    82 550m timing question

    This is probably a silly question but I need some reassurance.
    I have just installed a Dyna S on this 550M that had a bad ignitor. The bike has a mechanical advancer with all the timing marks for the 1-4 cylinders but there is only one mark for the 2-3 cylinders, the TDC mark I believe. There are numbers 470 where the marks would be. I have attached a picture. Won't the marks be the same distance apart as on the 1-4 side? My next step will be to make my own marks. Does anyone know where the full advance is in reference to the 470 marks? Thanks for any input.

    Print off the timing degree wheel. Paste it to a cood solid piece of wood or cardboard about the thickness of the washer on the Dyna S.
    Line up the TDC 1&4 and put the wheel on 0.
    Now using static timing see where you are at and you can make your own timing marks.

      Distance between T and F is the same for 1-4 and 2-3. Just measure and make your own F mark on the 2-3 side.

      To measure is to know.
