Rear end has a 3.90 gear ratio for the street and a 5.13 for track days. I need help with carb selection. I did the C.I.D. x max rpm/3456 x V.E. formula and came up with needing just under 600 cfm do you think I need a bigger carb than that. Im open to all suggestions thanks a lot for taking time to help.

I am thinking a 750 is a good choice. I think anything smaller than a 650 would be to small.

I ran a 650 for years ona similar combo, never did get a chance to try the bigger carb although I suspect it would have been worth some improvement.

Just one man's opinion and worth exactly what you paid for it.
