My setup matches your exactly with the following exceptions:

- '05 TBA
- TOR longs
- 3.5 turns out when using stock idle mixture screws
- 2 Shims on stock needles
-- Used small brass washers found at Home Depot
- I synch carbs after every tweek using following method:

>$10 Carb Synch

I can't comment on "airy" pipes as I've never had that problem, but no "bogg"ing with my setup. So... give the shimming and synching a try.

Tom
