I have recently returned my Mark V to the road following 40 plus year of storage and am in the process of coming to terms with its foibles. I suspect that my principal problem lies with the Magdyno as it is unreliable. Should I have it completely refurbished as original or introduce electronic ignition? I would be interested to hear of members experience and advice. Of the manufacturers offering this facility I feel most comfortable with "Thorspark" as it actually illustrates the very Magdyno on the bike and I understand that the ignition kit is contained completely within the magneto end cap.
However, if I am going to take this route, I want to make sure that it is the best option available.
