My 100-6 has a MKI engine .060 over, Issky perfomance cam and it has a
balanced engine. I bought a tri carb setup, traded it for a pair of HD8s
and built a cable throttle system. Im very happy with it, other than hot
idle issues.  I get around 23 mpg on the road and its more responsive. But
I hsve to say three carbs look great under the bonnet. As others have ssid,
without hotting up the engine, no need to go bigger cfm.
