For those of you that don't know already, this was posted on the http://www.sigma-galant.com/ forums by user Superscan811. Here is a quick guide he posted about how to perform this operation:
"Basic CV carb setup:
You will need a fuel pressure regulator that can regulate down to 0.5psi. These carbs are gravity fed on the motorbike so pushing anything more tha 1.5psi isn't a good thing. I modified a standard holley carb fuel pressure regulator by compressing the internal spring a bit. This allowed me to be able to regulate the fuel pressure down to 0.25psi.
Based on my current setup of the quad 38mm Mikuni's off a 1995 Suzuki GSX-R750:
1. You shouldn't need to change either of the Idle jets (fuel and air blead). The idle AFR I'm currently running is around 17:1, without any issues.
2. Standard float height.
3. Main Fuel jet size 1.55mm.
4. Needle position will be determined by the wear on the "needle Jet", try the middle position first.
The only other thing to I'd recommend is to attach a cable for the choke. I only use it to start the engine on a cold morning. For the rest of the day, it isn't needed. Because CV carbs don't have an acceleration fuel pump, pumping the accelerator when trying to start the car does nothing."
