An official CAA Japan notice concerns Motorcycles (Honda CB400 SUPER FOUR and others) - Repair. Defect in the starting system (starter magnetic switch). ■Defective part (component name): Starting system (starter magnetic switch). ■Condition and cause of the structure, equipment or performance deemed noncompliant with standards: In the engine starting system, improper application of waterproofing sealant to the starter magnetic switch may allow sealant to enter the terminals where the switch's fuse is installed. During use, the sealant inside the terminals may soften, reducing the contact pressure at the fuse terminals, increasing contact resistance and generating heat. Continued use in this condition may cause the fuse mounting area to melt and result in poor electrical continuity, causing the engine to stall and preventing it from restarting, or may cause a short circuit in the starter magnetic switch circuit and lead to a fire. Published 2015-06-25.
What to do now
(Recall)3603 ■Corrective measures: On all vehicles, inspect the starter magnetic switch and replace it with a defect-free unit. Also inspect the fuse connector and, if it has melted, replace the wiring harness with a new one.
