Listen this might sound strange, but mine does this all the time, and all you need to do to reset is the following:
while bike is OFF
press and hold down the 2 shift arrows, and then turn key to on position. (not running the engine) then press the down arrow, then up arrow, then down arrow, then press down the throttle all the way in. et VOILA your blinking has stopped.
This sounds like a crazy nintendo trick but it works.
