Re: 2004 gsxr 600 engine knock Help!!!
Cam chain tensioners were a problem on the older bikes, not these. Sounds like it's running on three cylinders. Take the body work off and let it warm up a little. Put a little water on the four exhaust headers. One will be cooler than the rest. That's your problem cylinder. I does sound like a blown out plug, but it's hard to tell on a video. Find the bad cylinder and go from there. If the plug looks ok, do a compression test on that cylinder.
