Скачать или смотреть CBR1000rr SP: Cam Chain Tensioner going bad (strange metallic sound at 5.5k RPM)

UPDATE: As of 2023 I've re-titled this video to make it clear what is going on in case anyone had the same symptoms as I did and were trying to diagnose the problem. In this instance, my camchain tensioner was going bad and this was the result (the noise was subtle and gradual but began increasing in volume over the next few days).

Replacing your cam chain tensioner is easy and should resolve this if it's happening to you

***original video description below*****

I've just discovered the bike has a pretty bad coolant leak but, yesterday, after watching my videos from my ride I noticed the bike was making this metallic sound at around 5.5k rpms (you have to listen closely but it's almost a subtle grinding noise).

Wondering if it's the water pump that went?? Any feedback would be helpful

**EDIT: Water pump AND thermostat was replaced, but the sound remains. Really stumped on this one
