I'm told dome size does not matter in regards to carbs. But with a mod pipe, shaved head, and 38's, I was running:
75 pilots
135 mains
stock needles/springs
screws at 7/8
On headpipe:
bottom closed
mid 1/2
top 5/8
It absolutely ripped on low-end and mid. I have no clue what it really did to top end but I assume you don't care. A low-end prop will help realize the potential of this setup.
