Kz750 Keihin tune

Hello everyone, I just bought a Kz 750 1980, I rebuilt the bike and the engine 0.5 oversize, mild porting and milling the head to have 10 10.5/1 compression.. I have pods filters and stock 4-1 exhaust
can you Guys tell me what size of jets you will use for this setup (Keihin 34mm diaphragm) 
thank you very much

This should get you in the ballpark.

If you are using cheap filters, then you may never get the carbs to work correctly. Some actually block the small air intake ports around the mouth of the carburetor. Name brands like APE, K&N and Uni will be fine.

I must admit that I do not understand why you would spend all that money and time getting the engine to intake better and then choke it down with the stock exhaust. 

Thank you, I want to order 4Pod Foam Uni filter, but Im waiting of the dimension.. I know they are 2” inlet(perfect for keihin) and 4”long.. but do you know if they will have enough place to be side by side?!!
Im planning to let the 4-1 exhaust, because the last guys has broken the muffler and is now Inside Wide open !! What will be the difference of order another 4-1 exhaust at 3-400$ ?again,  Thank you very much 

See attached link for recommended main jet increases on stock motors with air corrector jets fitted for pod use which is 150 across the 750 range.
For the comp increase you should jet a little higher and work down.
As TexasKZ previously mentioned retaining the stock exhaust won't help with getting the best out of your set up.
