Re: loud knock in 1980 goldwing gl1100
Could be a couple of things. Can you narrow down where the knock is? Right or left side? Is it constant? Changes with RPMs? More so under load? Sometimes, when carbs are out of sync, motor will run rough or sound like it's knocking. When was last time they were synced?

Post a video.Operate the camera from one side behind the engine,all the way around to the other side.Keep it smooth.This gives us a 360* audio/video tour.
