my 50cc speedfight 2 is overheating,something has melted dont know what it is but its next to the sparkplug, it has an electric wire going to it, its blue plastic and connects to something thats also melted inside a 3/4'' brass nut, need to replace these bits but dont know what they're called, also dont know where the thermostat is as this could be my prob,
brass nut next to sparkplug is. temperature gauge sender unit. unscrew and replace with another one.the thermostat is inside the cylinder head.to replace it the head has to be removed.
