I had my first mechanical breakdown with my 09 450. I have a rear flat tire. Put air in it yesterday and today it is flat again. So all you honda owners with your valves, kawasaki with your pistons, and suzuki owners with your soft cheap bolts stripping out. I HAVE A FLAT TIRE. Guess I will just get rid of it. I am not putting that kind of money in a 2 year old bike.
