hi vinney i would go for the head set bearings also, if they are no good replace them with standard bearings as yamaha did not put tapper ones in and also they dont fit as ,i found out on my 400 dx
i have just bought 2 yg1 80 cc basket cases do you still require this part if so will have a look for it as the bikes are in pieces oh by the way how closely relayed to the fs1e are the engines,as i may require crank and piston 0r do rd 8o bits fit
