I have a brand new 07 Attak with only 198 kms. I went for a ride on Saturday and the machine kept overheating all day. The conditions were plus 1 or 2 degrees celcius and wet snow falling. I was also travelling fairly slow to break the engine in ( less than 6000 rpm ). I also had to travel a little distance to get home with the temp. light on. I hope I didn't do any damage. Anybody else see this happen ?
 
Oh boy, have we ever. Overheating is common. The system as designed by Yamaha is inadequate. Lots of guys have had great luck w/draining the coolant & replacing it w/Water Wetter. I had my dealer install a rear heat exchanger but the factory tunnel protectors need to be cut & you'll have to fabricate new ones to protect the exchanger.
