Have an 81 KZ440 LTD, bought it with pods and free flowing exhaust. It's running very lean and I can't go full throttle without major lag and then starts overheating. What size jets do I need in the carbs to eliminate this problem? 70 main and 90 secondary is what it has now

You will need more than just jets.
Get the DynoJet jet kit for the KZ750H which is a 4 cylinder.
The carbs are almost identical to each other between the two bikes
That is the best anyone can do short of having access to the Sudco warehouse.
As for the use of slide carbs anything larger than a 28mm is overkill.
