I have a 08 CVO roadking with 18,000 miles on it. It has had the recall work done,base gaskets,ect. When it gets hot it sounds like rocks rattling in a tin can ! Can't tell exactly where it's coming from but I think it's the lifters. I'm gonna try a set of S&S high performance premium lifters and adjustable pushrods and see if that quiets it down any. Anybody else had this problem and if so what did you do to fix it.
