My dragster 125 has sprung a leak from the plastic outer head cover / thermostat housing around the hole through which the spark plug passes. I have removed the cover and there is a rubber gasket at the bottom which is fine but around the spark plug hole the plastic looks as though it has melted, I was expecting to findan o ring or some kind of replaceable seal here. Any ideas anybody.
See the green silicon gasket in the link below?That is your head gasket,it may be blown or you possibly have a crack in the cylinder head.
