I was down at Pure Triumph last week and I saw a set of these installed on an 05 Bonnie that also had a BB just done to it. I know the manifolds had to be changed. I did not ask about the head ports. I will talk to them tomorrow and get more info.
The owner wanted the shop to do the break-in and pick it up 'ready to go'. Pathetic.
Like biker says, you should have the big bore for these carbs because 39mm is friggin BIG! Overkill for a stock motor. IMO and looking at the price difference between Mikuni and the CR's, I'd opt for the Mikunis.
