Sounds like we have to see your spark plug colours (side view and center view too)
123 kmh / 77mph = I would say 90mph is the factory speed because over 100mph all the time will be big issues later. So 76 is not too far away from 90mph
Hopefully also you can take a video of the “unstable” idling (but alas , the rpm rev counter isn’t working) – Is there also a wrecked bike in your country to try another matching display dashboard ?
