SPEED COSTS MONEY. HOW FAST DO YOU WANT TO GO??????????
More likely stator. CDI's rarely ever fail.
The 97-99 Red Heads spark all three coils at the same time so if only one is sparking check spark plug caps, coil wires, wiring to the coils, and proper coils installed. If all that checks out then its prob rusty flywheel and or defective stator.
Move good coil to another cylinder and see if the spark follows.
