If you have 08+ bike, then there are few major ballaches on gauge replacements:
- Your bike will not start without OEM gauges online on the CANbus (meaning you will have to hide them under the tank somewhere).
- As the ECU <-> gauges communication is mostly CANbus, you will have to tap most signals at the source sensor -> you will end up with a bit of an untidy octopus of wires.
- As the some signals are coming from ECU only, and are CANbus, you will lose these signals altogether as you cannot pipe them to new gauges.
