sentania, which paint color do you have? I have the grey/white/red/black and recently had the 10/100 stem installed. I haven't seen any paint cracking (yet) but I'm keeping my fingers crossed. I wonder if it is color-dependent? Also I may be lucky but the headset hasn't loosened either. Maybe it is my turn to have good luck because my last superbike had a lot of problems with the fork coming loose, paint rubbing off, etc... I hope they get your situation taken care of.
