    Stop cussing that early EFI system, just replace it! Zipper’s has taken the popular ThunderMax® EFI electronics and merged it with a single-throat Delphi®-style throttle body (with the help of some specially made parts) and developed this full conversion kit for bikes with H-D's earliest Magnetti-Marelli EFI systems. This kit allows you to retain the original wiring harness and gas tank, while upgrading to similar components used in the highly durable and reliable Deplhi®-based bikes of 2002-2005. In most cases at least a 1 week lead time is necessary to get the kit built and shipped.
