GY6 150cc "terminator" head gasket
 

I am in search of a headgasket for a "terminator" engine.
I ordered a set of GY6 gaskets and they don't match the
original.
The old head gasket measures about 57-58 mm for the bore and the diagonal holes measure between 79-80mm.
The new gasket in the kit measures 59mm (bore) and 76mm (diagonal measurement) respectivly.
Any ideas on what I have?

:banghead:

sounds like a type b motor. do you have 4 valve cover caps or two?

If you mean the through bolts that hold the valve cover to the head.. then two.

I have ordered gaskets and hope to have them by mid next week. TOM
