A clink-clink sound in the headlight when going through bumps?

Hello.

I hear a noise, like a clink-clink, when I go with my 2018 CB500F through bumps in the road, but only when the bump is somewhat stiff. The sound is like that of a metallic piece hitting against some hard plastic, more or less. The sound comes from just behind the headlight, or perhaps from its inside.

I've tried to replicate the clink-clink sound, while stopped, by putting sudden pressure on the front forks and then letting go, but the front suspension dampens my efforts and I cannot make the sound happen while stopped. But when in motion passing through some brisk bump, it happens again and I can hear it.

I've investigated with my hands all around the back of the headlight and I cannot feel any loose thing there. Everything feels to the touch as being well put and properly fixed.

I'm beginning to fear the sound comes from the inside of the headlight, perhaps the soldering of some LED has gone?

Anyone else has experienced this?

PS: My instinct tells me this it is not a serious problem, but it is very detrimental to the joy of the ride. I guess you know what I mean.

PS2: The sound in question is not caused by the keytag or the key. I've tried going with the "naked" key, and I still hear the clink-clink when through bumps.

Have not experienced this but it would seem logical that you need to remove the headlight from the nacelle and "have a look". Once the nacelle is open to view, you might tap it with the palm of your hand to see if that jars anything loose, causing the source of the rattle to be more detectable. You might first tap the handlebar bracket with a rubber hammer for the same reason. But that Texas is a long way from Madrid, I'd love to help troubleshoot this annoying problem. Please follow up when the problem is solved.

Thanks for all the suggestions. The rubber hammer is a nice idea. Removing the headlight scares me a little as its body looks very plastic-y and therefore brittle - I don't want to crack anything there. But ultimately I will have to do it if I cannot find the source of the problem.

Will keep this thread posted.

Those Pesky Gremlins are at it again... You're probably correct believing it's not a serious problem, but strange noises bother me to no end. Good Luck finding it.

To ride or not to ride? What a stupid question!... Anon
