Bubbles forming under the paint of fuel tank

I've got a 2008 Hyosung GT250R and a few days ago I took it out and noticed there was a small bubble, about 1 cm in diameter that formed on the right side of the tank. It concerned me at first, but I haven't had any free time to look into it.

I went out for a ride today and noticed the bubble has gotten much larger; probably about 2-3 cm in diameter.

I was hoping someone may be able to shed some light on what may have caused this issue and how I might go about correcting it.

Thanks,

Brandon

If it is a plastic tank it is gas leaking throught the plasic peeling the paint. Ducati has a huge problem with this issue as well http://www.topclassactions.com/laws...s/901-ducati-defective-fuel-tank-class-action. You will have to get a new tank try and get one free from Hyo as it is their problem

The tank is metal and the bike is out of warranty; it only came with a 2 year and its hard enough getting them to honour warranty work as it is.

There is probably a pin hole in the tank (rust?) you can get the inside coated or replace it.

Are you sure its metal? (not calling you dumb, but people make mistakes)

If you're right, then the bubble can only be paint. Not sure what would cause that... I guess fuel could've gotten on it and it was already damaged or something. I doubt a metal tank would have a perforation in it under the paint.

If the tank is plastic on the other hand, lots of bikes have this issue. The plastic reacts to ethanol in pump gas and deforms. Ducati uses Acerbis gas tanks, like many other manufacturers, so they have that issue.

You can put a hole in the bubble and see if it is full of gas to test if it is coming from inside the tank.
