I already removed the head and cylinder from the ciao, but there seems to be no damage at the cylinder nor the piston. There is no gasket on the head, which is weird, and the gasket from the cylinder seems ruined like over torqued. What you guys recommend me to do? To buy the whole kit piston and cylinder with its gaskets just to be on the safe side? To buy the 70 cc kit to make it faster? Or just the gaskets and see if that will solve the problem? thanks a lot for your up coming comments and regards!!!.
