Took my 02 Ultra with EFI to the dealer because it was running rough like it is missing when running at low rpm's 2000 to 2600 and not under load. Found out that there are about 3 other bikes in town doing the same thing. Dealer contacted Harley and were told that this is a problem around the country. They are sending a whole complete new injection module to try. Don't know if this is a redesign or what but will let you know.
