Why buy all the parts when you aren't going to need most of them? I just rebuilt a set that pretty much only needed bowl gaskets, and even then, I wasn't sure they needed to be replaced. You can buy a lot of individual OEM parts like jets and gaskets at this place:
https://www.jetsrus.com/ and only get what you need. The guys in the know at the SOHC4 (old CBs) forum hate and advise against aftermarket jets, and while I haven't seen that same level of hate here, OEM doesn't cost that much more and you know they work. But, your jets are probably fine unless things are really corroded - get a gallon of Berrymans carb cleaner and soak off the crud. It's not as aggressive as the old stuff they sold once upon a time, but it still works well. I'd mostly be hoping the air cut and piston membranes are in good shape as opposed to the brass. They are far more delicate and expensive.
