I crashed about a month ago, 5 weeks maybe. Broke my leg. Just pointless back story. Anyways, as a result my bike has been sat in the garage awaiting repairs. I've turned the engine on once a day and let it idle for 15 mins or so just to keep battery charger and engine in a running state. I forgot to do it the last couple days, did so today, and I've been faced with this error message? Er_1 and no rev counter? I've looked online and only found an answer for the R1 and that it could be an ignition fault, something to do with no signal being recieved!? I also saw it may be an RCU thing.. as an amateur I haven't got a clue I'm hoping someone on here might be able help me!!
