    Yamaha 85 steering link, lock nut thread size?

    if its the one i think you are looking for its 5/16 unf , i dont know why they went imperial on that bolt and the thread in the arm. kind of a strange one because a 14mm ring fits the lock nut perfect, 9/16 is a bit sloppy.

    5.7 hard start

    fuel should go to the injectors first then what is not used goes back to the tank , in short >the pressure regulator defines how much fuel goes to the return. if injectors are not spurting fuel then all the fuel gets returned to the tank.
