Help with 44 mikuni setup

[Braaaaap]

Hi,
I run a 61x cilinder bored to 760 fully ported, msd , b-pipe etc. Etc. I cant figure out the setup of my dual 44’s mikuni carbs for maximum bottem end power.

Low jet?
High jet?
Needle/feed?

Can you help me ??

good starting point

GP760 44's a good starting point is
115 pilot
130 mains
1.5 n/s
65 gram springs
1 1/2 high and low to start with.

I started with this (JM's suggestion), not exactly sure where i ended up i know i added more pilot and lowered the popoff a little.

115 high H screw 7/8 turns out
115 low L screw 1.5 turns out
2.0 / 95gr spring (22psi popoff),epoxied crossover
