Hi I own a 57 Es2 500 single and am wondering which way to go with the electrics and the best way to go about doing it .should I stay 6 volt or up grade to 12volts .Should I bin the old regulater and fit a 12 volt regulater change bulbs and battery job done or use a 6 volt solid state regulater and fit 6v halagen bulbs ? would the engine spin fast enough to spin the dynamo up to 12volts out put. ok on long runs but round town may be not .Any ideas......Cheers gaz
