There's a shift light? I thought that's what the RED part of the tach meant.

By adding higher-lift cams, better retainers and heavier springs, you can get the motor to run higher than the original redline.
FYI: Most powerbands peak before the indicated redline anyway. Going to the redline normally is not gaining you anything, and can cost you time.
