Check the kick stand switch first make sure thats fully pressed, then check the tiny switch in the clutch lever after time that will go bad. For both you can by pass them if you cut there wire and join them together.

Check the connections under the side fairing. Take them apart and clean the connectors with qd electrical cleaner. My bike did the same thing. Good luck.

I was dealing with a theft recovery where the ignition was missing. We just jumped the wires on the harness(like you can with an R1's harness) and it did the same thing. Turns out there's a special resistor in the ingnition and if thats not there, it wont fire, I ended up getting a new ignition for it and fired right up.

Trace the wiring from the ignition switch to the connector plug that attaches it to the main harness. That's almost assuredly where your problem lies. You'll have to remove the right-hand side fairing to get at the connector. Do as the guys said above - check the connection, make sure all the wires are intact, clean the contact (DISCONNECT THE NEGATIVE BATTERY TERMINAL BEFORE DOING SO), etc. If everything checks out & you're still getting the error, the problem's either in the switch assembly itself, the wiring leading from the switch assembly, or the wiring of the main harness leading to the switch assembly.
