Well I just got my SERK (put the 07 Goldwing up for sale) anyway,love the bike but seems to have alot of noise coming from the chaincase,esp when cold,also I hear what sounds like rocker arms rattleing every now and then, the valve noise dont really bother me but the knocking in the chaincase does, the twistgrip sensor went out on the first ride,and afterthe Techreplaced it,he took off the side cover and said the center bolt had loosened up,so he put blue lock tite and retorqued it,but it sounds just as noisy to me.
