Small bubble at the hearder pipe

[beemerlover]

Noticing bubbles developing in the pipe close to the engine.. anyone noticed this ??

The "bubbles" are aligned.
Looks like a canvas of some sort has been in contact with the hot pipe, and partially melted.

That looks like something rubbed against it while the exhaust was hot.

They are not just imprints but bubbles and protruded

Try to scrape off some with a plastic tool (in order to not agress the chrome) and you'll know what it's about.

I am with an earlier poster ... something touched while hot ... I had similar spots ... never quite sure what did it and it was a bitch to get it off.

Looks like a microfibre cloth has made contact whilst hot

get some very fine wire wool and squirt some WD40 on it and gently work the area. Fairly sure it will come off as I’ve done it myself several times

I’ve got same thing after using a microfibre towel on hot exhaust.
Able to remove it with belgum polish .

There's no way corrosion could create aligned bubbles.
100 % sure it's melted textile.
Look at your trouser, your cover, your jacket ....
I burnt one of my jacket at the same place when hanging it on the bar.

Been there done that.

• Spray Easy Off (the no fumes version) while pipe is cold. Cover all other surfaces with those blue mech towels.
• Wait 4 minutes. Remove blue towels.
• Turn bike on 3-4 minutes
• Scrape off with a wooden spatula (assault on wife’s kitchen tools)
• Clean off with WD-40 and blue towels. Do not use microfiber cloths!!

After you clean it off, you may notice some spots left. You may have to repeat the process.

100% positively a microfiber cloth while still relatively hot.

Make sure pipes are cold. I would try some simichrome, comes in a tube. It will take pretty much anything off without dulling the finish. If the chrome itself is bubbling, and it's between the pipe itself and the chome overlay, that's a different story. That might be from a very hot pipe coming in contact with something very cold. If the chrome itself is bubbling or flaking, check with the dealer if the warranty is still in effect. Otherwise that pipe has to come off and sent to be re chromed.

Good luck.
