Reamer size is not the only important consideration, you must use a
piloted reamer to maintain the hole alignment. There is an article
on-line on one of the Triumph web sites showing how use the shank as the
pilot, and modify the reamer to cut from the back side. Also the holes
are not reamed through, and a shoulder is left for the bushing so there
is no possibility of the bushing working out and binding the throttle
plate. Most knowledgeable list members would advise for you to send your
carb bodies to a specialist for this operation, but if you must do it
yourself you can search for the article I mentioned, or machine a pilot
for attaching to a hand adjustable reamer. I have used this method
successfully on kingpin repairs in the past.
