Just recently acquired this bike and needing a little guidance. It was not shifting at all. The esp light is flashing (6 blinks). According to the service manual it is the code for the ecu. Well I replaced the angle sensor the shift motor and the ecu. I did the initialization and heard the shift motor sync. It's still blinking (6) and it's giving the -- where the N is supposed to display. I just recently rebuilt the top end but I'm not wanting to dump a whole lot more into a bike that's going to be used to haul deer out of the woods. Any ideas or suggestions would be greatly appreciated.

Had this exact prob with the same year machine. Ended up being the connections under the 'hood'. Just another spot to check, the connections were just dirty & once unplugged & plugged back in it was fine for years. Cheap & free to check, so i would at least try that.
