yeah. that is kinda what i'm thinking too. you don't see them on very many 1/2 speed kits. pretty much vario only. even the dirtbikes i've never seen one that had aux ports without a power valve.

the other thing that adds to this line of thinking, is that the OEM's don't seem to be too concerned with minimizing the bridges between the main exhaust and aux ports. I would think if i was trying to loop scavenge into one large hole with two holes outbound, i'd want as narrow of a bridge as possible to minimize fluid shear going around and into those ports.

lots of cylinders with aux ports they just don't even give a shit, in some of the MHR cylinders they even have transfers right under them, further complicating the loop scavenge flow. Almost like they are there for a totally different exchange process... i.e. the blowdown, then recharge, and totally useless for loop exchange.
