Good Q&A with Sebe Guillaume on WEC site, http://www.enduro-abc.com/index.php?model=news&action=view_object&object_id=473as, he is forced to retire with GasGas cancelling his contract due to financial reasons. He states his best years were with CH Racing 2007-2011. Also many pics on Enduro21.com Maybe CH can find him a bike for a few events....
Good luck to him and if he wants to take a vacation, I have a 08 WR250 and a couple 2010 TC250s he is welcome to ride March 9th at Bias, Negros Oriental, Philippines in the second leg of the Kopiko SX series .... He mentioned he has a MX background so this may not too far a stretch for him ..
