New Twin 28mm Keihins! Jetting Question?

[Thack82]

Okay, I bought a set of 28mm Keihin Flat Slides to take the place of my stock 26mm Mikuni's with T.O.R.S. Delete Kit and a Vito's Stage 3 Jet Kit (340 Mains and #30 Pilots). The mods I have on my bike are:

 

.020 Bore, Hot Rod's Forged Crank, Wiseco Pro-Lite Forged Aluminum Pistons, Trinity Stage IV Cool Head/20cc Domes, Chariot Billet Reed Cages/Boyesen Power Reeds, Chariot Billet Reed Cage Spacers, Stock Air Box/Outerwear's Lid/Outerwear Snorkel Booty, Ready High Flow Filter, Magnum Boost Bottle, Paul Turner Mids/Fat Boy Silencers, NGK Iridium Spark Plugs, Dynatec Ignition Coil, High Output Ricky Stator, RMStator Adjustable Timing Plate (+4°)Oversized Aluminum Radiator, CV-4 Cap, Mod-Quad Billet Water Impeller, TM-Design Works Billet water Pump Housing, Mod-Quad Billet Inline Coolers.

 

I Mostly trail ride my Banshee, but I do run and Hare Scrambles and do the occasional Local Fair 300ft Dirt Drags. I know it will be a job to get my jetting right the first try so I'm going to go with what ever you guys recommend as a starting point and buy 3 smaller jets and 6 larger jets and tinker until I get it perfect. I'm sure you Keihin runners can probably get dead on, so please give me all your input on the jetting and trick for getting them tuned for perfection. Thank you all so much you have been a tremendous help.

I went and put together a jet kit I ended up buying a 140, 145, 150, 155, 160, 165, 170, 180 I started out with the 160s and it was choking it so I tried the 140's and it seems to be okay. I might end up needing the 145's or 150's.
