Clock Swap from a YZF R1 to my FZ1

[Geowulf]

Thanks for that, it really helps, so is RN04 the 5JJ (00-01) R1?
I think RN01 is the 98-99
and the RN09 is the 02-03.

There is a tiny discrepancy between the first and second RN04 pinouts Fuel sensor is G or G/W, doesn't really matter as they are both fuel level and the pins are in the same place.

Any idea why the speedo is reading zero? I'm pretty sure I've rewired the plug correctly.

Also, interestingly; the RN04 speedo seems to have picked up Fazer's correct mileage, it's either an amazing coincidence the both bikes have the same mileage or the mileage is recorded on the ECU and displayed on the tacho.
