Ryan, please be assured that I'm not trying to be snide with the advice I'm about to give you. Be aware that once the intake and exhaust systems have been altered, any set of jetting specs that even the best tuner comes up with at a distance will be an approximation, and fine tuning will be up to you; plug and play is only going to happen if you get very, very lucky. Having a shop jet your carburetors will usually result in frustration and waste of money unless, again, you're very, very lucky. At the bottom line, the only folks who end up with good results from old motorcycles are those who turn their own wrenches, and that's especially true when it comes to old motorcycles that have been modified. Carb tuning isn't that difficult if you start with a good baseline, make small changes one at a time, and listen to what your motor is trying to tell you.
I seldom have a difference of opinion with WR or Skull, and this one is offered with sincere respect: IMO age has made the OE vacuum carburetors touchy for a novice to work on, and I wouldn't recommend them to you. Throttle shaft seals almost always require replacement, and I'm seeing more of these carbs with wear on the throttle shaft seats, so that air leaks occur even after fresh seals are installed. Mine is just one opinion, and like another item, we all have 'em.
That having been said, Oldskool Carbs comes highly recommended.
