Sounds like this is the only other thing besides a short wire somewhere or the ECU and I'm told it's unusual for those to go out. Thanks for the help, I'm off the the shop today to get a relay box ordered!!!
I know this is an older post but did anyone ever get to the bottom of this? My bike is having the exact same issue.
The starter motor is either stuck on or it comes on and stays on when you drive down the highway...
