So my 2011 Vision; while sweet in every way; seems to have an issue with what looks like galvanic corrosion on the exhaust header nuts and clamps. They're turning white and a little powdery like. Is this normal on the 106 engine and the exhaust system? I don't ride it in the wet nor in salty conditions (during winter).

How can I combat it?

Mine are white-ish. Not corroded. Just a bit white.

Spray a little WD-40 on them, after a few minutes wipe the area down and they clean up pretty decent.....You can also use CLR on a rag but be real careful not to use to much or get it on bike or paint....Wipe it off soon and keep it up until area is totally dry......

I went to Ace Hardware and bought 4 chrome acorn nuts. Although they are kind of hard to see, they dress the area up a little, and no more corrosion.

Mine are totally rust looking and no big deal but what scares me is the studs might come out with the nuts.
Funny out of all the V Twins on the market there are so many cheap corner cutting on the Vic bikes.

Easy to stop the worrying, Johnny. Take each nut off one at a time and put some never seize on the threads then retorque the nut. If you do them one at a time, nothing should come loose. When you need to take them off to replace the exhaust (?), they'll spin right off, leaving the stud where it belongs. If it looks like the stud is coming with the nut, heat it up slightly then try to tighten it before loosening it.
