I think you may be mixing up the power and balance Vis motors.
It is the balance one that has the ability to continuously go round and round if it is not connected to the balance flap.
The power Vis (the one on the top) could simply over rotate and stop it will not go round and round.
If your balance Vis (the one on the side ) is going round and round you need to take the top off the Vis motor case and re position the cam on the final drive wheel so it is in between the two micro-switches. then when you reassemble it do not attempt to operate the Vis motor unless it is connected to the balance flap as this acts as a stop to stop the motor rotating continuously.
hope that helps.
Now, Steve, where do you want this love bite
