Has anyone had this problem with an 03 or 04 LTZ 400. I had a 2mm bigger piston and headwork done and after startin the bike up there is a pretty loud tapping noise that seems to be coming right from under the valve cover. Everything is adjusted correctly, and it has been suggested that the decompression part on the exhaust cam may be bad and is causing the noise. Before I start switchin parts again, I was lookin for a lil expierince with this issue. Any help or direction would be greatly appriciated.
