OK, I bought the Victory book. The chart says the jet just pulls out, yeah, right.
So, how does one remove the needle jet without messing it up with pliers?
Maybe strip everything from the carb and put the body in the oven?

pull the bowl, and remove the slide. turn it upside down, remove the main jet and ring. then use a soft drift to push the needle jet up through the upper part of the body.

Yeah,
DON'T use pliers, or anything hard! ..... MAYBE tweezers to re-insert the needle jet, upon reassembly...

There is a machined step in the carb body, the needle jet cannot be pushed 'down'. It must be pushed up through the [round] slide area.
There is also a locating pin... It orientates the needle jet...

You can also, on most Mikuni's I've seen, put the main jet back on the needle jet, after removing the 'ring', or washer as I call it, and use the flat face of the main jet as a pushing surface. JUST snug the jet...

Anything else?

when all that fails, torch the carb body until it's just too hot to hold, then push the jet out. (wear gloves)

Thank you gentlemen.
That was easy enough with a wee bit of heat. I'm always leery of taking even a small hammer to anything without advice.
Now, at least I know they both have p-4 needle jets.
