Can older generations of four strokes be retro fitted with EFI?, Honda has been developing it's PGM-FI unit for a number of years and even had it on it's 2005 HRC Montesa Cota 4RT 4-stroke 250cc trials bike. With all the sputtering, popping, and cutting out older 4-strokes did I wonder if this is even possible. I have just been looking at used bikes and they are so cheap but seem so sketchy, and after the Super Hunky podcast rebuilding and maintaining a 4-stroke just seems like quite a commitment.
