Citroen C4 in just had 2 new drop bars fitted but clunking noise remains from nearside

Cant be that then , You need to check susp bushes , anti roll bar bushes , top strut mountings for wear

Had a deep sort of rattle on the drivers side of mine. Happened when going over even smallish potholes, yet could drive on a good surface with no sound at all. Turned out to be the shock absorber. My mechanic, who I really trust, fixed it. he told me that this can be a problem with Citroen and Peugeot cars.
