After posting my thread on twin plugging an older 'SS' bike, I thought I'd look up the guy who twin plugged and gas flowed a BWM twin that I had years ago.
  His site is full of all sorts of bits and bobs including some Duke heads and barrels for sale as well. 
 I was quite surprised that he offers all sorts of head work for modern Dukes as well. 
 I have no other connection, other than a happy previous customer and cannot vouch for any Ducati work (but hey! he has done work for Baines racing before!!)
