Went out to the garage to go for a ride Sunday morning and saw the tank on my brand new 800SS was literally sucked in about 1", and creased in three places. I assume it was from a vacuum created in the tank. Nothing fell on it - nobody stepped on it. I did nothing different on saturday than i have done a thousand times before..... Stopped at a bike shop Saturday afternoon.... came home when it started getting cool..... parked it in the garage. The horror came the next morning when i saw the gas tank....... The gas cap was fairly hard to open, and it was pressurized when i opened it. Any help??? Anyone heard of this happening to anyone else. Am i going to have any trouble getting this replaced under warranty? The shops were closed yesterday, and today, but I am going to load it up and take it to them tomorrow. Thanks for any help...
