Also, on the idle mixture adjustment, what do you mean "
Turn each adjustment screw to get the highest RPMs"? Should I get the bike warm, and literally turn the screws until the RPMs raise, and find the highest point and leave it there? It's certainly different than my method.
Thanks!

If you have 108s, I would try them. In stock form, they are too rich - so it may be close. We ran them with pods and a leaky exhaust - and it ran strong on top.
For the idle mixture - yes - you are trying to find the highest RPM setting you can get by adjusting the idle mixture screws. I like to make it about 1/8-turn richer (out) from there. It will most likely be higher than it is now, so you just turn the idle speed screw to get it back to 1300 or so.
This diagram shows the different fuel circuits -

Did the kit have different carb needles?
