please help w/ overheat

[fun-times-always]

first post here, a friend on mustangforums recommended this site to me concerning a problem with my 2004 R1. the bike has 5000 miles on it, mostly stock save for exhaust, intake, and other small stuff. the story is mostly i brought the bike to a self car wash to hose it down. it has ran just fine the entire time i have owned it, but after washing it, it was overheating on the way home bad. i stoped a couple of times just to get it 15 miles. the light comes on, on the dash. is there something i may have hit with that sprayer or pulled a wire off or something of that sort? i am pretty new to the bike world. any help i would appreciate much. thank you much. my intent is maybe its a quick fix insted of paying a dealer lots of money for.
