Old thread bumping...
I used 1980's-90's Suzuki GS1100/GSX1100 4 carb rack and jet it to your 4 banger as they only cost $100 for the setup and they have Stage 1-3 kits for these too.
Tuning depends on if you plan to run 1 carb per cyl or the 4 carbs feed a common plenum.
1per cyl requires carb syncing but you can tune individually per cyl and make more power and throttle response is higher.
4common fed acts as a large carb feeding a big area where they all draw from, no tuning needed and prob get a some lag but wont be as sensitive.
