WHAT ARE YOUR CARB SETTINGS WITH A BIG BORE KIT?

There are many combinations that will work, but I thought
it would be fun to compare and see if there is a consensus.

MY SETUP:
904cc Big Bore Kit (from South Bay Triumph)
Predator exhausts
no air box
no air injection
stock CVK36 carbs

140 Main Jets
45 Pilot Jets
NBZ1 Thruxton Jet Needles
Pilot Jets drilled out from .016 to .018
Slide Lift holes enlarged to 3mm
No shims
Idle Mixture screws set at 1.5-1.75 turns out (idles at 1100 RPM)
Also, used a single tube instead of two vacuum caps
