Too much is pretty easy to determine...
If the wires going to the motor and speed controller are soft and warm than it might be too much. If the 30 amp breaker keeps tripping, it might be too much, etc.
Worried about too hot? At work we use the 10sec/finger rule, if you can keep your finger on a surface for ten seconds you are most likely running under normal conditions for the motor. As a caveat here, touch gently at first if you suspect a really hot motor. If you touch for a long time you will burn off your fingerprints.
You do know about removing the locking pawls, right?
Smoke is always a sign you've gone too far, unfortunately, motors are not self healing so this is a one time, no turning back kind of indication.
One last thing, get to know the sound of your drive system. If you hear a sound like something is complaining, then it is.
Al
