    Bad because your carb setting will be way off resulting in POOR performance. Bad because when you shut down the engine cold air can get back to the valves and cause damage by causing things to cool too quickly. Bad because it is noisier than H*LL which only makes people angry with you.

    Very bad the motor needs back pressure. Also the quad runs with a proper mix from carb for air fuel.
