Dazco,
I did follow your advice & went with 2 shims with the TBS.
I had a heck of a time to get the diaphram in right.
Finally had to put one of them in a freezer for 10 minutes.
The Dealer helped me out with that problem.
The bike did not seem to run any better so I went back to the Thruxton needles.
I just tried the TBS with one shim.
I dont notice much difference except when I hit the limiter it was`just a sputter instead of dying.
I am going to schedule another Dyno.
