My temp owner's manual shows that S65 is a "sequence fault".
In the startup procedure, after turning the key on, if I press the starter button and turn the throttle at the same time, or turn it before the software has completed the task of making the motor available to the bike, it will throw the S65 fault. Solution, as you discovered, is simply to start over.
Makes sense that you wouldn't would the motor to become hot with an open throttle!
To avoid getting this fault, I slow down, act deliberately, and all is well. Just as Brian intended.
