I had the stock 2x4 with 2-650 eddys and it was rich all the way around.... so I know 2-600's would feed it. And I agree jetting is a work of art and I tinkered a lot with my old setup. I have lots of metering rods, jets, and springs. Also the single plane does have a passage and that's nonsense you'll burn the front half up. You're getting idle circuit fuel which isn't much but it adds fuel.... I agree there will be distribution issues but hell the factory was so crappy the had to stagger jetting to help. I'm gonna run progressive and read the plugs.... thanks guys!
The factory inline intake was a dual plane, you're nuts if you think the Stage V is going to even remotely run right.
You have to run the Stage V intake 1:1. If you look closely you'll see it's actually 2 separate single plane plenums with a small crossover tube passage for balancing maybe ??? There is no way I would run it progressive ... but hey , it's your motor and your money ...
