In setting the predator RPM limit on the stand does it make sense to set it at 4850 to not go over 5000 when the motor is only turning 45-4600 on the track? Why would you flirt with over 5000 setting the rpm at 4850 when you are not turning the motor but 4600? I'm new to predator and not and engine guy so I'm trying to make sense of this.
