You will have a wider field of light but the high beam part when running low beam does have a different beam angle than the original, it slightly raises from the right side. People passing from opposite side will not be affected, I have tested in very dark room.
I didnt need to remove any fairing for the job. The wiring harness you need to cut is on the clutch side of the bike going from the controls to under the steering head(its a black rubber holding all the wires in). After youve added the metal piece to the high beam connector and secured the wire...
Yeah you will need a FZ1 gas tank to fit the bigger airbox and the throttle body as well as the exhaust headers. You will need the FZ1 Ecu harness as well. I am thinking about doing this swap so let me know if ever you go for it!
I swapped in the FZ1 front suspensions with the front rim and shaft (rotors and/or brake calipers from fz8 can be used) fully adjustable and worlds of difference i could finally brake hard with confidence. Easiest mod and best bang for the buck
