Annoying cracking sound when moving my handlebars to the 90 degrees to the left/right and sometimes just randomly. I've tried re-tensioning and re-greasing everything but no difference. Going to check out the cable ends shortly and then a proper disassemble and clean... and then give up and buy a new headset I suspect. Gah :/
Make sure you haven't over tightened the top cap. I had this on my Wilier. did the strip down thing but on re-assembly put very little torque into the top cap and it solved the issue.
