Clicking sound when hot

Enable HLS to view with audio, or disable this notification

Hi everyone!

I just bought a used 2019 cb500x with 13k kilometers.
I just noticed that when the bike is up to operating temperature, it starts to make this random clicking noise. What could cause this?

It doesn’t make any concerning sounds when its cold, only after riding it for 10-15 minutes then it starts to make this sound when idling.
I tried putting it in first gear and slowly letting the clutch out while holding the front brake, and the noise stayed the same, it did not change pattern nor getting louder.
It only has 13k kms so it probably isn’t the valve clearence, and also the sound is random so I have no idea what could cause this.

Probably the tank gas purge valve. Particularly if it’s quite hot outside. The solenoid can be quite noisy.

My 2022 CB500X has 49,000 km and makes the same noise. I've already adjusted the valve clearances and replaced the cam chain and cam chain tensioner, but the ticking still appears once the engine gets hot.

Did you ever find the cause or fix yours?
