Buddyclub N+ whistle sound when hitting small bumps

[E_Honda]

I've only had the BC N+ in for a few weeks and i'm hearing a brief half a second whistle noise each time i hit small bumps, sounds like its coming from the front left damper. At slow speeds i can't hear it, although from say 60-100Km/hr its noticeable.

I don't know exactly how these dampers work but its like the damper hits the bump and is loosing some gas pressure and therefore giving that whistle sound as the damper compresses from going over a small bump.

Its difficult to explain but i think that gives you guys the picture of what I'm hearing.
