Okay, then I will ask a related question...
Question: What is the best way to balance a turkey on a rotisserie spit?
Answer: Use a counter balance weight??
Some rotisseries have counterweights that can be adjusted to provide proper balancing of the turkey on the spit.if there is a heavy side then you aught to balance it out instead of putting unnecessary stress on the motor.Use counterweights, if your rotisserie came with them, to balance the weight properly.
