Original accel was 80, Velocity 400 (MM for units)

To get around this correctly will be uneconomical because you'll probably need to replace most of the electronics including motor. Only you can decide if the machine is worth the cost and trouble.?

I would just devise some counter weight like the springs idea has it will be a lot cheaper and probably easier.
