An official CAA Japan notice concerns Motorcycles (Honda: Super Cub 110 MD and others) - Repair. Due to a defect in the engine (air cleaner box). ■ Defective part (component name): Engine (air cleaner box). ■ Description and cause of the structure, equipment or performance considered defective: Due to inappropriate molding equipment for the blow-by gas passage in the air cleaner box, a resin film remains in some passages, preventing them from being open all the way through. As a result, when engine speed increases, blow-by gas leaking from the combustion chamber increases the internal pressure in the crankcase, potentially partially dislodging the head cover gasket and causing engine oil to leak. Published 2017-11-10.
What to do now
(Improvement campaign) 535 ■ Details of corrective measures: On all vehicles, on all vehicles, inspect whether the blow-by gas passage is open all the way through; if it is not, replace the air cleaner box with a non-defective one.
