I got the replacement used Mikuni today, and got it installed. However, now it has a high idle (2000 rpms), and I have to try and figure out what's wrong. I'm pretty sure I have all the rubber lines and caps in the right place (the fuel lines and water line are obvious). I'm hoping it's something simple as having some lines crossed, as opposed to the replacement carb malfunctioning. It has a 30-day warranty, so I need to figure it out in the next couple of weeks. But when it finally started (carb was dry), it seemed to run better than before, so I'm anxious to see what it drives like with working secondaries!

Item of note. On the stock carb, on the side that faces the valve cover, there's a small fitting at the base of the carb that angles up at 90-degrees, and has a rubber cap. There's another fitting next to it, that's angled slightly upwards, that was uncapped. When I installed the replacement carb, I capped this second fitting, that was the only difference I remember doing between the stock carb and replacement carb. In an attempt to get the idle down, I removed this rubber cap, and the rpms shot up to almost 3000 rpms, and wouldn't go back down. So tomorrow I'm going to put the cap back on, cross my fingers, and hope for the best...
