F1 code

My riding buddy just purchased a 2008 Goldwing Trike. It is showing a F1 code,off and on. It will go away for a whole ride, and the next ride, it will come on and off several times. Bike runs great,and all functions seem to be normal. Any one have any suggestions ????

Maybe have a look here, our very own Trike Lady posted this
