Not a Vespa but I have to mount a new exhaust on the Falcon 200.

I lost my pipe once. Previously I used antiseize paste so my first question is:

* How can I best remove the left over paste from the screw holes before applying the thread lock?

Which thread lock would you recommend? Blue? White?...

There is no down pipe. It's a one-piece pipe. Six screws total. Two for the deflecting cover. And four that mount it to the scooter.

Thank you in advance.

Max.

Chase out the gunk with the correct sized tap.

You should install a loud pipe, not wear a ⛑, attach a 🔫 rack and plaster the scooter with political stickers.

If itís still not locked you might have to resort to Christmas lights.

I thought the same thing and was waiting for mods' lightnings.

That was fun. Now let's get to my question:

Blue or red thread lock? Is it even a good with the high heat?

I guess that could be called MV seppuku.

IIRC, blue is what you'd want, red is for permanent installations or if you have big forearms.

I'd check the manufacturer's website if you already have some, as I'm not sure colors are universal......

Generally
As I understand it, none of the threadlocks will stand up to high heat. I imagine the manufacturers have temp specs on their product pages.

Locally not a problem, as the fasteners corrode fast enough that the rust serves as the threadlock. Just torque to the proper specs, and keep an eye on them.

With a simple split spring washer there is no need for thread locker.



PS: but the spring washer must not be of the same brand as the scooter otherwise it is as if it were not there.

Maxx. Amazon haș a number high temp thread locker. Perhaps one of these will be suitable for you application. https://smile.amazon.com/s?k=high+temp+thread+lock&ref=nb_sb_noss_2. Read the details. Some of them are water soluble. But I agree with Attila that maybe a split washer might be a better solution. Or with Jimding to just torque it to the right spec and don't worry about it, unless of course there's something else wrong with the joint.

And I've never used thread-lock on any exhaust fittings - rather, a dose of copper anti-seize!

I'm personally much more worried about corroding these fasteners from high heat than losing a fastener from vibration. I use antiseize here - and proper torque, which I verify once a year or so - not threadlocker.
