Thnx for the input chopper, there's most likely a good reason Harley switched to Delphi from Magnetti and you can bet if the new single fire dosn't work out i'll be asking more questions.What happen to the MAGNETTI MARELLI we worked on was the throat got worn so much there was space around rhe butterfly valve that made it untuneable, I've seen that on some older super B's. The older stage 1 downloads were off street use and the new HD stage 1 down loads for newer bikes are street legal but adj. enough for A/C & mild pipes, Thank you EPA.
Hope the new ignition does it, let us know.
