I’m looking for some help diagnosing my xr…
I have an 04 xr with 14000 and I noticed the other day that while the engine is at operating temperature this is a prominent clacking/knocking noise while at medium load. It usually happens when I am in 3rd through 5th gear on the throttle.
I initially thought it was cam chain tensioner related so I took off the valve cover to inspect and have not found anything particularly concerning. The auto decompression components look fine valve lash, while not perfect, was not too crazy. The cam itself has no nicks, dents or grooving. I did drain the oil and found a slight gray sparkle to it but nothing big. I can pull the filter to post a photo of anything I find in there if that would be helpful.
I’m not super sure where to look next any ideas would be appreciated.
