Hayabusa 2005 F1 - C27 error code
« on: July 29, 2023, 02:58:18 PM »
Hey guys. Just thought I would ask for help with an issue that is ocuring in my 2005 Hayabusa.
So I get a C27 code after starting up, the bike starts and runs on 3 cylinders, its got new spark plugs and new ignition coils, I checked the connector on nš4 ignition coil with a voltage meter and its got power. I donīt know what to do to get the bike running.
I need help guys, this is my daily ride and my dream bike, I am not giving up on her!

Is the plug on the dead hole wet or dry after you run it a minute?
