Seem like somebody told me they stopped making them for the old MAGNETTI-MARELLI systems. I'm sure they won't retro, if harley says 02 and later they mean it. There might be something out there aftermarket? Stop by your dealer and have the parts man do a search on his computer to see if another dealer might have one of the earlier versions in stock, they have a network to share stock info, it would be better then aftermarket.
