Bubbling paint around the filler necks is another problem seen out of the crate. I saw it on a batch of '11 - '12 vintage RE's at a dealership...
The bubbling paint was an issue on my 2013. All of it is gone now, and some of it fell down inside the tank. What came off around the filler was not enough to plug up the fuel pump filter, but I am still concerned because it looks like the entire inside of the tank is painted. Some paint can resist ethanol for a long time, but it will eventually began to soften and come loose.
Those dirt bikes were several years old, and had probably had ethanol in them the whole time. The plastic was not melted, just badly cracked all over. I have other plastic and rubber melt.
Supposedly marine grade Stabil will help, but I haven't found any actual proof yet. Ethanol is some nasty stuff, and just doesn't belong in motor vehicles.
A little off topic, but I was watching this weird video on Youtube, these 2 guys were customizing a car. They wanted it rusty. They stripped off all the paint, then soaked it in beer. It rusted very quickly.
