FYI swollen gas tanks!!!!!

Hey guys not sure how many of the Ducati's other than the sport classics, GT 1000's and the monsters have nylon tanks. i have a 2005 S2R 800 and just bought it this march. I noticed the frame supports form the gas tank were protruding outwards from the frame. when i had the bike in at GP bikes for certification i pointed it out to them and they put a claim in to Ducati. apparently the ethanol in the fuel reacts with the nylon tank and allows it to absorb water which makes the tanks swell over time. The story i got was ducati was sued over this issue and warrantied any tanks showing this problem. GP bikes told me that they will just send larger frame supports and if the problem persists the tank will be replaced. so anyway I guess i was the first monster to be put through this precess as they (GP bikes) had only done claims for GT 1000's so they had start create a new claim to ducati. So to end this story Ducati has completely covered the cost of a new tank to be installed on my S2R!!!!! Which rocks cause it had some scratches and scuffs on it when i bought it. Just wanted to share this story in case anyone has the same issues and was un aware. I'm new to the ducati world so this might be common knowledge.
Cheers

Yeah, it's been an ongoing issue with Ducati for a few years now. I have an S2R800 as well and my tank is expanding. I had it inspected and am waiting for a response from my dealers field manager. Advice to you: send your new tank to get Caswell coating before you put any fuel in it. It voids the warranty, but will help prevent the same thing from happening to your new tank. The new tank is exactly the same as the old one, so it will swell again. You can find the terms of settlement on the internet, but basically 18 months from 2/2012 ( date of settlement), Ducati will no longer be required to replace tanks. And, in that period, if your tank is replaced, it only comes with a 6 month warranty, which is BS. So, get your tank coated. There is a bit of good news out of it though, if it does happen again out of warranty, Ducati has kindly dropped the price of monster tanks from roughly $1800 to around $1k or less if I'm not mistaken.

Not the best solution but think about buying a second tank and then swap them out periodically to allow the ethanol to dry out and the affected tank to shrink back to normal size.

I've said it several times but I'll say it again.

My Paul Smart replacement tank was prepped and Caswell coated by my dealer that replaced my tank, it has several "pluses" and one "minus" on the tank right now. As much as I wanted the Caswell kit to work, it didn't. I certainly recommend trying it because it's all we have, but don't count on it to work.

i expected to hear stories of this before now.

i can't see how the Caswell coating can be expected to adhere to the inside of a plastic tank that hasn't been physically prepped. without sanding, scuffing, etching or something to stick to, i just can't believe it works. it's a different story with steel tanks.

my prevention plan? i fill it only enough for that day's ride then put my bike away only after my fuel light comes on. a minimum amount of water-attracting ethanol in the tank when stored, then fresh gas flushes the tank when i ride.

i suspect bikes that are ridden often don't have as many problems since fresh gas hasn't had the opportunity to absorb much water

Race gas helped shrink my tank. Not convenient but some might have access.

I put in some race quality gas every now again. But at $9.99 a gallon in LA it gets a little pricey.
