Are we talking removal of a lot of plastics to get to the ECU?
I can reach and feel the ECU up above the right fork leg, may be able to pull its plug but would never get the thing plugged back in!
Removing is a big deal the first time but it gets easier each time.
1. 5 bolts to remove windscreen
2. 1 screw to remove shiny black cover straight forward (mask alongside each side)
3. 8 screws and 2 nuts to remove nose piece
ECU on machine right. Just unplug. No need to remove from frame.
