SX/SXi/SXi Pro Jetting suggestions for 750

Having problems dialing in my dual Keihin 38 carbs. I'm running a high compression head 183psi, R&D timing advance, dual blowsion flame arrestor, and stock pipe.

Running stock jetting, hesitates on the low end. Tried backing out the low speed screw with some but little help.
