On Honda CB400SF motorcycles, high-voltage wires are replaced as an assembly with spark plug caps.
For clarity, the wiring replacement procedure is shown on a motorcycle with the ignition coil removed.
Attention! If it is necessary to remove all high-voltage wires, it is recommended to mark their location on the coils and cylinders or remove them one by one to avoid confusion during installation.
I. Remove the spark plug caps with the spark plug and unscrew the fixing nut on the ignition coil.
