The C.E.O is a revolutionary design to the modern 2stroke motor. The design has been worked on, developed and redesigned many times since the 80’s when ESR first tested it.
Don’t understand it? Well here is a quick laymen’s description of what’s going on.
On a 2 stroke during the up stroke fresh fuel/air is pushed out the exhaust. It’s the expansion chambers job to push that fresh charge back into the combustion chamber. This is where matching the pipe to the porting is so important. With the C.E.O. dished piston top, instead of pushing that fresh charge out the exhaust it forces it into the center of the piston. This is optimizing the efficiency of your fuel/air charge when it’s “off the pipe” allowing the motor to still run optimal even when your not in the Goldilocks zone of the pipe and porting matching perfect. This drastically broadens the powerband, and truly turns your bigbore kit into the “4 stroke killer”
