If the tps mod doesn't eliminate it completely, try raising the clips one notch (closer to the flat end/away from the needle end). Worked wonders for my dyno-jet kitted used bike. How did the PO's ride 'em?

Ross,
Get your mixture screws to 2.25 turns out. 1.25 is too lean. Leave the rest of the jetting alone. There are no plugs on these carbs. The "D" shape is enough of a deterrant to most. Factory sends a tool with their kits. You might be able to make one out of small copper tubing if you're crafty.
The TPS will not cause surging. It is an input into the ECU and alters timing based on throttle position. You can slot those break-off screws with a dremel and turn them into flat heads, then just reuse 'em. That's what I did. Worked like a champ.
Lemme know if you have any more questions.

Oh well. Monday I guess. Thanks everyone for all the suggestions to get me up to speed!

Ah, forgot to mention that the TPS adjustment will change mileage slightly (better) and give better throttle response, much the same as adding an ignition advancer...which I also have, BTW.

So, I pulled the carbs for a second time today. Getting that down to a science... 
Cleaned the choke passages out well, and used the dremel to slot the screws on the TPS. Pulled them out and replaced them with some phillips I had...tried to adjust it but only got down to 654. So I pulled the two little steel collars out of the TPS and got that extra little bit of range I needed...508. Bingo! Turned out the mixture screws out another turn each, to 2.25 turns total. Put that all back together and moved on to the brakes. Cleaned out the master cylinder (it was FAR better off than the clutch master was) and bled everything out up front and in back. Brakes feel GREAT now. All I need is some tires and then the chain and sprocket. I still haven't gotten around to checking my gearing yet... But until I get some miles on it, I won't know what I think of the current gearing anyway. I generally want lots of grunt out of this thing, and think that short gearing will be my interest, but don't want to throw the speedo off too bad either. Suppose I could buy a speedo-healer somewhere down the line if it matters to me. Assuming there isn't one already on the bike. Haven't looked though. There is a shift light on it, but with the tires the way they are, I haven't yet had a chance to see it light up yet (it spun the tire repeatedly the other night, its so old, hard and bald.) Hopefully monday I'll see the tires; Its killing me having sunny weather and not being able to take this thing out!

Oh, if only that were true. The Bandit has been in a stage of partial disassembly for quite some time, as I slowly do things on it. Its at my buddies shop right now, and the cylinders are being sent out to be bored for the 1216cc low comp JE's that I have for it. Then have to get the Megasquirt sorted out. Gonna be running a set of throttle bodies from a 2001(?) R1. My first turbo setup on it was a Mr. Turbo kit. It was fine. Produced pretty kick butt power, but the delivery left a little something to be desired IMHO. Great for drag racing, but not really accessible on the street without blatantly breaking lots of speed laws. This setup, will be blow through, as opposed to the draw through setup I had before, and ought to have great manners, along with more power everywhere. In the meantime, the SH ought to keep me entertained on my commute, and should be good for scratching around the bends. The bandit handles pretty well the way I have it setup now, but the SH should be much better! The Ninja...well its getting a few things finished up on it, and is gonna find a new home.
