Cam chain rattles when cold

[Speed_imp]

You might do a search in both the General Section and Mechanical Section of this forum for engine noise or noise from bottom end. I know there were some extensive threads on this topic very early on when the forum first got going. I recall one guy's noise was so bad the dealer pulled the timing chain and guides and replaced all those parts under warranty. Some changed oil brands and this appeared to help or resolved the issue. You almost have 2000Km on your current oil so you might start with the most obvious and cheapest remedies first and change the oil. Sounds like you are using good quality oil with proper viscosity. I am using Repsol 4T Synthetic 10w30 in my bike and not so much as a hint of noise. I changed mine at 500 mi and then again at 2,500 mi. Good luck with it.

Now that I hear that someone had to remove the cylinder block to change cam chain and guides under warranty I feel much better . Ha ha ha!!! I am praying the lord that it's only a bad tensioner...
