    Yamaha 1200 NPV Head bolt sequence

    Anybody know the proper sequence? There are squares and circles with numbers on them each having their own set of numbers? I'm guessing that you start with the squares 1-15 then the circles 1-14?? The service manual I have is not very clear on this. Can anybody help me out?

    I would say do the circles first then the squares

    The key to torquing any part is to start in the center and work your way outwards

    Here is the torque sequence. Hope its legible enough to read.
    If memory serves correct:
    (Circle) is first pass
    [Square] is second pass
