Re: question about 49 and 80cc
I will do that when I have a reason to pull the head. It's running fine now. I'm not sure but I think I have read somewhere on one of motorizsed bicycle fourms that the 49cc/47cc engines have a smaller size head stud 6mm I think and the bigger engines have a 8mm stud. I haven't checked mine yet, I did check the torque on the cap nuts but cant remember what size socket they took. Anybody know if this is correct about the different size studs?
