Ray-
I'm in the process of sciencing this installation out, so I don't have any pics. I looked at airflow requirements, and found that the Mikuni 38mm roundslide carbs should be adequate past 5000 rpm- the original B&B venturii dia is 34mm. I located a triple set from a snowmobile salvage yard for $120- need to go get them when the snow stops. Looks like the the best header setup for midrange up would be a tri-Y pairing cylinders 1,6; 2,5; and 3,4 into 1.
