1200 goldwing
hello everyone, when motor gets warmed up it has a knocking sound when you get above 3000 rpm. if its pulling or holding back it don't do it. I changed oil and put 3 oz of sea foam in it but it didn't help. it runs great and as long as you stay under 3000 rpm it does good. thanks for any help.
