Exhaust bolt help

[inuyasha]

Hi
I surely hope you put a bit of the blue loctite on while installing them, as it should save you the hassle of them falling off once again

Take care and ride safely

I use red loctite for all aircooled engines. It's for higher temp applications

So then...I am the only one that uses the longer threaded rod connectors vice thinner nuts that can strip more easily?...just curious...

I ordered a few of these sets a while back to have on hand.

@ Hank: Yup, I used a generous amount of Loctite and just so people understand I doubled up leaving less chance of stripping, falling off etc.... You can literallty freeze your nuts off here lately, it's been a colder winter than we hoped for BUT I'm still riding, just harder starts in the morning

Double up the nuts is a great idea and works well. As for the cold...same here..it is actually so cold....you can SEE people fart...

I tend to use the 6mm stainless locking variety. Then like Sammy Squirrel, "You always know where your nuts are"

[jmstar09]

I've never had an issue using the standard nuts with split washers.

LOL
now THAT'S cold!!!

Correctly tourqued to spec the hardened steel nuts designed for exhaust flanges generally work best. Milder general purpose nuts will corrode faster and become more problematic over time.

I was thinking about drilling the acorn nuts and adding a bit of safety wire. loctite is nice but I use antisieze to help parts not corrode and be frozen when I do wish to disassemble them later.

[jmstar09]

How about we all just check the nuts once in a while? I have an '03 scooter with close to 9000 on it and the exhaust has never leaked because every 2-3 weeks I go over it and check/tighten any fasteners I can get at without taking it apart. Most guys and gals wait til there's a problem to start getting proactive. That's too late.

[scootercapecod]

The only reason in my mind that they fell off was because the cheap metal they use for mounting bolts contracted during cold weather. That said I agree that checking things every so often is a good idea. If I had thought to do that I might have prevented the issue all together. Seeing as the problem didn't make itself known until the thing fell off the manifold, I wasn't concerned but yes, I will check more often now that I know what the cause is.

These nuts need to be removed and re-installed about once a month.
This is to prevent rust from seizing them (oh yes, oh yes) and to ensure they don't work themselves loose.
Loc-tite will burn and may cause further seizure issues.

And if you don't want to replace the cylinder head, do NOT tighten them back up without a torque wrench!
