Loud noise at full throttle
I am experiencing a loud noise at full throttle once up to full speed. It occurs when the bike is warm/cold and on and off of the stand. I’ve checked valve clearance, exhaust mounts, air/fuel ratio, air filter, spark plug. I tried sounding out where the noise was coming from exactly and it just sounded like it was coming from the center of the motor. Any help/suggestions would be appreciated. Thank you
