Single Carb or Dual Quads which is better?

If you go with dual 4's, do yourself a favor and go with the Quick Fuel secondary metering plate. This way you can use standard jets to tune it with, instead of buying individual metering plates that jump 4 or 6 jet sizes if I remember right.

I have 2x4 600 with vacuum secondaries.
I find them little problem to set up and I haven't touch them since.

The factory linkage set up is very quick ratio and is tricky to throttle steer with. More like pressure on pressure off.

A single four gives you more pedal movement to throttle steer.

That being said I like the throttle response of the 2x4 very much.
