When I had UNI, an A9 Cam, and an FMF exhaust, it took every bit of a 150 jet to get the correct AFR. Even right now, I would not be surprised if you needed a 140 with just the UNI. American Sportworks machines are unique in that they run very lean from the factory due to the machining process on their carbs. That is why you have to use what seems like such a large jet. In stock form, they like about a 130. I would actually start out with a 140 and see how it does with that.
