Help me settle an argument

Mmmmm, interesting.

I'm usually not one to just throw money at a problem hoping it'll get fixed, so that's why I stood strong with my decision to keep the 650 dp. I remember reading an article somewhere talking about carb sizing and one of the things they did was talk about vacuum at WOT. So, when I hooked up a gauge to my junk and saw 1" vacuum I thought I was good.
