SX/SXi/SXi Pro 750 SP on BP bottom end rec port jetting recommendations

Dropping in a frankenstein 750 motor into a 650sx and I am looking for some baseline jetting recommendations. Not much of a clue where to start.

#22 SP750 cylinder with rec porting (40.25MM exhaust port height)
BP bottom end
650SX ignition
Dual SBN44's on PJS manifold w/reed stuffers
Factory Pipe 650 pipe
ADA head with 28cc domes (hopefully be fine with 91 octane fuel)
Skat Trak 9/17 standard or maybe a big hub
PJS Exit Nozzle
Pro K Flame Arrestors

Any help is greatly appreciated.
 
I'm interested too although mine will probably be different than yours, I'll be running non ported #20 cylinders 81mm w 750 Factory limited on bp lower with blackjack modified sxr carbs.
I have this set up on my ski, except my carbs are not modified. Im running the recommended factory pipe jetting for SXR except 75 pilot and 2.0 N/S with 80G spring.
