I have recently brought a 2020 honda cb500x and it won't fire up! the light come on and it turns over but that's it! i have had the seat up and can't locate the ecu? I'm unsure wether i need to purchase a new ecu or a whole new lock set with ecu included? someone said i only need a new reciever? I would be very grateful if anyone can help? At the moment, i have only spent 30 mins on the bike but, if anyone can save me time and money it will help me out alot! At the moment, i'm not sure if the people that stole the bike removed the ecu? so if anyone knows the location the would be a start???
