Hi all,got a problem with my series 2,its a zvh and just need some advise on what you all think it is.Whats happening is when im steady away up the revs there is a rattle noise through the revs but when on load or pulling away hard its not there.When its ticking over it sounds fine and when you rev it up you get the rattle.any idea what it could be, its got a piper 285t cam and im siding to that.any help would be great.cheers adam
