More on what I did to set them up and the cable adjustments:
So the first thing you'll want to do (as I quickly found out) is get the cables set up right with enough free play to get you started. I had to turn the angled pieces pretty much all the way into the tops of the carbs (make sure they still point forward) and then turn the cable adjusters themselves all the way in. Ideally, when you're done, you want like 1mm of free play in the cables just as they come out of the carbs, and a few mm of free play at the throttle. The slide should bottom out on the idle-adjuster screws and not bottom out with the cable holding them up (which would be zero free play).
So with enough free play in the cables, start it and set the idle-adjuster screws. I’m not sure if they all come set the same, but I had to turn both screws in a few turns to get it going. I then ran it on one cylinder at a time and got it to the same rpm on each side. Once you have it running on both cylinders again, you'll probably have to turn both idle-adjuster screws out an equal amount to get the rpm down where you want it.
Now turn the bike off and adjust the cable adjusters so the slides open at same time. Adjust only the one side that has more slack and make sure they just start to open at the exact same time (or like Pete mentioned, make sure they reach the top at the same time at WOT). Then check the free play of the cables at the carbs (gently pull the cable housing in and out of the adjuster, it should move just a little bit without lifting the slide). Both carburetors should not have an even amount of free play. If there is more than about 1mm of free play, turn out the cable adjusters on the tops of each carb and equal amount until your free play is where you want it.
Now start it up and check to make sure that when you give it a little gas, the slides don’t hang up at all and always come back down and bottom out.
Then put the filters on and either play with the air adjuster screws or if it seems to be running pretty well, go for a test ride. I set both my air screws to 1 turn out and it seemed good enough for a test run.
Well that’s pretty much what I did anyway!
