so I bought a Honda head a little while back and between some conversation with my brother I have a bad feeling they sold me a clone head and not a Honda. not as if they ripped me off but like they miss understood me and sold me a clone head. I think the numbers on the casting are Z4M I could be wrong it's a 18cc head. can anyone help me??? and on top of that I have a real gx200 and it says that right on the head even though that head is 22cc so I know it would be different. anyway I'm really worried please chime in guys. thanks for any answers
