Exporting to the U.S of A 
  Hi,
 
 I am have for some time known that I am moving to San Fran, Calafornia in June.  My question is has anyone has any experince of shipping a bike to the US?  The physical shipping is not a problem but I have been told that the emission laws in calafornia are quite strict, in fact I have been told by a ducati stockist out is CA that I need to have charcoal filters fitted to the engine which can only be done at the engine build stage at the factory.  Is this right or a load of old B******s.
