PSI manifolds
I just sold Bruce 24 Big Air carbs, 46, 48, 50 & 42' & 52's and 3 sets of T-cat triple, 3 sets of 900's, and a ton of other parts so give him a call, I was a big fan of Big Airs but soon found out they pop off 3/4 of the way up a steep pull, not good, also found the lectrons to vaper and pull harder, 44's or 48's on a Triple will suprise you, I run a Pro Stoick 1000 for, the steep stuff, Lectrons will not pop off and run stronger with no flat spots, that is why I sold everythging, I now run lectrons on my 4 big triples. Good Luck. Jim in Quincy CA
