Corrosion

[lostdrifter]

I've just noticed some bubbling in the paint between the cooling fins on the cylinder head which seems to be corrosion.

The bike is 3 years old and has never been in the water as I live in the desert.
Anyone got a good idea for prevention?

Thanks.

Obviously something is causing corrosion, what's the cause?
