity of a few strays you simply have anywhere you go. They are unavoidable and the best is just to ignore them. Please don't take it too personal as it isn't worth it. Please do stick around and ask away, that what this site is all about. |
