cat007 Member 236 Member For: 6y 3m 15d Posted 10/09/22 03:24 AM Share Posted 10/09/22 03:24 AM I've only just not listened to your audio clip.I used to have the exact same sound and I was original tensioner and chain etc. I've since changed to Empire for both and I hadn't noticed the sound but have a loud exhaust on so that drowns it it. *edit I have just checked and I no longer have the sound....the only thing changed in my valve train was the chain, tensioner and guides.
