An official CAA Japan notice concerns Motorcycles (Honda Grom and others) - Repair. Due to a defect in the fuel system (fuel pump). ■Defective part (component name): Fuel system (fuel pump). ■Description and cause of the defective structure, equipment or performance: Due to an inappropriate material used for the resin inlet cover inside the fuel pump, prolonged immersion in the test oil used during manufacturing may cause the inlet cover to swell during use and interfere with the impeller. This increases resistance at the interference point. If wear particles generated there become trapped between the inlet cover and impeller, in the worst case the fuel pump may stop, causing the engine to stall and preventing it from restarting. Published 2016-09-08.
What to do now
