I have an 07 speedmaster.
bubs, no ai, no top snorkel, oem air box and I have 122 mains and 3 shims.
it runs fantastic but I am actually changing it to 125s and will see if I need to remove one shim.
my only issue is WOT is a bit lean (seat of pants dyno).
130 mains with one shim made things sputter at about 1/4 throttle. was dynoed at that point and still got 53 FPs of tourque.
