Great work Antony - I so wish I was doing DD but nevermind....
Carbs - glad you got them looking good, mine had just a much gunge in them after being stored for '6 months' before I bought it (900ss).

American - but check out some of the links on the left here:
http://66.47.68.116 Just an idea about the choke cable etc - my trackbike has a simple cable tie sticking out under the tank - I'm sure the same system would work easily for our carbs as well - you might need to link two cable ties together but, its cheap and cheerful!
Cant remember DD rules - but quite surprised you didnt go for a dynojet kit when going for a big-bore as well?
Fastners: Ebay is good for all sorts of stuff but its worth while hunting down some good local faster / nut and bolt specialists.....here is my local one that has been SUPERB so far...

I like the updates - keep em comin please - Frank
