Welcome aboard benster208 from north of Boston up in New Hampshire.
That is usually someone over tightening the emulsion tube that cracks that part if the body. There is carb numbers on the top of the carb bodies that you will need to get the correct series and which cylinder carb you'll need too(see pictures to verify your carb numbers, red arrow is pointing to #4)
There are a few members on here in Australia(I think there is an Australian section on here
)that will see your post, but put a ad in the wanted section with the carb series numbers and which cylinder it is, someone might have one available.
Did you put in rebuild kits in the carbs? It looks like someone put in aftermarket jets, those can be a problem with getting the bike to run properly. The aftermarket jets and float valves are not made to the same specs as the original brass parts made by Keihin. The original brass is cleanable if you have them??
