The big carby always brigade misses the simple point that a smaller carb can change numerous things such as distribution [ A/F ratio for each cyl ], droplet size etc such that the smaller carb could make more power. Bigger carb is not absolute on every engine. Look at the old MP mods to intake manifolds with popsicle sticks to try & fix uneven A/F ratios in the runners. Try a different carb, these mods might not work.

I agree given some circumstances the smaller carb “could” make more power. But in the motortrend article posted, there is proof that the bigger carbs DID make more power. The poor running was a result of poor tuning. 14 wheel hp is a fairly significant gain at ~400whp, I don’t know a lot of guys willing to give that up, if they’re serious. Now the same would be true if a guy had an 850 and a 650 picked up 14whp.
