David has a true plug and play harnesses to mount and use a Fueltech FT550 system on a gen2 hayabusa. This was probably the simplest installation I’ve done.
He sent a template to mount the dash to the factory front rack, the wiring harness runs along the bike with the factory harness and plugs into the factory ECU connectors.
My bike has ran 5.60s and 8.80s all year long. Right off the trailer I ran 5.69. The next 3 runs I ran 5.66, 5.67, 5.66 and 8.86, 8.85 and 8.87.
