1980 KZ750 Pilot Air Fuel screw size

I have a 1980 KZ750 LTD U.S. model. I need to know what the thread size is on the air fuel screws. Number 2 carb was really damaged when I bought the bike. I bought a nice used one and rebuilt all the carbs. I just ordered new pilot air fuel mixture screws. I want to clean the threads before I install the new screws. any help is greatly welcomed.

6mm x .75

Thank you. so much some one told me it was 6 X .50. I know how to rebuild carbs. I just don't know the sizes of certain things once I learn the size I write it down .

Your restoration on your bike is amazing. I love all the photos you have of it.

Mikuni pilot screws for their BS CV carbs use that size thread.

Thanks for the kind comments about my build thread.:blush:

My carbs are KEIHIN. Thank you so much for your help

Here are the O-ring sizes for your carbs. The interconnect tubes and main feed Tee O-rings get hard and brittle and the only way to change them is to ungang the carbs.

Pilot Screw: 1.2 x 2.6
Pilot Plug: 1.5 x 2.8
Fuel Transfer Tubes: 2.0 x 5.5
Drain Screws: 1.4 x 4.0
Float Bowl: 2.0 x 67

thank you greatly for your help.
