4A-GE + Keihin Carbs

Anyone got idea about this setup?
I've found carbs from Kawasaki ZX-9R, 10 000km. Bike is destroyed.
Carbs are keihin G314 AKKL with 40mm inner diameter.
We've calculated that air flow on 900ccm engine on 14k rpm is same as 4a-ge small port on 6,6k rpm so it should be ideal in terms of sizing.
I might try this setup, but the bike-guy says i have to run them with airbox on. Since i would like to run them with trumpets/KN filters is there any problem with that, since these carbs need vacuum to work properly.
PLEASE SOME OPINIONS since it's kinda urgent.
I need to buy or return these babies.

build a box similar to the factory Solex set-up.
i know of these carbs being fitted to Datsun engines with awesome results.

40mm is quite a nice size if you ask some engine builders, for a 1.6. the FCR's which some japanese guys run are 41.5 from memory, and are said to be good to 170hp, which in reality is massive power for a 4ag.
ive spoken to a few bike wreckers/workshops, jets are definately available.
the hardest part is the ignition system. there is a company though that sells an ignition only computer, that will interface with the standard 4ag dizzy. cant remember the name right now though, they have a site, pm me and ill dig it up. theyre an aussie company, i think it was developed for LPG cars (which are basically carburetted) but ive spoken to one performance shop that has fitted them to alfa's ect. last time i check it was 330 for the kit.

Sure, they'll be fine, so long as you want carbs! Make sure you work out what it will cost for the carbs, manifolds, filters, etc. as well as ignition, tuning, etc., to see if it's not worth, in fact, just using EFI...
