Pack seal for high engine original 50cc Ø39mm AXWIN liquid on MBK 51 / av10 motobecane

Engine seal pack for MBK 51 / Motobecane av10 liquid! This pack has O-rings for original cylinder head or original type, the exhaust gasket and the valve gasket. Everything is of very good quality for a fairly low price. We regret that the base gasket is missing!
