After reading the thread I'm still trying to understand the cause. If there's a bladder then there is no contact with fuel to the outer shell so it's not the Ducati problem where the ethanol causes the tank to develop bulges. If it's expansion then it would be easy to reduce the volume of the bladder or adjust the shape to allow a little clearance. If it's stress related fracture due to vibration etc then why wouldn't it be beefed up a bit in the areas where they crack? So what's going on here?
