Hey Terror I feel your pain, I'm pretty much in the same boat.
I have the same set-up with the Muzzy,AFE,Dynatek CDI,Dynatek hot coil(These help make a big difference),Dynajet kit.
Here's what I have going 195 main in front 190 rear,clip in the second position,and the springs from the kit,air screw out 3 turns with this set-up it did great till I hit the long straight away and thats were the problem started the vacuum on the carbs were not letting enough air in. I bought the hot coils from Alpine store(Dale) and then went to the Glamis it made a big difference from bottom to midrange nice improvement. I really could till if it made a big difference in the top end because I really never got it going in a long straight away.
Desert Dog has taking his Teryx to Alba and they say he's just a tad on the rich side but they said it's running strong and hard, they Dyno it and he said it dyno at 42 horsepower, I asked him to ask the tech at Alba to see what size jetts they put in. All he has is bolt-on no motor work.
