I wonder if ne1 has engine noise in there ltz-400? I checked the valve gaps and they were bang on and the oil is fine[right level] and there are no exhaust leaks but there is still an engine noise[top-end] Also the cam chain seems fine[not loose or worn]. Has ne1 experienced this and what did they do to correct it?

 

Look at my topic on the Cam tensioner, most likely this is your problem. Suzuki knows about it.[img]i/expressions/face-icon-small-mad.gif[/img]
