Welcome to the forum Billy, I always use the dynojet tuners kits myself, Harley sells them in the screamin begal catalog, I think the needles are more adjustable and like the lighter springs if it's a stock or moderate engine, I would not waste money on the thunder slide kits, but the tuners kit I have found to be a good investment. Also the 44mm CV carb performs well.
I'm sure other forum members will log in with some help also.
Here's a link to the catalog if your interested:

Billy, welcome to the HDTimeline forum and your first post. Chop has you covered...the HD (Kehin) CV carb is mighty fine, with plenty of years to refine and get it just right, only need to go to Self Help section for carb tuning info, with only couple #4 washers to raise needle a bit and use recommended jetting. Do not use drill and you should be good to go...

Yeah, the keihin CV is supposed to be one of the most versatile carbs Harley ever used. Should be ok with jets and or tuning as Chopper says unless you really go ape on the engine.
