Just bought a 2007 ZX6R from a buddy, and when he had the chain replaced by the dealership, they did it wrong and it ended up flying off doin 100mph. The bike was fine, for the most part, but when it came off the chain gouged a decent sized hole in the plastic under the rear seat. Today I took it back to the dealer for him so they could replace the piece, and when they pulled the old one off, they discovered a sizeable chunk of it melted away, near where the E.V.A. is. The guy at the parts desk said that the initial guess is that the flapper valve isn't opening properly and causing the issue, and I was wondering if anyone else has experienced this problem. If it helps, before I got it, somebody hit it in the parking lot and it tipped on it's side, I'll attach pictures, but since it fell on the right side and the valve is on the right side I was wondering if that could have caused a problem, even though the frame slider took the brunt of it. In the first picture you can see where the toolkit plastic has melted too, and how the top part is missing a decent amount of plastic. the second pic shows the damage from it being hit.
